There are workplaces where most employees are high-income, for example office towers (or office parks) hosting tech firms, law firms, or banks. There are workplaces where most employees are working-class, for example factories, warehouses, and farms. Does this lead to a difference in commuting patterns by class? I fired up OnTheMap two days ago and investigated. This is American data, so it stratifies workers by income, education, industry, or race rather than by job class. I generated maps for New York and saw the following:
There are three income classes available, and I looked at the bottom and top ones, but the middle one, still skewed toward the working class, looks the same as the bottom class. The biggest observation is that Midtown is dominant regardless of income, but is more dominant for middle-class workers (more than $40,000 a year) than for low-income ones (up to $15,000, or for that matter $15,000-40,000).
The colors are relative, and the deepest shade of blue represents much more density for middle-class workers, even taking into account the fact that they outnumber under-$15,000 workers almost four to one. Among the lowest-income workers we see more work on Queens Boulevard and in Williamsburg, Flushing, and the Hub, but these remain tertiary workplaces at most. The only place outside Midtown, Lower Manhattan, or Downtown Brooklyn (which includes all city workers in Brooklyn due to how the tool works, so it looks denser than it is) that has even the third out of five colors for low-income workers is Columbia, where the low-income job density is one-third that of Midtown, and where there is also a concentration of middle-class workers.
The same pattern – job centers are basically the same, but there’s more concentration within the CBD for the rich – also appears if we look at individual neighborhoods. Here is the Upper East Side versus East Harlem:
I chose these two neighborhoods to compare because they exhibit very large differences in average income and are on the same subway line. Potentially there could be a difference between where East Siders and West Siders work due to the difficulty of crosstown commuting, so I thought it would be best to compare different socioeconomic classes of people on the same line. With the East Side-only restriction, we see two Uptown job centers eclipse Columbia: Weill-Cornell Medical Center in Lenox Hill at the southeast corner of the Upper East Side, and Mount Sinai Hospital at the northwest corner.
One place where there is a bigger difference is the definition of Midtown. Looking at the general job distribution I’d always defined Midtown to range between 34th and 59th Street. However, there are noticeable differences by income:
For the middle class, Midtown ranges from 34th to 57th Street and peaks around 47th. For the lowest-income workers, it ranges from 28th to 49th and peaks in the high 30s. My best explanation for this is that Midtown South and Union Square are more retail hubs than office hubs, featuring department stores and shopping centers, where the rich spend money rather than earning it.
In a deindustrialized country like the US or France, the working class no longer works in manufacturing or logistics. There are a lot of truck drivers today – 3.5 million in the US – but in 1920 the American railroad industry peaked at 2.1 million employees (source, PDF-p. 15), nine times today’s total, in a country with one third the population it has today and much less mobility. Manufacturing has plummeted as a share of employment, and is decreasing even in industrial exporters like Germany and Sweden. Instead, most poor people work at places that also employ many high-skill, high-income workers, such as hospitals and universities, or at places where they serve high-income consumption, such as retail and airports.
Since the working class works right next to the middle class, the nature of bosses’ demands of workers has also changed. Low-skill works now involves far more emotional labor; in Singapore, which makes the modern-day boss-worker relationships more explicit than the Anglosphere proper, there are signs all over the airport reminding workers to smile more. Nobody cares if auto workers smile, but they’re no longer a large fraction of the working class.
With the working class employed right next to the middle class, there is also less difference in commuting. For the most part, the same transportation services that serve middle-class jobs also serve working-class jobs and vice versa. This remains true even across racially segregated communities. The patterns of white New York employment are similar to those of middle-class New York employment, and those of black, Hispanic, and Asian employment are similar to those of the working class, with small differences (Asians are somewhat more concentrated in Flushing, and blacks in Downtown Brooklyn, reflecting the fact that blacks are overrepresented in public employment in the US and all city workers in Brooklyn are counted at Court Square).
This is true provided that opportunities for transportation are available without class segregation. This is not the situation in New York today. Commuter rail actually serves working-class jobs better than middle-class jobs, since Penn Station is closer to the department stores of 34th Street than to the office towers in the 50s. However, it’s priced for the middle class, forcing the working class to take slower buses and subway trains.
When I posted the above maps on Twitter, Stephen Smith chimed in saying that, look, the poor are less likely to work in the CBD than the middle class, so everywhere-to-everywhere public transportation is especially useful for them. While Stephen’s conclusion is correct, it is not supported by this specific data. In the $40,000 and up category, 57% of city jobs are in Manhattan south of 60th Street, compared with 37% in the $15,000-40,000 and under-$15,000 categories. It’s a noticeable difference, but not an enormous one. The reason Stephen is correct about how rides crosstown transit is different: people who can afford cars are very likely to drive if the transit option is not good (which it isn’t today), whereas people who can’t are stuck riding slow crosstown buses; in contrast, for CBD-bound commutes, the subway and commuter rail work reasonably well (especially at rush hour) and driving is awful.
Instead of trying to look specifically at low-income and middle- and high-income job centers, it’s better to just plan transit based on general commute patterns, and let anyone take any train or bus. This doesn’t mean business as usual, since it requires transitioning to full fare integration. Nor does this mean ignoring residential segregation by income, which in some cases can lead to transit segregation even in the face of fare integration (for example, the crosstown buses between the Upper East Side and Upper West Side have mostly white, mostly middle-class riders). Finally, this doesn’t mean relying on middle-class transit use patterns as a universal use case, since the middle class drives in the off-hours or to off-CBD locations; it means that relying on middle-class transportation needs could be reasonable. It just means that the rich and poor have substantially the same destinations.
An even bigger implication relates to questions of redevelopment. There have been periodic complaints from the left about gentrification of jobs, in which working-class job sites are turned over to high-end office and retail complexes. For example, Canary Wharf used to be the West India Docks. In New York, Jane Jacobs’ last piece of writing before she died was a criticism of Greenpoint rezoning, in which she specifically talked up the importance of keeping industrial jobs for the working class. But since the big deindustrialization wave, developments brought about by urban renewal, gentrification, and industrial redevelopment have not had any bias against providing employment for the poor. It’s not the factory jobs that the unionized working class still culturally defines itself by, but it’s industries that are hungry for low-skill work, and in many cases are serious target of unionization drives (such as universities).
