Census 2020

Phoenix is now the fifth largest city in the country. Buckeye grew faster than any other city in the nation. Maricopa County added more residents than any other county in the country. Other regional highlights in the newly released data from the U.S. Census Bureau include:

  • Queen Creek has the highest population growth (126%) and housing growth (129%) in the state by percentage.
  • The minority population in Maricopa County grew at a rate almost twice as fast (30.8%) as the total population (15.8%), from 41.3% in 2010, to 46.7% in 2020.
  • The Ak-Chin Indian Community and Gila River Indian Community are among the communities statewide with the highest percentage of residents under 18 years old.
  • Maricopa County’s vacancy rate dropped from 13.9% in 2010 to 9.3% in 2020. Pinal County’s rate declined from 21.1% to 15.2% over the same period. In those two counties, Guadalupe (4.3%) and Youngtown (4.4%) had the lowest vacancy rates.
  • Phoenix remains the largest city in the state, followed by Tucson, Mesa and Chandler. Gilbert passed both Glendale and Scottsdale to become the fifth largest municipality in Arizona.

“This new Census information found what we in the Maricopa region already know – it’s a great place to live, work and play,” says Mesa Mayor John Giles, chair of the Maricopa Association of Governments (MAG). “Our advances in economic development, job growth, and the high quality of life are making this region one of the most attractive in the nation.”

MAG now has new tools to help local governments and the public access 2020 Census data in a meaningful way. You can find maps, tables and an interactive viewer on MAG’s website here. Information includes population and housing summaries; population by race and ethnicity; voting age population, and vacancy rates.

The data represent the first local level results from the 2020 Census. The results are used by states to redraw the boundaries of their congressional and state legislative districts, and by some cities to redraw council districts, for the next ten years.
