Researchers Robert Hibberd and Arthur C. Nelson at the University of Arizona are investigating the jobs-housing balance in transit neighborhoods. They're looking to identify patterns in the way that jobs and housing have concentrated near transit over time.
The paper they'll be presenting at this year's TRB annual meeting specifically looks at Chicago, before and after the great recession of 2008.
In the early 2000s, lower-income jobs were concentrated closest to transit. Higher-income jobs were spreading out to the suburbs, following the sprawl of development. The housing recession of 2008 seems to have caused that pendulum to swing back: from 2009 to 2014, higher-income jobs began crowding into the suddenly more competitive transit-adjacent areas.
