People of Iowa
This report highlights information about Iowa's population and it's characteristics. The information presented in this report is based on estimates provided by the U.S. Department of Commerce, Census Bureau as part of the American Community Survey, Five Year Estimates.
The American Community Survey (ACS) is an ongoing survey that provides vital information about our nation and its people. The five year estimates have a larger sample size and are therefore usually more precise, which are important when looking at small populations and population subgroups.
Population and median age estimates reported are from the most current five year data collection period. Change and % change are comparisons of the estimate from most current five year data collection period to the estimate from the previous non-overlapping data collection period. Change is the difference between the two estimates: current estimate - previous estimate. % Change divides that difference by the previous estimate.
