Within the United States, both natural population growth and the number of people moving are on the decline in recent years, according to the U.S. Census Bureau. But that doesn’t mean all the country’s towns and cities are experiencing population slowdowns. The city with the largest absolute population growth between 2010 and 2020 is Phoenix.

A variety of factors lead to population growth in cities and towns across the U.S. In places where the number of residents is growing, birth rates may be higher, death rates may be down, or people may be arriving for better job opportunities or a lower cost of living — or a combination of natural growth and migration may be occurring.

• Among cities with a population of at least 100,000 in 2020, Frisco, Texas, had by far the most explosive growth, with a 79.5% total increase since 2010 — 18% higher than the next fastest-growing city.

• Texas is home to 9 of the 15 fastest-growing cities in the U.S. by percentage population growth between 2010 and 2020. Seven are suburbs of Dallas, Houston or Austin.

• All 15 of the fastest-growing cities in the U.S. by percentage population increase are in the Southern or Western U.S.

• Five of the 10 fastest-growing cities in the U.S. by raw population are in Texas: In order from highest to lowest population increases, they are San Antonio, Houston, Austin, Fort Worth and Dallas.
