Population projections for Arizona and its sub-geographies on this page are produced by the Arizona Office of Economic Opportunity (OEO). Projected growth rates for the United States are from the 2017 edition of population projections produced by the U.S. Census Bureau.
Please Note: OEO Population projections are based on the 2010 Census and were created without incorporation or consideration of the 2020 Census results. As a result, the population projections for 2020 published here are not consistent with the 2020 Census results that were recently released. Our next population projections series to be released at the end of 2022 will be based on the 2020 Census.
