Forbes as follows:
From 2009-11, Americans seemed to be clustering again in dense cities, to the great excitement of urban boosters. The recently released 2015 Census population estimates confirm that was an anomaly.
Americans have strongly returned to their decades long pattern of greater suburbanization and migration to lower-density, lower-cost metropolitan areas, largely in the South, Intermountain West and, most of all, in Texas.
The South, Intermountain West and Texas include 6 of the 9 states with no state income tax (counting SD as "intermountain"). That factor is a draw, particularly for retirees.
