The U.S. Census Bureau publishes demographic information including total population and demographic characteristics through its Population Estimates Program (PEP) and various survey programs. Select pieces of information for Arizona and its counties are presented in the “DEMOGRAPHICS” section below. Please note that, for methodological and other reasons, population estimates released by OEO, PEP, and Census Bureau survey programs are not identical.
Population estimates are published once a year near the end of the calendar year for the state, counties, and incorporated places.
Population projections are published for the state and counties in years ending with 2, 5, and 8. Population projections for sub-county areas are released in the years immediately following the publication of state and county projections.
Population Estimates for Arizona released by the U.S. Census Bureau’s Population Estimates Program (PEP) and demographic characteristics from the American Community Survey (ACS).
The State Data Center program coordinates an Arizona network of U.S. Census Bureau data users, provides training and technical assistance to them, and provides a mechanism for feedback to the Census Bureau.
