Modified Race Data

Modified Race Data

The race categories from each Census are reconciled with those race categories that appear in the data from administrative records, which are used to produce population estimates and projections. The types of modifications to the census data have been specifically developed each decade. This webpage includes documentation and links to data files for the Modified Race data from 1990 to 2020.

2020 Modified Race Data

The 2020 Modified Age & Race Census (MARC) files provide data from the 2020 Census in race categories that are consistent with the race categories used by the Population Estimates Program (PEP). Additionally, the age values for a subset of observations on the MARC files have been adjusted to produce more accurate age distributions.
