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.
1990 Modified Race Data
The 1990 Modified Age/Race, Sex, and Hispanic Origin (MARS) files provide data from the 1990 census that has been "modified" to assign each of the persons in the "other race" category to a specific race. This was done to make the census data consistent with the four race categories (within Hispanic or Not Hispanic) used in other census surveys White; Black; Asian and Pacific Islander; and American Indian, Eskimo, and Aleut.
