Title:

Does Inter-Urban Migration of Immigrants Affect Public Transit Demand?

Abstract:

Residential mobility rates in the U.S. have been in steady decline. Most notably, between 2005 and 2013, one-year intercity migration rate for immigrants has decreased by 0.7 percentage-points, compared to a 0.2 percentage-point decline for the U.S.-born population. Literature on urban implications of geographic mobility suggests that consideration of migration trends, in addition to changes in the characteristics of the resident population, can improve urban transportation demand modelling and forecasting. This research focuses on recent immigrants, a group that contributes, to a large extent, to public transit demand in the U.S. The influence of inter-urban migration rates of recent immigrants on aggregate transit ridership changes across U.S. urban areas between 2008 and 2013 is analyzed, in order to show that changing or declining geographic mobility among recent immigrants can alter future transit demand trends. Migration patterns are derived from the American Community Survey microdata, and transit data is sourced from the U.S. National Transit Database. Findings confirm that inter-urban migration has a separate significant effect on urban transit demand. Results suggest that recent immigrant migrants are less likely to use transit if they arrived from another U.S. metropolitan area than those that have arrived directly from a foreign country. Among domestic migrants, those that move to or arrive from a transit-rich city seem to be more likely to use transit. This paper shows that transportation planners should not treat recent immigrants as a monolithic group. Consideration of their migration patterns, and factors that determine those patterns, can improve planning.
