The State Demographer's Office develops the official population estimates and projections for the State of Arizona. It collects and reviews data (sometimes called symptomatic indicators of population change) and conducts research to improve the accuracy of the demographic models used in estimates and projections. The State Demographer's Office works collaboratively with the U.S. Bureau of the Census to facilitate the use of demographic information in Arizona.

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.
These Policies pertain to the Population Estimates Challenge Program and the Inclusion of Sub-County Population Estimates and Projections Made by Councils of Governments.
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.
The State Demographer's Office processes and analyzes Census data and publishes them in formats that best meet the needs of data users.
