For many urban planners and new urbanists, the U.S. census numbers released in 2010 were demoralizing.
They had anticipated that Americans, after decades of fleeing to suburbs, would reverse that trend in the 2000s and begin returning to rebuilt cities. Instead, suburban growth increased. According to New Geography, 91 percent of growth over the decade occurred in suburbs, an increase from the 1990-2000 timespan in which 85 percent occurred in suburbs.
But there is one kernel of optimism in the numbers for city lovers: some urban cores are growing.
Writing for New Geography last week, Aaron M. Renn says in some cities “we see that over the 2000s out-migration from the core to the suburban counties was relatively flat or even declined late in the decade as general mobility declined in the Great Recession. In contrast, migration from the suburban counties to the core stayed flat or actually increased.”
