Inequality & Mass Transit in the Bay Area

A recent feature in The New Yorker juxtaposed New York City's subway stops with their residents' incomes. Like NYC, San Francisco has people of both extreme poverty and wealth, often living toe-to-toe. We wondered how those graphs would look in our neck of the woods. The results show the Bay Area's economic inequality and its relationship with transit and urban form.

Stop and route information came from their respective agencies' GTFS feeds. Income data was gathered from the 2010 US Census, via their API, using verbatim the value from the single census tract where each stop is located.

In some instances, the stops lie on the boundaries of different tracts, and an improved model might produce a weighted average of all the tracts each stop serves.
