Population

Description: Estimates of the population, expressed as of July 1, are available annually. The Arizona Department of Commerce and the U.S. Census Bureau each produce estimates. Since the Census Bureau subdivides population change into its components of births, deaths, net domestic migration, and immigration, and since a long time series of estimates is available from the Census Bureau, its estimates are presented on the Economic and Demographic Indicators dashboard. The population estimates produced by the Census Bureau are used in formulas that determine the distribution of funding from many federal programs.

Population data are presented on the Economic and Demographic Indicators dashboard since 1969 for the United States, Arizona, and the 15 Arizona counties. State and national data are reported in December. County data are released in March.

Data Sources: U.S. Department of Commerce, Census Bureau. The latest data can be obtained at http://www.census.gov/popest/counties but the historical data are more easily accessed from the Regional Economic Information System, Bureau of Economic Analysis, U.S. Department of Commerce: http://www.bea.gov/regional/reis/default.cfm?catable=CA1-3&section=2.

Comments on the Quality of the Data: Other than the birth and death components, the change in population is estimated, benchmarked to the latest decennial census count. Estimates may be revised substantially after the decennial census count is available.
