Population estimates on this page are produced by the Arizona Office of Economic Opportunity (OEO). If you are looking for population estimates for Arizona that are released by the U.S. Census Bureau, please go to the DEMOGRAPHICS page or visit the U.S. Census Bureau website directly.
Please Note: OEO Population estimates for 2010 through 2020 are based on the 2010 Census and were created without incorporation or consideration of the 2020 Census results. As a result, the July 1, 2020 estimates published here are not consistent with the 2020 Census results that were recently released. Starting 2021, OEO population estimates will be based on the 2020 Census.
