New U.S. Census Bureau Population Estimates Released Today, Texas Counties Take Four of the Top Ten Spots in Numeric Growth

From the U.S. Census:

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.”

Among counties with a population of 20,000 or more, Williams County, N.D., was the fastest-growing county by percentage, increasing by 5.9 percent between 2017 and 2018 (from 33,395 to 35,350). The rapid growth Williams County, N.D., experienced was due mainly to net domestic migration (1,471) in 2018. The county also grew between 2017 and 2018 by natural increase (427) and international migration (52).

Of the other nine fastest-growing counties, all experienced positive domestic migration. All but Brunswick, N.C., and Hood, Texas, experienced growth through natural increase (having more births than deaths), and only Brunswick, N.C., had negative net international migration.

The statistics released today provide population estimates, rankings and components of change for the nation’s 390 metropolitan statistical areas, 555 micropolitan statistical areas, and 3,142 counties, as well as population estimates and rankings for Puerto Rico’s 78 municipios.

Additional Highlights

Counties

Growth and decline:

  • Out of 3,142 counties, 1,739 (55.3 percent) gained population between 2017 and 2018. Twelve counties (0.4 percent) experienced no change in population during this time, while the remaining 1,391 (44.3 percent) lost population.
  • Between 2010 and 2018, 1,481 (47.1 percent) counties gained population and 1,661 (52.9 percent) lost population.

  • Out of 3,142 counties, 1,757 (55.9 percent) counties experienced natural increase in 2018. This is down from 1,858 (59.1 percent) in 2017.

Total net migration:

  • Out of 3,142 counties, 1,640 (52.2 percent) counties showed positive total net migration in 2018, meaning more people moved into the county than moved out. This is roughly equivalent to the number of counties with positive net migration in 2017 (1,641 or 52.2 percent).

Percent Population Change by Metro/Micro Area: 2017-2018

Metropolitan Areas

Growth:

  • Two of the 10 fastest-growing metro areas in 2018 are in Texas: Midland, Texas (first), with a growth of 4.3 percent (7,383) and Odessa, Texas (fifth), with a growth of 3.2 percent (4,951). Positive domestic migration contributed to the growth in both areas. Florida and Utah also each contains two of the fastest-growing metro areas in 2018.

(-1.5 percent); Danville, Ill. (-1.2 percent); and Watertown-Fort Drum, N.Y. (-1.2 percent). The population decreases were primarily due to negative net domestic migration.
