Jed Kolko: Growth of Suburbs Exceeds Urban Areas

FiveThirtyEight:

The suburbanization of America marches on. Population growth in big cities slowed for the fifth-straight year in 2016,1 according to new census data, while population growth accelerated in the more sprawling counties that surround them.

The Census Bureau on Thursday released population estimates for every one of the more than 3,000 counties in the U.S. I grouped those counties into six categories: urban centers of large metropolitan areas; their densely populated suburbs; their lightly populated suburbs; midsize metros; smaller metro areas; and rural counties, which are outside metro areas entirely.2
The fastest growth was in those lower-density suburbs. Those counties grew by 1.3 percent in 2016, the fastest rate since 2008, when the housing bust put an end to rapid homebuilding in these areas.

An inefficient development pattern keeps chugging along... until it doesn't make sense economically to individual homeowners.
