The Philadelphia story: Age, race, gender and changing travel trends

We find that the travel behavior of young people did not change substantially between 2000 and 2012. Where there are changes, these pale in comparison to the changes among women and black residents. And finally, we find that the built environment factors appear to influence travel more in 2012 than in 2000. Taken together, our findings fit an overarching narrative about urban gentrification and the suburbanization of poverty, rather than a story of Millennials' changing travel behavior.
