Normalized to 2020 Boundaries

As geographic boundaries change over time, our normalized data product line adjusts for these changes to allow for apple-to-apple comparisons.  We have normalized census data originally set in boundaries from 1970, 1980, 1990, 2000 and 2010 to the 2020 boundaries.

We offer the full decennial census normalized to the 2020 boundaries for 1970, 1980, 1990, 2000 and then the American Community Survey (ACS) from 2009 (in 2000 boundaries) and the ACS from 2010-2019 (in the 2010 boundaries).
