Shapefiles of places in IA in 2020

Description

The shapefiles are based on places in Iowa in 2020. The names of places and its population numbers are based on the decennial census counts for 2020, 2010, and 2000. Note that the US Census Bureau used differential privacy estimates for the 2020 Census, which might impact the exact numbers below county levels. In particular, for small areas, these estimates might differ from the actual population numbers.
