Data and code for: Public transit access and income segregation

Replicates results from "Public transit access and income segregation" (publication forthcoming at International Economic Review).

Article Abstract: What are the implications of mass transit improvements for residential income segregation within cities? I observe large income differences in households’ usage of and residential proximity to ‘fast’ versus ‘slow’ transit (e.g. subways versus buses on shared lanes). Consistent with these observations, I propose a theoretical framework to characterize the relationship between income segregation and the spatial distribution of transit speeds and travel mode choices within cities. I find that transit improvements that would maximize transit ridership tend to reduce income segregation when improving ‘slow’ transit but increase income segregation when improving ‘fast’ transit.
