How Current are the Data?

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

Currently, most data points are from 2017 datasets – specifically the 2017 American Community Survey (ACS) 5 year dataset. 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 Radius Reports and this site with the most current data throughout the year.
