The Twenty-first United States Census, conducted by the Census Bureau, determined the resident population of the United States to be 248,709,873, an increase of 9.8 percent over the 226,545,805 persons enumerated during the 1980 Census.
Approximately 16 percent of households received a "long form" of the 1990 census, which contained over 100 questions. Full documentation on the 1990 census, including census forms and a procedural history, is available from the Integrated Public Use Microdata Series.
It was the first census to designate "Native Hawaiian and Other Pacific Islander" as a racial group separate from Asians.
Microdata from the 1990 census is freely available through the Integrated Public Use Microdata Series. Aggregate data for small areas, together with electronic boundary files, can be downloaded from the National Historical Geographic Information System.
