Counties with the largest numeric growth are all located in the south and the west, with counties in Texas taking four out of the top 10 spots according to new U.S. Census Bureau population estimates released today. By metropolitan area, Dallas-Fort Worth-Arlington, Texas, had the largest numeric growth with a gain of 131,767 (1.8 percent) in 2018, followed by Phoenix-Mesa-Scottsdale, Ariz. with an increase of 96,268 (2.0 percent). Migration, both domestic and international, as well as natural increase contributed to the growth in each of these areas, with natural increase serving as the largest source of population growth in Dallas and domestic migration serving as the largest source in Phoenix.
“One interesting trend we are seeing this year is that metro areas not among the most populous are ranked in the top 10 for population growth,” said Sandra Johnson, a demographer in the Census Bureau’s Population Division. “Though no new metro areas moved into the top 10 largest areas, Phoenix, Seattle, Austin, and Orlando all experienced numeric increases in population since 2010, rivaling growth in areas with much larger populations. This trend is consistent with the overall growth we are seeing in the south and the west.”
