2020 Census Data for Iowa Released
Aug 12, 2021
The State Data Center has received Iowa’s data for the 2020 Census from the U.S. Census Bureau. The 2020 Census data is available now on the State Data Center website at the link below.
The statistics provide the first look at populations for small areas and include information on Hispanic origin, race, age 18 and over, housing occupancy and group quarters. They represent where people were living as of April 1, 2020, and are available for Iowa communities down to the block level.
Iowa 2020 Census Quick Facts:
- Iowa’s total population is 3,207,031.
- The largest county is Polk with 492,401 population.
- Adams comes in as the smallest county with 3,704 population.
- The largest incorporated municipality in the state is Des Moines with 214,133 residents; while Le Roy, Iowa (Decatur County) claims the smallest, with a population of 11.
Overall, 99.9 percent of Iowa’s households were enumerated for the 24th decennial census, with 71.5 percent of households self-responding and 28.4 percent requiring follow-up from Census workers to be counted.
The original Census timeline was delayed months due to the pandemic, and the Iowa Legislature will now use the 2020 Census data in the upcoming redistricting process. The population counts will also determine how hundreds of billions of dollars in federal funding is allocated to communities across the country.
