School Transit-Oriented Development

Transit-oriented development, or TOD, means building more stuff in places with good access to public transportation, typically the immediate vicinity of a train station. This way people have more convenient access to transit and are encouraged to take it because they live or work near the train, or ideally both. In practice, American implementations heavily focus on residential TOD, and secondarily on commercial TOD, the latter focusing more on office than retail. I covered some retail issues here; in this post, I’m going to look at a completely different form of TOD, namely public-sector institutions that government at various levels can choose the location of by fiat. These includes schools, government offices, and cultural institutions like museums. Of these, the most important are schools, since a huge share of the population consists of schoolchildren, who need convenient transportation to class.

This principle here is that the state or the city can site public schools where it wants, whether it’s by diktat or by inducements through funding for school construction. This occurs even in situations with a great deal of autonomy: American suburban schools are autocephalous, but still receive state funding for school construction, and if anything that incentivizes moving to new suburban campuses inaccessible by public transit. Other cultural institutes are usually less autonomous and more strapped for cash, and getting them to move to where it’s easier for people to access them without a car should be easier.

School siting: central cities

Urban schools tend to spread all over the city. There are more schools in denser and younger neighborhoods; there also are more high-end schools (Gymnasiums, etc.) in richer neighborhoods. But overall, there isn’t much clustering. For example, here is what I get when Googling both Gymnasiums in Berlin:

There are many Gymnasiums in rich areas like Wilmersdorf and few in poor areas (the map shows one in Neukölln and none in Gesundbrunnen and Wedding, although a few that aren’t shown at this zoom level do exist). But overall, the school locations are not especially rail-oriented. They’re strewn all over the middle-class parts of the city, even though most students do not live close enough to walk. Only the most specialized of the elite schools is in city center, the French school.

The situation in New York is similar to that of Berlin – the schools in the city are all over. This is despite the fact that there’s extensive school choice at the high school level, so that students typically take the subway and bus network over long distances. New York’s school stratification is not the same as Berlin’s – its Specialized High Schools serve the top 3% of city population, Germany’s Gymnasiums serve maybe 30% – but there, too, schools that explicitly aim to draw from all over the city are located all over the city. Only the most elite of New York’s schools, Stuyvesant, is in the central business district, namely in Lower Manhattan; the second and third most elite, Bronx Science and Brooklyn Tech, are just outside Downtown Brooklyn and in the North Bronx, respectively. A huge fraction of Bronx Science’s student population commutes from feeder neighborhoods like Flushing, Sunset Park, Chinatown, Jackson Heights, and the Upper West Side, and has to wake up early in the morning for an hour-long commute.

If schools are not just for very local neighborhood children, then they should not be isotropic, or even middle-class-isotropic as in Berlin. They should be in areas that are easily accessible by the city’s rapid transit network, on the theory that the time of children, too, is valuable, and replacing an hour-long commute with a half-hour one has noticeable benefits to child welfare and educational outcomes.

Urban school nodes

So to improve transit access to school in transit cities, it’s useful to get schools to move to be closer to key nodes on the rail network. City center may be too expensive – the highest and best use of land around Times Square or Pariser Platz is not a school. But there are other useful nodes.

The first class of good locations is central and near-center areas that don’t have huge business demand. In New York, Lower Manhattan and Downtown Brooklyn both qualify – business prefers Midtown. In Berlin, there are a lot of areas in Mitte that don’t have the development intensity of Potsdamer Platz, and to some extent the French school picked such an area, on the margin of Mitte.

The second is key connection points on the rail network that are not in the center. Berlin is rich in such connections thanks to the Ring. To some extent there are a bunch of schools close to Ringbahn stations, but this isn’t perfect, and for example the Europasportspark shown on the map is between two Ringbahn stations, at one of the few arterial roads through the Ring that doesn’t have an S-Bahn station. In New York, there is no ring, so connections are more sporadic; desirable nodes may include Queensborough Plaza, Metropolitan/Lorimer in Williamsburg, and East New York.

East New York supplies an example of the third class: an area that is rich in transit connections but is commercially undesirable because the population is poor. (The Berlin equivalent is Gesundbrunnen – non-German readers would be astounded by the bile Germans I know, even leftists who vote for anti-racist politicians, heap on U8 and on Gesundbrunnen and Neukölln.) Since everyone goes to school, even working-class children, it is valuable to site schools and other cultural amenities in such areas for easy accessibility.

One important caveat is that freeways, which make office and retail more attractive, have the opposite effect on schools. Air pollution makes learning more difficult, and children do not own cars and thus do not benefit from the convenience offered by the car. If rail lines are near freeways, then schools should be set somewhat away, on the principle that the extra 5-minute walk is worth the gain in health from not sitting hours in a polluted environment.

The suburbs

Outside the cities, the place for schools is the same as that for local retail and offices: the town center, with a regional rail station offering frequent access by train and timed connections by bus. Even when the student population is local, as it is in American suburbs, the density is too low for people to walk, forcing some kind of mechanized transportation. For this, the school bus is a poor option – it is capital-intensive, requiring what is in effect a second bus system, one that is as useless for non-students as the regular buses are for students if the school is far away from the local transit network.

Instead, a central school location means that the suburban bus network, oriented around city center, is useful for students. It increases transportation efficiency rather than decreasing it – there is no duplication of service, and the school peaks don’t usually coincide with other travel peaks, like the office worker peak and the retail worker peak. The bus network, designed around a 15- or 30-minute clockface schedule, also means that students can stay in longer, if they have on-campus club activity or if they have things to do in the town center, such as going shopping.

In some distant suburbs the school peak, arriving around 8 in the morning, may be the same as the peak for office workers who take the bus to the train to go to the central city. This isn’t necessarily a bad thing – for parents who insist on driving, this makes it easier to drop off children on the way to work. If this turns out to create real congestion on the bus, then the solution is to move school start time later, to 9 or so.

It’s crucial to use state power to effect this change when possible. For example, Massachusetts funds school construction through state funds but not renovation, which has encouraged schools to move to new campuses, generally in harder-to-reach areas. Fitchburg’s high school used to be in city center but recently moved to a suburban location close to nothing. Even in environments with a lot of local autonomy, the state should fund school construction in more central areas.

YIMBY and Production Theory

Two years ago, at a Breakthrough Institute conference, I met Tory Gattis in real life for the first time, having known him on the Internet for maybe ten years. He was doing a debate with Kim-Mai Cutler, except they mostly agreed, and I think the reason for the agreement is their conception of production theory.

Tory’s opening was the most illuminating part, and only then, in 2018, did I understand why in 2008-9 I was so interested in reading him even though he was always pro-car, an unabashed Houston booster, and a fan of Joel Kotkin. He opened by defining himself in opposition to three ideas from the 2000s: smart growth, New Urbanism, and Richard Florida’s conception of the creative class. And there is clicked: these three ideas are all about cities as loci of consumption. Before YIMBYism, when Market Urbanism was an obscure libertarian blog, there wasn’t a lot in there for people who think in terms of urban job and residential growth, who think that consumption follows production and not the reverse.

New Urbanism and Richard Florida’s theory both hold, in different ways, that if cities make themselves nice to specific (different) classes of people, they will attract people who are morally and economically better to have as residents, stimulating further growth. In New Urbanism, this is about designing cities based on principles that are held to be objectively nicer for residents; this quickly boils down to the “when we’re expensive this proves we’re desirable, when you’re expensive this proves you’re unaffordable” principle. Ironically, the blog Old Urbanist holds something similar, it just posits a different (generally better) set of design principles. Richard Florida is less about physical design and more about community amenities for groups that in the 2000s he held were more creative, like gay people, for whom he prescribed more gay bars.

The irony is that even as he has increasingly repudiated the creative class theory, Florida maintains his attachment to consumption theory of cities. The difference is that 18 years ago he thought that building New Left-coded amenities like bike lanes and gay bars would attract creatives and increase social and economic outcomes and now he believes the same except that the final outcome is to raise rents. Tory was critiquing the idea already in the late 2000s, pointing out the anemic outcomes of cities whose development policy was consumption-based – it’s not that they were creating jobs but their rents was rising, but rather that they kept having low job growth and net emigration.

Smart growth is somewhat different, in that it is not explicitly an endorsement of consumption theory. However, in practice its effect is always to make development harder, not easier. The contrast is with transit-oriented development, which in theory means the same thing but in practice counts dwellings build near train stations and not dwellings prevented from being built far from train stations. California celebrates smart growth and smart growth celebrates California, and in practice the effect of California’s housing policy for the last 50 or so years has been to make all housing hard to build, creating a supply shortage.

In comes YIMBY. The central policy proposal of YIMBYism is to build more housing in rich, expensive cities. But the central tenet of YIMBYism is that people’s decisions about where to move to are driven by production rather than by consumption – that is, that people move for work rather than for the sort of consumption amenities that urban policymakers focus on.

This does not mean consumption amenities do not exist. They clearly do, but they operate at different levels from that of neighborhood activism. Albouy-Ehrlich-Liu find extensive consumption effects on urban desirability, but these are almost all geographic, like mild weather and proximity to the coast; only one is affected by policy, air quality, and that is a regional rather than local variable. Other policy-relevant consumption variables may be crime and education, neither of which is that responsive to local-level policy, especially when it pertains to development. People like New York and London and Paris, and maybe they’ll like them more if they provide public services like clean air better, but they’ll certainly not like them less if they replace 150-year-old 4-story buildings with 50-story ones. What people like about New York and London and Paris is not the architecture or the size of the buildings, but the dense job networks.

A Bigger City is a Better City

There’s a tendency among a number of important American YIMBYs that bothers me – they speak of development as a bad thing, a great burden that must be shared equally across neighborhoods. I’ve even seen this take regarding immigration, portraying it as such a terrible burden that Germany must undertake to redeem itself after the Holocaust. The underlying assumption is that growth is bad, and the ideal world is static and has people living in small communities.

But what if growth is good? What if more urban development is good? What if immigration is good, and immigrants are good people individually and collectively?

Growth is good

There’s a “growth for its own sake is the ideology of the cancer cell” meme out there. Well, no. Growth is not for its own sake. It’s for the sake of the things you can do in a society that produces more stuff: live longer, own refrigerators and other appliances, travel beyond walking range, communicate with people beyond travel range, get your own room, eat more interesting food than whatever scraps concentration camp prisoners fight over, wear more interesting clothes than concentration camp prisoner uniform, play interesting games, etc.

What is true is that no single element of these is in perfect correlation with wealth. You can even devise a large subset of these that aren’t, and focus on places that are exceptional relative to their income levels; Kerala is popular for its high literacy and life expectancy relative to its wealth. But usually these early investments then pay off in growth – this was the case in 1960s and 70s’ Korea, which was approaching universal literacy at the start of this period with astonishingly low incomes, and then used its advantage in relatively skilled, low-wage work to industrialize.

Urban development is good

The ability to access more stuff easily is a good thing and there’s a reason both employers and residents pay extra to have it. More and bigger buildings stimulate this kind of access. On the production side, this means thicker social networks for people who work in related industries and can come up with new innovations – this is why the tech industry sticks in San Francisco and environs, and not the bay view or the state of California’s public services. This, in turn, raises wages. On the consumption side, this means more variety in what to buy.

Moreover, this is true down to the neighborhood level. A denser neighborhood has more amenities, because more people is a good thing, because new people stimulate new social events, new consumption, and new opportunities for job access. If more people move to your neighborhood, that means first of all that employers are more likely to site jobs where convenient for you, and second of all that the city is likelier to want to build more subway lines in your direction.

A corollary of this is that private developers, as a class, are good, because they convert factors of production like labor and capital into finished, habitable apartments and offices. Yes, they can individually be terrible people. But collectively as a class their effect is good and the state needs to stop treating them as a source of loot to be doled to sympathetic neighborhood groups.

The most frustrating thing about it is that New York specifically likes to extol its own size as a reason for its supposed greatness. But then the idea that an even bigger city is a better city makes the political system there wince, and therefore the city permitted not many more than 20,000 housing units per year at the peak of the pre-virus economy, about one quarter the per capita rate of the Seoul metropolitan region or Tokyo (the city proper, but I think the suburbs have similar housing growth), and one third that of Ile-de-France.

Immigrants are good

Vancouver is a racist city, and I say this having lived in Israel. I somehow found myself in a room at a meetup where an all-white group of people were talking about black men’s penis size. Anti-Semitism, anti-black racism, Sinophobia, hate for indigenous people: you name it, I saw it there, used casually, by people who didn’t even think they were saying something controversial. The representatives of the people of that city have come across the realization that there is extensive immigration to their city and therefore it may be prudent to choke housing development because it’s all for immigrants anyway.

There’s a weird kind of defensiveness about immigration, even in societies where it’s fairly popular. Germany and Sweden both think they’re shouldering a great burden by taking in refugees, and even Germans who identify as left-wing and antiracist seem scared of diverse neighborhoods that immigrants of all social classes don’t find anything wrong with. But Germans at least have the excuse of not being used to diversity, and I think they’re slowly learning to be more tolerant. Vancouverites are used to diversity and decided they prefer racial purity to growth. Housing growth in Vancouver was healthy before the crisis but a lot of political forces in the city seem intent on making sure this doesn’t happen again, and with the transit-oriented development sites filling fast, the region will soon have to make tough decisions on upzoning single-family neighborhoods 600 meters from the train rather than 100 meters.

For the same reason a bigger city is a better city, the movement of immigrants into a country is an unalloyed good for the recipient country, unless perhaps that country is extremely dependent on primary resources, which Germany isn’t and even British Columbia isn’t.

Developers may be individually bad people but collectively good as a class; with immigrants, the good is both individual and collective. Immigrants as individuals are good, and it’s better for a country to have more of them (us, really): if anyone wants me to babble about all the statistics about employment (even for refugees in Germany), lower crime rates, cultural emphasis on skills and education, etc., I’ll be happy to do so in comments. Immigrants as a collective are likewise good, through introducing more cultural variety to a place and promoting cultural and social ties to parts of the world this place may not have thought to learn much from.

New York is Shrinking

The US Census Bureau has just released 2019 population estimates by county. Metro New York, after slowly rising for decades more than making up the 1970s losses, went down by 60,000 people, or 0.3% of the population. The city is down 53,000 people.

Why?

The city chooses stagnation and ignorance. In the 1970s, the city was losing an average of 80,000 people per year, but the situation now is profoundly different. Incomes are up: the metro area’s per capita income as a proportion of the US average went from 126% in 1970 to 118% in 1980; but more recently it went from 135% in 2010-5 to 141% in 2018, the last year for which the BEA has data. Crime is down, the murder rate falling below the national average starting in 2013. Rent is up, sending a strong signal: more people want to live here.

But the entire political constellation of the city chooses not to grow. Housing growth is anemic, permits averaging around 21,000 per year in 2010-9, maybe 2.6 per 1,000 New York residents. It accelerated over the decade but not by much, reaching 26,500 in 2019, or 3.2/1,000. In the in-state suburbs, growth is even lower, less than 1 unit per 1,000 in each of Nassau, Suffolk, and Westchester Counties. New Jersey has somewhat higher growth rate, around 4/1,000, thanks to the Mount Laurel doctrine requiring high-cost municipalities to approve some affordable housing, which they typically do in the most out-of-the-way place they can find. The metro area overall approves about the same amount of housing as the city proper, around 2.5/1,000.

The most recent data I have for Korea is from the first half of 2019. In six months, Seoul, a shrinking city of 9.5 million, approved 38,000 dwellings, and the metro area writ large approved 129,000 on a population of about 26 million, an annualized rate of 10/1,000 (less in the city, more in the suburbs). This is a suburbanizing region, but suburbanization often means moving to a planned new town built on top of a subway or commuter rail line, like Ilsan, Bundang, and Anyang.

It’s not Tokyo that has high housing growth. It’s Tokyo, and Seoul, and to a lesser extent the metro area of Taipei (more suburbs than city proper), and Paris. In the presence of a strong economy and a state that doesn’t choose stagnation the way rich American regions choose with local empowerment, housing growth in a large city should be high, as more people want to move there to take advantage of its higher incomes and opportunities.

But New York chose differently. It chose stagnation and eventually decline. It chose to be expensive.

Why are they like this?

The US has an unusual system of governance, in which not only is there a separation of federal and state governments, as in Germany or Canada or Australia or Switzerland, but also the states delegate unusual powers to local governments. Education, policing, and housing are largely local responsibilities. Even when states do get involved, there is usually no partisan competition (most states are safe), leading to empowerment of local representatives on what are considered local issues, and even when there is people vote based on national issues.

But even that raises questions. For example, why do locals consider new development bad? Even YIMBY activists let NIMBYs whip them into thinking this way – they talk about sharing the burden, as if new buildings and new people are a burden that everyone must endure for some grand moral reason.

What if the reason people take it for granted that growth is bad is that the people who are most locally empowered are a specific anti-growth lobby? People who work for a living don’t have time to go to a citizen engagement meeting at 3 in the afternoon. They work and socialize with people from other neighborhoods, so they have little interest in neighborhood rags that report individual counts of parking spaces lost to a bus lane. They are far more interested in job growth than in hobby community gardens. A political system that requires very high levels of local social capital for one’s opinions to count will naturally undervalue their opinions and overvalue those of idle people and professional intermediaries.

The high levels of Covid-19 infection in New York are part of this system. The specific cause is not hyperlocalism, but rather the murky authority of the state. The city is plagued by the feud between Mayor de Blasio and Governor Cuomo. Both enjoy unlimited executive power, I think Cuomo more so than de Blasio. Both need it for their higher political aspirations. But neither can have it while the other exists as an independent political entity, nor is there a clear delineation of state and local authority. Thus, they are obligated to sabotage each other’s ideas, to the detriment of the city that has the misfortune to be governed by them. The entire West delayed its reaction to the virus, but New York especially so, as Cuomo and de Blasio tried denying each other credit.

Professional ignorance

I’ve been writing a lot about the role of incuriosity in high construction costs in the English-speaking world in general, and New York in particular – see for example this recent coronavirus-tainted piece, or this more random piece about Metro-North’s executives’ ignorance.

But this can apply more generally, as it did to the virus. Americans are quite provincial when it comes to the rest of the world, and New Yorkers especially so – go ahead, try telling a New Yorker that some other city does something better than New York. The out-of-town comparison, a powerful tool that places that view themselves as more peripheral (like Israel) use to correct errors, dos not work in a place like New York. New York literally made the collective decision to die and not to learn from the rest of the world. Mass death is not making New Yorkers demand the immediate removal of their mass manslaughterers who are their governor and mayor; why would a dip in population?

Part of it is related to local empowerment. Acquiring local social capital comes at the expense of worldliness; those years one spends learning foreign languages, living abroad, and socializing with foreigners are dead years for most political ambitions, including all ambitions that start locally.

But an even greater part of it is that New York self-perceives as the center of the world, which is not true elsewhere. Korea self-flagellates all the time: about its legal system (it adopted a limited jury system in 2009), about its engineering (see e.g. here), about its elevated air pollution levels (it’s adopting EU standards). The United States instead views all variations with the rest of the world as evidence of America’s unique greatness, and New York does the same both internationally and domestically. The city brims with immigrants, and yet it tells them, your home country is deficient and you must become a real New Yorker, that is someone whose world does not extend past city limits, to be a whole person. Until that changes, the government of New York will remain managed by dregs and incompetents and housing, transportation, and as we see health care will earn the mockery of other big first-world cities.

On Envying Canada

In England and Wales, 15.9% of workers get to work on public transport, and in France, 14.9% do. In Canada, the figure is close: 12.4%, and this is without a London or Paris to run up the score in. Vancouver is a metro region of 2.5 million people and 1.2 million workers, comparable in size to the metropolitan counties in England and to the metro area of Lyon; at 20.4%, it has a higher public transport modal share than all of them, though it is barely higher than Lyon with its 19.9% share. Calgary, Ottawa, Edmonton, and Winnipeg are likewise collectively respectable by the standards of similar-size French regions, such as the departments of Bouches-du-Rhône (Marseille), Alpes-Maritimes (Nice), Gironde (Bordeaux), Haute-Garonne (Toulouse), and Bas-Rhin (Strasbourg).

As a result, Jarrett Walker likes telling American cities and transit agencies to stop envying Europe and start envying Canada instead. Canada is nearby, speaks the same language, and has similar street layout, all of which contribute to its familiarity to Americans. If Europe has the exotic mystique of the foreign, let alone East Asia, Canada is familiar enough to Americans that the noticeable differences are a cultural uncanny valley.

And yet, I am of two minds on this. The most consistent transit revival in Canada has been in Vancouver, whose modal share went from 14.3% in 1996 to 20.4% in 2016 – and the 2016 census was taken before the Evergreen extension of the Millennium Line opened. TransLink has certainly been doing a lot of good things to get to this point. And yet, there’s a serious risk to Canadian public transport in the future: construction costs have exploded, going from Continental European 15 years ago to American today.

The five legs of good transit

I was asked earlier today what a good political agenda for public transportation would be. I gave four answers, like the four legs of a chair, and later realized that I missed a fifth point.

  1. Fuel taxes and other traffic suppression measures (such as Singapore and Israel’s car taxes). Petrol costs about €1.40/liter in Germany and France; diesel is cheaper but being phased out because of its outsize impact on pollution.
  2. Investment in new urban and intercity lines, such as the Madrid Metro expansion program since the 1990s or Grand Paris Express. This is measured in kilometers and not euros, so lower construction costs generally translate to more investment, hence Madrid’s huge metro network.
  3. Interagency cooperation within metropolitan regions and on intercity rail lines where appropriate. This includes fare integration, schedule integration, and timetable-infrastructure integration.
  4. Urban upzoning, including both residential densification in urban neighborhoods and commercialization in and around city center.
  5. Street space reallocation from cars toward pedestrians, bikes, and buses.

We can rate how Canada (by which I really mean Vancouver) does on this rubric:

  1. The fuel tax in Canada is much lower than in Europe, contributing to high driving rates. In Toronto, gasoline currently costs $1.19/liter, which is about €0.85/l. But Vancouver fuel taxes are higher, raising the price to about $1.53/l, around €1.06/l.
  2. Canadian construction costs are so high that investment in new lines is limited. Vancouver has been procrastinating building the Broadway subway to UBC until costs rose to the point that the budget is only enough to build the line halfway there.
  3. Vancouver and Toronto both have good bus-rapid transit integration, but there is no integration with commuter rail; Montreal even severed a key commuter line to build a private driverless rapid transit line. In Vancouver, bus and SkyTrain fares have decoupled due to political fallout from the botched smartcard implementation.
  4. Vancouver is arguably the YIMBYest Western city, building around 10 housing units per 1,000 people every year in the last few years. Toronto’s housing construction rate is lower but still respectable by European standards, let alone American ones.
  5. There are bike lanes but not on the major streets. If there are bus lanes, I didn’t see any of them when I lived in Vancouver, and I traveled a lot in the city as well as the suburbs.

Vancouver’s transit past and future

Looking at the above legs of what makes for good public transport, there is only one thing about Canada that truly shines: urban redevelopment. Toronto, a metro area of 6 million people, has two subway mainlines, and Montreal, with 4 million people, has 2.5. Vancouver has 1.5 lines – its three SkyTrain mainlines are one-tailed. By the same calculation, Berlin has 6.5 U- and 3 S-Bahn mainlines, and Madrid has 2 Cercanías lines and 7 metro lines. Moreover, high construction costs and political resistance from various GO Transit interests make it difficult for Canadian cities to add more rapid transit.

To the extent Vancouver has a sizable SkyTrain network, it’s that it was able to build elevated and cut-and-cover lines in the past. This is no longer possible for future expansion, except possibly toward Langley. The merchant lawsuits over the Canada Line’s construction impacts have ensured that the Broadway subway will be bored. Furthermore, the region’s politics make it impossible to just build Broadway all the way to the end: Surrey has insisted on some construction within its municipal area, so the region has had to pair half the Broadway subway with a SkyTrain extension to the Langley sprawl.

Put in other words, the growth in Vancouver transit ridership is not so much about building more of a network, but about adding housing and jobs around the network that has been around since the 1980s. The ridership on the Millennium and Canada Lines is growing but remains far below that on the Expo Line. There is potential for further increase in ridership as the neighborhoods along the Canada Line have finally been rezoned, but even that will hit a limit pretty quickly – the Canada Line was built with low capacity, and the Millennium Line doesn’t enter Downtown and will only serve near-Downtown job centers.

Potemkin bus networks

When Jarrett tells American cities to envy Canada, he generally talks about the urban bus networks. Toronto and Vancouver have strong bus grids, with buses coming at worst every 8 minutes during the daytime off-peak. Both cities have grids of major streets, as is normal for so many North American cities, and copying the apparent features of these grids is attractive to American transit managers.

And yet, trying to just set up a bus grid in your average American city yields Potemkin buses. Vancouver and Toronto have bus grids that rely on connections to rapid transit lines. In both cities, transit usage is disproportionately about commutes either to or from a city core defined by a 5 kilometer radius from city hall. Moreover, the growth in public transport commuting in both cities since 1996 has been almost exclusively about such commutes, and not about everywhere-to-everywhere commutes from outside this radius. Within this radius, public transportation is dominated by rail, not buses.

The buses in Toronto and Vancouver have several key roles to play. First, as noted above, they connect to rapid transit nodes or to SeaBus in North Vancouver. Second, they connect to job centers that exist because of rapid transit, for example Metrotown at the eastern end of Vancouver’s 49. And third, there is the sui generis case of UBC. All of these roles create strong ridership, supporting high enough frequency that people make untimed transfers.

But even then, there are problems common to all North American buses. The stop spacing is too tight – 200 meters rather than 400-500, with frequency-splitting rapid buses on a handful of very strong routes like 4th Avenue and Broadway. There is no all-door boarding except on a handful of specially-branded B-line buses. There are no bus lanes.

One American city has similar characteristics to Toronto and Vancouver when it comes to buses: Chicago. Elsewhere, just copying the bus grid of Vancouver will yield nothing, because ultimately nobody is going to connect between two mixed-traffic buses that run every 15 minutes, untimed, if they can afford any better. In Chicago, the situation is different, but what the city most needs is integration between Metra and CTA services, which requires looking at European rather than Canadian models.

Is Canada hopeless?

I don’t know. The meteoric rise in Canadian subway construction costs in the last 15 years has ensured expansion will soon grind to a halt. Much of this rise comes from reforms that the Anglosphere has convinced itself improve outcomes, like design-build and reliance on outside consultants; in that sense, the US hasn’t been copying Canada, but instead Canada has been copying the US and getting American results.

That said, two positive aspects are notable. The first is very high housing and commercial growth in the most desirable cities, if not in their most exclusive neighborhoods. Vancouver probably has another 10-20 years before its developable housing reserves near existing SkyTrain run out and it is forced to figure out how to affordably expand the network. Nowhere in Europe is housing growth as fast as in Metro Vancouver; among the cities for which I have data, only Stockholm comes close, growing at 7-8 net units per 1,000 people annually.

Moreover, with Downtown Vancouver increasingly built out, Vancouver seems to be successfully expanding the CBD outward: Central Broadway already has many jobs and will most likely have further commercial growth as the Millennium Line is extended there. Thus, employers that don’t fit into the Downtown Vancouver peninsula should find a home close enough for SkyTrain, rather than hopping to suburban office parks as in the US. Right now, the central blob of 100 km^2 – a metric I use purely because of limitations on French and Canadian data granularity – has a little more than 30% of area jobs in Vancouver, comparable to Paris, Lyon, New York, Boston, and San Francisco, and ahead of other American cities.

The second aspect is that Canadians are collectively a somewhat more internationally curious nation than Americans. They are more American than European, but the experience of living in a different country from the United States makes it easier for them to absorb foreign knowledge. The reaction to my and Jonathan English’s August article about Canadian costs has been sympathetic, with serious people with some power in Toronto contacting Jonathan to figure out how Canada can improve. The reaction I have received within the United States runs the gamut – some agencies are genuinely helpful and realize that they’ll be better off if we can come up with a recipe for reducing costs, others prefer to obstruct and stonewall.

My perception of Canadian politics is that even right-populists like Doug Ford are more serious about this than most American electeds. In that sense, Ford is much like Boris Johnson, who could move to Massachusetts to be viceroy and far improve governance in both Britain and Massachusetts. My suspicion is that this is linked to Canada’s relatively transit-oriented past and present: broad swaths of the Ontarian middle class ride trains, as is the case in Outer London and the suburbs of Paris. A large bloc of present-day swing voters who use public transport is a good political guarantee of positive attention to public transport in the future. American cities don’t have that – there are no competitive partisan elections anywhere with some semblance of public transportation.

These two points of hope are solid but still run against powerful currents. Toronto really is botching the RER project because of insider obstruction and timidity, and without a strong RER project there is no way to extend public transportation to the suburbs. Vancouver is incapable of concentrating resources where they do the most good. And all Canadian cities have seen an explosion in costs. Canadians increasingly understand the cost problem, but it remains to be seen whether they can fix it.

New York City Zoning and Subway Capacity

I got a bunch of accolades and a bunch of flaming replies over a tweetstorm imagining a bigger, better New York. Some people complained about my claim that subway trains in Brooklyn are underfull; I urge everyone to read my analysis of data from 2016 – it’s still relevant today, as the only big change is that Second Avenue Subway has reduced Upper East Side crowding. The point of this post is to demonstrate where zoning should definitely focus on adding more apartments, to fill trains that are not yet full.

The map

Instead of using the current subway map, let us start with a deinterlined map:

The reason for using this map is that it’s cleaner than the real map, since there is no track-sharing between routes of different colors, and not much route-sharing (one color local, one express). Getting from here to this map is cheap but not free, as it requires certain junction rebuilds, especially on the 2/3. I ask that my commenters resist the temptation to argue over the details of this map, since the point about zoned capacity does not really depend on questions like whether the E runs local in Queens and the F runs express or the reverse.

Where there is capacity

In 2016, three directions on the subway were truly at capacity, surpassing 4 standees per square meter: the 2/3 and 4/5 coming into Midtown from Uptown, and the L. The analysis looks at crowding on trains entering the Manhattan core, so it lumps lines from Queens based on which tunnel they enter from, which underestimates crowding on the E, since it shares tracks with the under-capacity M. Counted properly, the express Queens Boulevard trains should be viewed as near or at capacity as well, the F having 3.33 standees per square meter and the E having somewhat more.

Additional lines with capacity crunches, with about 3 standees per square meter or more, include the A/D coming in from Uptown, the 6, and the Astoria Line (then the N/Q, now the N/W). The 1 and 7 trains have capacity crunches as well in outlying areas: the 7 is overcrowded until it hits the transfer points to the E/F and N/W but has plenty of space in Long Island City, and the 1 is fairly crowded north of the junction with the express trains and then unloads passengers onto the overcrowded 2/3. These areas should not be deemed to have much spare capacity until such time as operations on the subway improve, permitting higher frequency and eventually more lines.

In contrast, the remaining lines have space, often plenty of space. Everything in Brooklyn except the L and to some extent the J/M/Z is underfull: these trains have high frequency as determined by crowding guidelines at the Uptown or Queens end, but in Brooklyn there are fewer people today so the ridership is weaker. The local lines on the Upper West Side both have plenty of space on the trains as well as space on the tracks for more trains if need be. The 7 downstream of Queensboro Plaza has plenty of space, and the local Queens Boulevard trains downstream of Jackson Heights have nowhere for passengers to transfer to an overcrowded express service.

Since I’m relying on data from 2016, there’s no accounting for Second Avenue Subway. Even then, the 4/5 was only the third most overcrowded trunk line entering the Manhattan core, and it’s likely that there’s additional capacity coming from the new line. There’s certainly space on the tracks for more trains on Second Avenue, and one of the goals of deinterlining specifically is to make it feasible to run more service on this line, which currently only runs a train every 6-8 minutes at rush hour.

The map of where New York could add housing

The map excludes parts of Lower and Midtown Manhattan where the highest and best use is commercial rather than residential. But the boundaries there are deliberately crude: Downtown Brooklyn, NYU, and the Meatpacking District are drawn, to avoid excessive fragmentation of the drawn area, while Chelsea and Hell’s Kitchen are excluded as too close to Midtown.

The map also does not look at considerations other than capacity. Some of the highlit areas on the Upper East and West Sides and Lower East Side are already built to very high density, at least on the avenues and major streets; these areas should be the template of how the rest of the city should look. At the other end, East New York has too weak demand for massive construction, especially if everything to its west is upzoned.

However, large swaths of desirable, close-in areas with relatively short buildings are highlit. Rich inner Brooklyn neighborhoods like Park Slope and South Brooklyn are currently built to missing middle density, with a floor area ratio of about 1.5 away from corner lots. A more appropriate floor area ratio in these neighborhoods is 12, corresponding to tapering buildings in the 20-30 story range, as on the avenues on the Upper East and West Sides. Park Slope is half an hour from Midtown by subway, and less than that from Lower Manhattan. The population of these neighborhoods is perhaps 150,000, and should be more than a million given their proximity to job centers.

Subway deserts and future additions

The map is designed to work with more or less the same service as today, maybe with slightly more frequency on lines that could handle it easily (that is, Second Avenue Subway). But what about future service? The L train is overcrowded, but only runs 19 trains per hour at the peak due to electrical limitations, and could go up to 26 with better electrical capacity, or for that matter lighter trains drawing less power during acceleration. Further extensions of Second Avenue Subway could more effectively relieve pressure off the 4/5, to the point of creating more capacity in the Bronx, which remains well below peak population. Commuter rail modernization opens up large swaths of Queens. Decades in the making extensions on Nostrand and Utica fill in the transit desert in southeast Brooklyn, currently served by buses that nominally come every 2 minutes and in practice comes in platoons of 4 every 8 minutes.

As with the map above, a hypothetical map of development sites assuming reasonable subway expansion includes areas that would be unlikely to actually see new development. Williamsburg and Greenpoint may turn into forests of towers given the opportunity, but in neighborhoods like Sheepshead Bay and East Flatbush developers might well stick to the occasional 6-to-10-story mid-rise building that would not look out of place in Paris. In Eastern Queens, the desired density is probably spiky, with clusters of tall buildings around LIRR stations surrounded by single-family houses and missing middle, much like the structure of density in Toronto and Vancouver.

Small is not Resilient

I wrote about how the future is not retro, and Daniel Herriges Strong Towns just responded, saying that traditional development is timeless. I urge all readers to click the last link and read the article, which makes some good points about how cars hollowed out what both Daniel and I call the traditional prewar Midwestern town. There are really two big flaws in the piece. First, it makes some claims about inequality and segregation that are true in American cities but false in the example I give for spiky development, Vancouver. And second, it brings up the resilience of the traditional small town. It’s the second point that I wish to contest: small is not resilient, and moreover, as the economy and society evolve, the minimum size required for resilience rises.

Small cities in the 2010s

In the premodern era, a city of 50,000 was a bustling metropolis. In 1900, it was still a sizable city. In 2019, it is small. The difference is partly relative: a migrant to the big city had the option of moving to a few 200,000 cities in 1900 and one of about ten 1,000,000+ cities, whereas today the same migrant can move to many metro areas with millions of people. But part of it has to do with changes in the economy.

In Adam Smith’s day, big businesses were rare. If you had five employees, you were a big employer. Then came the factory system and firm size grew, but even then companies were small by the standards of today’s specialized economy. A city of 50,000 might well specialize in a single product, as was common in the American manufacturing belt (Krugman mentions this on pp. 11-12 here), but there would be many factories each with a few hundred employees.

But as the economy grows more complex, firm size grows, and so does the interdependence between different firms in the same supply chain. Moreover, the support functions within a city grow in complexity: schools, a hospital, logistics, retail, and so on. The proportion of the population employed in the core factory is lower, as the factory’s high productivity supports more non-manufacturing employees. The upshot is that it’s easy for a town of 50,000 to live off of a single firm and its supply chain. This is not resilient: if the firm fails, the town dies.

Occasionally, cities of that size can have more resilience. Perhaps they’re suburbs of a larger city, in which case they live off of commuting to a more diverse economic center. Perhaps they happen to live off of an industry that cannot die so easily, such as a state capital or a university. On social media one of my followers brought up farming as an example of an activity whose towns have held up in the Midwest better than manufacturing towns; farming is in fact extremely risky, but it has been subsidized since the 1930s, so it has some resilience thanks to subsidies from more internally resilient parts of the country.

Large cities and resilience

I read Ed Glaeser not so much for his observations about the housing market – he’s a lot of things but he’s not a housing economist – as for his economic history. He has a pair of excellent papers describing the economic histories of Boston and New York respectively. Boston, he argues, has reinvented itself three times in the last 200 years after declining, using its high education levels to move up the value chain. New York was never in decline except in the 1970s, and has resiled from its 1980 low as well.

These as well as other large cities have economic diversity that small cities could never hope to have. At the time Glaeser wrote his paper about New York, in 2005, the city seemed dominated by finance and related industries. And yet in the 2007-9 recession, which disproportionately hit finance, the metro area’s per capita income relative to the national average barely budged, falling from 135.3% to 133.8%; in 2017 it was up to 137.5%. The New York region is a center of finance, yes, but it’s also a center of media, academic research, biotech, and increasingly software.

New York is extremely large, and has large clusters in many industries, as do London, Paris, Tokyo, and other megacities. But even medium-size cities often have several clusters, if not so many. This is especially evident in Germany, where Munich, Hamburg, Stuttgart, and Frankfurt are not particularly large. Munich is the center of conglomerates in a variety of industries, including cars (BMW, far and away the largest employer, but also MAN), general industry (Siemens), chemicals (Linde), and finance (Allianz).

What’s true is that these large cities have much more knowledge work than menial work – yes, even Munich, much more a center of engineering than of menial production. But the future is not retro in the mix of jobs any more than it is in its urban layout. The nostalgics of the middle of the 20th century taxed productive industrial cities to subsidize farmers, treating industrial work as the domain of socialists, Jews, immigrants, and other weirdos; the nostalgics of the early 21st century propose to tax productive knowledge economies to subsidize menial workers, and in some specific cases, like American protection of its auto industry, this has been the case for decades.

Small cities as suburbs

In Germany, Switzerland, and the Netherlands, unlike in the United States or France, there is a vigorous tradition of historic small cities becoming suburbs of larger cities while retaining their identity. This doesn’t really involve any of Strong Towns’ bêtes noires about roads and streets – in fact pretty much all of these cities have extensive sprawl with big box retail and near-universal car ownership. Rather, they have tight links with larger urban cores via regional rail networks, and German zoning is less strict about commercialization of near-center residential areas than American zoning. There was also no history of white flight in these areas – the white flight in Germany is in the cores of very large cities, like Berlin, which can replace fleeing whites one to one with immigrants.

In this sense, various Rhineland cities like Worms and Speyer do better than Midwestern cities of the same size. But even though they maintain their historic identities, they are not truly economically independent. In that sense, a better American analogy would be various cities in New England and the mid-Atlantic that have fallen into the megalopolis’s orbit, such as Salem, Worcester, Providence, Worcester, New Brunswick, and Wilmington. Many of these are poor because of the legacy of suburbanization and white flight, but their built-up areas aren’t so poor.

However, the most important link between such small cities and larger urban core, the regional railway, heavily encourages spiky development. In Providence, developers readily build mid-rise housing right next to Providence Station. If the quality of regional rail to Boston improves, they will presumably be willing to build even more, potentially going taller, or slightly farther from the station. Elsewhere in the city, rents are not high enough to justify much new construction, and Downcity is so weak that the tallest building, the Superman Building, is empty. In effect, Providence’s future economic value is as part of the Boston region.

The relatively even development of past generations is of less use in such a city. The economy of a Providence or a Wilmington is not strong enough that everyone can work in the city and earn a good wage. If the most important destination is a distant core like Boston or Philadelphia, then people will seek locations right near the train station. Driving is not by itself useful – why drive an hour from Rhode Island when cheaper suburbs are available within half an hour? Connecting from local transit would be feasible if the interchange were as tightly timed and integrated as in Germany, but even then this system would be oriented around one dot – the train station – rather than a larger walkable downtown area.

A bigger city is a better city

Resilience in the sense of being able to withstand economic shocks requires a measure of economic diversity. This has always been easier in larger cities than in smaller ones. Moreover, over time there is size category creep: the size that would classify a city a hundred years ago as large barely qualifies it to be medium-size today, especially in a large continental superpower like the US. As global economic complexity increases, the size of businesses and their dedicated supply chains as well as local multipliers rises. The city size that was perfectly resilient in an economy with a GDP per capita of $15,000 is fragile in an economy with a GDP per capita of $60,000.

Usually, the absolute richest or more successful places may not be so big. There are hundreds of American metro areas, so a priori there is no reason for New York to be at the top, just as there is no reason for it to be at the bottom. Nonetheless, the fact that larger cities are consistently richer as well as at less risk of decline than smaller cities – New York is one of the richest metro areas, just not the single richest – should give people who think small is beautiful pause.

Whatever one’s aesthetic judgment about the beauty of the upper Mississippi versus that of the lower Hudson, the economic and social system of very large places weathers crises better, and produces more consistent prosperity. Economically and socially, a bigger city is a better city, and national development policy should reject nostalgia and make it possible for developers to build where there is demand – that is, in the richest, most populated metro areas, enabling these regions to grow further by infill as well as accretion. Just as 50,000 was fine in 1900 but isn’t today, a million is fine today but may not be in 2100, and it’s important to enable larger cities to form where people want to live and open businesses.

The Future is not Retro

One faction of urbanists that I’ve sometimes found myself clashing with is people who assume that a greener, less auto-centric future will look something like the traditional small towns of the past. Strong Towns is the best example I know of of this tendency, arguing against high-rise urban redevelopment and in favor of urbanism that looks like pre-freeway Midwestern main streets. But this retro attitude to the future happens everywhere, and recently I’ve had to argue about this with the generally pro-modern Cap’n Transit and his take about the future of vacations. Even the push for light rail in a number of cities has connections with nostalgia for old streetcars, to the point that some American cities build mixed-traffic streetcars, such as Portland.

The future was not retro in the 1950s

The best analogy for a zero-emissions future is ironically what it seeks to undo: the history of suburbanization. In retrospect, we can view midcentury suburbanization as a physical expansion of built-up areas at lower density, at automobile scale. But at the time, it was not always viewed this way. Socially, the suburbs were supposed to be a return to rural virtues. The American patrician reformers who advocated for them consciously wanted to get rid of ethnic urban neighborhoods and their alien cultures. The German Christian democratic push for regional road and rail connections has the same social origin, just without the ethnic dimension – cities were dens of iniquity and sin.

At the same time, the suburbs, that future of the middle of the 20th century, were completely different from the mythologized 19th century past, before cities like New York and Berlin had grown so big. Most obviously, they were linked to urban jobs; the social forces that pushed for them were aware of that in real time, and sought transportation links precisely in order to permit access to urban jobs in what they hoped would be rural living.

But a number of other key differences are visible – for one, those suburbs were near the big cities of the early 20th century, and not in areas with demographic decline. In the United States, the Great Plains and Appalachia kept depopulating and the Deep South except Atlanta kept demographically stagnating. The growth in that era of interregional convergence happened in suburbs around New York, Chicago, and other big then-industrial cities, and in parts of what would soon be called the Sunbelt, namely Southern California, Texas, and Florida. In Germany, this history is more complicated, as the stagnating region that traditionalists had hoped to repopulate was Prussia and Posen, which were given to Poland at the end of the war and ethnically cleansed of their German populations. However, we can still see postwar shifts within West Germany toward suburbs of big cities like Munich and Frankfurt, while the Ruhr stagnated.

The future of transit-oriented development is not retro

People who dislike the auto-oriented form of cities can easily romanticize how cities looked before mass motorization. They’d have uniform missing middle built form in most of the US and UK, or uniform mid-rise in New York and Continental Europe. American YIMBYs in particular easily slip into romanticizing missing middle density and asking to replace single-family housing with duplexes and triplexes rather than with anything more substantial.

If you want to see what 21st-century TOD looks like, go to the richer parts of East Asia, especially Tokyo, which builds much more housing than Hong Kong and Singapore. The density in Tokyo is anything but uniform. There are clusters of high-rise buildings next to train stations, and lower density further away, even small single-family houses fronting narrow streets far enough from train stations that it’s not economical to redevelop them. It offends nostalgic Westerners; the future often does.

In the context of a growing city like New York or London, what this means is that the suburbs can expect to look spiky. There’s no point in turning, say, everything within two kilometers of Cockfosters (or the Little Neck LIRR station) into mid-rise apartments or even rowhouses. What’s the point? There’s a lot more demand 100 meters from the station than two kilometers away, enough that people pay the construction cost premium for the 20th floor 100 meters from the stations in preference to the third floor two kilometers away. The same is true for Paris – there’s no solution for its growth needs other than high-rises near RER stations and key Metro stations in the city as well as the suburbs, like the existing social housing complexes but with less space between buildings. It may offend people who associate high-rises with either the poor or recent high-skill immigrants, but again, the future often offends traditionalists.

The future of transportation is not retro

In countries that do not rigidly prevent urban housing growth the way the US does, the trend toward reurbanization is clear. Germany’s big cities are growing while everything else is shrinking save some suburbs in the richest regions, such as around Munich. Rural France keeps depopulating.

In this context, the modes of transportation of the future are rapid transit and high-speed rail. Rapid transit is preferable to buses and surface trains in most cities, because it serves spiky development better – the stations are spaced farther apart, which is fine because population density is not isotropic and neither is job density, and larger cities need the longer range that comes with the higher average speed of the subway or regional train over that of the tramway.

High-speed rail is likewise preferable to an everywhere-to-everywhere low-speed rail network like that of Switzerland. In a country with very large metro areas spaced 500 km or so apart, like the US, France, or Germany, connecting those growing city centers is of crucial importance, while nearby cities of 100,000 are of diminishing importance. Moreover, very big cities can be connected by trains so frequent that untimed transfers are viable. Already under the Deutschlandtakt plan, there will be 2.5 trains between Berlin and Hanover every hour, and if average speeds between Berlin and the Rhine-Ruhr were increased to be in line with those of the TGVs, demand would fill 4-6 trains per hour, enough to facilitate untimed transfers from connecting lines going north and south of Hanover. The Northeast Corridor has even more latent demand, given the huge size of New York.

The future of travel is not retro

The transportation network both follows and shapes travel patterns. Rapid transit is symbiotic with spiky TOD, and high-speed rail is symbiotic with extensive intercity travel.

The implication is that the future of holidays, too, is not retro. Vacation trips between major cities will become easier if countries that are not France and Japan build a dense network of high-speed lines akin to what France has done over the last 40 years and what Japan has done over the last 60. Many of those cities have thriving tourism economies, and these can expect to expand if there are fast trains connecting them to other cities within 300-1,000 kilometers.

Sometimes, these high-speed lines could serve romanticized tourist destinations. Niagara Falls lies between New York and Toronto, and could see expansion of visits, including day trips from Toronto and Buffalo and overnight stays from New York. The Riviera will surely see more travel once the much-delayed LGV PACA puts Nice four hours away from Paris by train rather than five and a half. Even the Black Forest might see an expansion of travel if people connect from high-speed trains from the rest of Germany to regional trains at Freiburg, going from the Rhine Valley up to the mountains; but even then, I expect a future Germany’s domestic tourism to be increasingly urban, probably involving the Rhine waterfront as well as the historic cities along the river.

But for the most part, tourist destinations designed around driving, like most American national parks as well as state parks like the Catskills, will shrink in importance in a zero-carbon future. It does not matter if they used to have rail access, as Glacier National Park did; the tourism of the leisure class of the early 20th century is not the same as that of the middle class of the middle of the 21st. Grand Canyon and Yellowstone are not the only pretty places in the world or even in the United States; the Hudson Valley and the entire Pacific Coast are pretty too, and do not require either driving or taking a hypothetical train line that, on the list of the United States’ top transportation priorities, would not crack the top 100. This will offend people whose idea of environmentalism is based on the priorities of turn-of-the-century patrician conservationists, but environmental science has moved on and the nature of the biggest ecological crisis facing humanity has changed.

The non-retro future is pretty cool

The theme of the future is that, just as the Industrial Revolution involved urbanization and rural depopulation, urban development patterns this century involve growth in the big metro areas and decline elsewhere and in traditional small towns. This is fine. The status anxieties of Basil Fawlty types who either can’t or won’t adapt to a world that has little use for their prejudices are not a serious public concern.

Already, people lead full lives in big global cities like New York and London without any of the trappings of what passed for normality in the middle of the 20th century, like a detached house with a yard and no racial minorities or working-class people within sight. The rest will adapt to this reality, just as early 20th century urbanites adapted to the reality of suburbanization a generation later.

It’s not even an imposition. It’s opportunity. People can live in high-quality housing with access to extensive social as well as job networks, and travel to many different places with different languages, flora and fauna, vistas, architecture, food, and local retail. Even in the same language zone, Northern and Southern Germany look completely different from each other, as do Paris and Southern France, or New England and Washington. Then outside the cities there are enough places walking distance from a commuter rail line or on the way on a high-speed line between two cities that people can if they’d like go somewhere and spend time out of sight of other people. There’s so much to do in a regime of green prosperity; the world merely awaits the enactment of policies that encourage such a future in lieu of one dominated by small-minded local interests who define themselves by how much they can pollute.

Teacher Housing and the Rot

I recently saw that San Francisco is considering fast-tracking residential development dedicated to teacher housing. There are quibbles between the moderate mayor and the progressives on city council (“Board of Supervisors”) over the exact structure of the housing subsidies, but both sides agree at least in theory that it should be easier to build housing for teachers; for more background, see article here and Twitter back-and-forth here. I bring this up because it’s an example of bad governance at the local level in the US, one that sends everyone the message, “you should get more clout to bribe politicians.”

The basic problem is that market-rate housing in San Francisco is extremely expensive; in the Mission, a two-bedroom apartment rents for about $5,000 or $5,500 a month. There’s rent control, but it requires one to have lived in the city for a very long time – friends who have lived in the city since the mid-2000s pay around $2,700, which is borderline on a teacher’s salary. Usually the city’s local notables don’t have to care about whether housing is affordable to people in intermediate professions, since our rent is their property values, but “teachers can’t afford housing here” could be a rallying cry for more housing. Thus, they feel like making an exception.

Making an exception is the hallmark of populist governance. In a system with not much rule of law and no trust that there will ever be rule of law, people don’t ask for better rules but to benefit from exceptions. That various exporters threatened to leave Britain over Brexit did not faze Theresa May – every time a company people didn’t hate made such a threat, she offered special subsidies to stay no matter what would happen with the trade agreement with the rump-EU.

The problem with populism is that it sends the message, invest in political marketing and not in productivity. A company that sees that San Francisco is subsidizing housing for teachers in preference to other workers with similar pay and skill level – clerical workers, social workers, lab techs – gets a clear incentive to give its workers more political prestige through political contributions, sponsorships of events the local politicians are interested in, etc. It faces less pressure to invest in its productivity and pay its workers better, since housing is not allocated by market pricing but by political whims.

Under liberal governance, if San Francisco wishes to give its teachers perks, it can pay them better. Programmers get paid $110,000 a year plus benefits (stock options, good health insurance, free food), and the city can if it wants raise taxes and pay teachers similarly; if it can commit to maintaining such high pay indefinitely it can ensure the profession will get more prestige and attract people who otherwise would be writing code for how to sell user data to advertisers slightly more efficiently.

However, a tax hike might fall on the local homeowners and on other rich people who have invested a lot of time and money in obtaining political influence. To avoid burdening the powerful, the city can’t do this – it has to come up with some one-off bespoke deal for teacher housing, rather than permitting more housing across the board and also raising salaries to be competitive with those of the private sector.

Improving the quality of governance requires making it harder for politicians to create such deals. The original YIMBY praxis of state preemption laws is one way to do this: it completely takes local notables out of the loop. While the YIMBY groups on the ground in California don’t go further with this, their favorite state politician, Scott Wiener, who represents San Francisco in the State Senate, is consciously trying to form an informal state party with some ideological coherence based on relevant state issues, led by the question of housing.

It may be prudent to refine this preemption doctrine by interfering with local rules that favor some groups over others in housing. Thus the state should pass a preemption law that forbids dedicated housing for teachers, cops, or other charismatic professions, and requires all housing to be allocated by market pricing, or, failing that, by a clear process of rent control, such as waitlists or income limits. Private actors may continue to buy and sell housing based on their wishes, subject to the usual anti-discrimination law, but municipalities may not use incentives such as subsidies, tax breaks, access to public land, or special fast-tracking of approvals. Such a law may well succeed in the state legislature – unlike the SB 50 process preempting zoning restrictions, this law would not be nakedly offensive to the privileged group of suburban homeowners who managed to scuttle SB 50.

It is not really possible to develop rule of law in an environment in which powerful people can easily circumvent the rules. A city that can offer a way out of an onerous permitting regime to people who make it attractive offers – that is, bribery – has no incentive to make the permitting regime easier, and a powerful incentive to keep it as it is. If building housing becomes easier, politicians lose the ability to extort community benefits by threatening to withhold permits. And if there is a way out for socioeconomic classes that demagogues can’t dismiss as gentrifiers, transients, and rootless cosmopolitans, then politicians gain the ability to threaten everyone else, while employers as well as nonprofits get a powerful message that they should pay more bribes. It’s a win-win for everyone except the hapless residents governed by such corruption.

The question is whether area YIMBYs are willing to leverage the one point of power they do have – namely, their connection to nationwide ideological networks that the local notables of these cities pay lip service to. Out of four New York Times op-ed writers who online liberals like, two (Paul Krugman, Jamelle Bouie) have openly called for more housing in cities, and two (Charles Blow, Michelle Goldberg) have never opined on this issue; NIMBYs have ample local power but little national clout. YIMBYs have this advantage and need to press it to completely sideline machine politics and personality politics – that is, to form a coherent, identifiable political party in California (or New York, or Massachusetts) contesting state and local elections, and if winning local elections without assimilating to the local rot is not possible then work to delegitimize government below the state level as irredeemably corrupt.

Job Centralization in the City

The table below collates job centralization not by CBD as in this post but by central city. Parisian data comes from INSEE, here and here; American data comes from Wikipedia for population and OnTheMap for job counts. In general, I tried making the central city definition about 18% of the metro area to be comparable with Paris, but there is still a lot of variation, so this table should absolutely not be read as a ranking of metro areas by job centralization.

Metro area Population Jobs Central city Central pop’n Central jobs Central job share
Ile-de-France 12,082,144 5,682,048 Paris 2,206,488 1,797,745 31.6%

The Sunbelt

There appears to be a fair amount of job centralization in the Sunbelt cities, right? In Metro Atlanta, Fulton County has a slightly higher proportion of regional jobs than Paris with a slightly lower share of residential population.

But actually, no. Absolute densities matter in addition to relative centralization of jobs versus residences. In Houston and Los Angeles the central areas are drawn to encircle the downtown and near-downtown job centers – both cities preferentially annex suburban job sites so using municipal boundaries is not useful. A hefty share of area jobs are in these centers, especially in Houston. But ultimately it’s still not a lot of jobs in a very large land area, around 300 square kilometers for both, compared with 100 for the city of Paris or for San Francisco. Fulton County is vast, and the jobs are distributed all over Atlanta and its northern suburbs within the county.

Houston is a particularly good example of monocentrism with a weak center. There are not a lot of strong suburban job centers in Houston – nothing like Silicon Valley, Downtown Newark, the Route 128 corridor, La Defense, Burbank, or Tysons Corner. The city itself has about two thirds of area jobs, thanks to selective annexations. But the share of the CBD in area jobs is low, just 150,000 jobs in the 45/69/10 beltway, or 5.3% of area jobs. Outside the CBD job density plummets, as the outlying job centers making the difference between 5.3% and 26.9% are located at haphazard locations all over 610.

Older American cities

The extent of centralization in the Northeast, Chicago, and San Francisco is greater. New York in particular is a lot like Paris, with about a third of area jobs in a high-density contiguous blob consisting of less than one fifth of regional population. It has nothing like La Defense in the suburbs, but its suburban job centers, while much smaller, include some recognizably dense ones, especially Newark and the Jersey City waterfront. One needs to go well into suburbia to see the difference between Paris, where the suburbs have a structure of density with mid- and high-rise residential development as well as offices next to train stations, and New York, where the job centers in farther-out suburbia, like Central Jersey, have no such structure and are located exclusively based on auto access.

Boston, Washington, and San Francisco all have varying degrees of centralization. I mentioned last year that Boston is increasingly an example of European-style job sprawl, in which jobs spill over from the CBD to nearby areas rather than to faraway office parks. New York has long had such spillover – Long Island City is such a job center, and may at this point have more jobs than Downtown Brooklyn; the Jersey City waterfront is another such example, as is the growth of the Meatpacking District around Google. In Boston the equivalents are Kendall Square and the Seaport; in San Francisco it’s SoMa; in Washington it’s jobs in Arlington around the Orange Line, where older TOD was residential.

Chicago and Philadelphia are the least centralized. Chicago has a well-defined supertall skyline with about 500,000 people working in or near the Loop. But outside that central area, job density craters. Chicago’s share of metro area jobs is about 1.5% higher than its share of metro population, and if we remove the airport, surrounded by suburbia, this difference drops to 0.5%. Philadelphia’s share of metro area jobs is actually lower than its share of metro area population by 1.5%. In these regions, if you’re not working in city center, you’re working at an office park in a middle-class-to-rich suburb built without regard for the area’s vast legacy mainline rail network.
