How Current are the Data?

The Iowa demographics on this site are the most current data available from the US Census Bureau.

Currently, most data points are from 2022 and 2023 datasets – specifically the 2023 Population Estimates Program and 2022 American Community Survey. We use the Census' ACS 5-year dataset for 3 reasons.

  1. It's updated every year.
  2. It typically has the smallest margins of error of the Census' ACS datasets.
  3. It allows for apples to apples comparisons of large geographies to small geographies (i.e. state data to city data).

We're constantly updating the demographic reports and this site with the most current data throughout the year.
