Iowa Population 25 Years and Over by Sex, Race and Educational Attainment (ACS 5-Year Estimate)

Published by Data Hub Administration | State of Iowa | Catalog Last Checked: June 09, 2026 at 06:19 PM | Dataset Last Updated: February 05, 2026 at 11:02 PM
This dataset provides population estimates for individuals 25 years and over by sex, race and educational attainment for State of Iowa, individual Iowa counties, incorporated places (i.e., cities) and census tracts within Iowa. Population estimates are used to track demographic changes, inform resource allocation, and plan for future needs. Data is from the U.S. Census Bureau, American Community Survey, Five Year Estimates, Tables C15002A, C15002B, C15002C, C15002D, C15002E, C15002F, and C15002G. The five year data are collected over a period of 60 months for all geographic areas. Estimates are more reliable for smaller areas (under 20,000 population). Values should not be aggregated across multiple variables, geographies, and years. Also, comparisons should not be made between overlapping data collection periods (e.g. 2012-2016 and 2013-2017).
