As Bay Area commuters once again brace for the possibility of a prolonged BART strike and look to alternative transportation means, it seems apropos to feature this innovative multimedia piece: a collection of some of the region’s major public transit lines and the dramatic income disparities that exist among the communities living along those routes.
Created by designers Dan Grover and Michael Belfrage, the interactive project presents a striking landscape of wealth and poverty in the Bay Area, the two extremes often co-existing within a stone’s throw of one another. To show this, they gathered 2010 U.S. Census data on median household incomes and used the value from the specific census tract that each transit stop is located within. One important thing to note when looking at the graphic is that population density is not taken into account, although census tracts typically encompass a population between 2,500 to 8,000 people. Also, because the income data is only for the specific census tract that the stop is located in, it does not represent the median income of an entire city. For instance, the median household income for the Union City BART station is close to $140,00, almost double the median income of that city as a whole. That figure, though, only reflects the small census tract where the station is located (you can see that census tract on this map).
The endeavor was inspired by a similar project published recently on the The New Yorker’s website that juxtaposes New York subway stops with corresponding household income data, showing similarly wide wealth gaps in geographically concentrated areas.
Some interesting takeaways the Bay Area graphic:
- Of BART’s five lines, the Pittsburgh/Bay Point route runs through the widest income gap: in Lafayette, median household income is $153,488, while five stops and 14 miles west, at Oakland’s 12th Street station, it’s a mere $17,349, a disparity of roughly $136,000.
- Of the 19 Muni lines surveyed, the biggest gap in median household income lies along the 1-California bus route, where the difference between highest (California and 30th Ave.) and lowest (Sacramento and Battery) median income stops is nearly $140,000.
- The lowest median income tracts in the Bay Area are generally located near the civic centers of San Francisco and Oakland, in addition to some downtown locales, where the residential population is significantly smaller, homelessness is prevalent and the concentration of single room occupancy housing is often higher.
- On CalTrain, the biggest income gap falls between two neighboring stations less than three miles apart: Redwood City, where median income is just above $30,000, and Atherton, where it’s more than $193,000.
