U. S. census data is available in print, microfiche, CD-ROM, and online, depending on the date. One way to begin searching for census data is to use reference works such as the ones listed below
Vassar has many census documents in print from the first census in 1790 through the 22nd census in 2000. Search the online catalog using the subject heading: United States Census 1st 1790 [substitute number and date of the appropriate census]
Early census materials are in LC classification and shelved in the main collection. Example:
Subject heading: United States Census 17th 1950
Later census materials are in the Superintendent of Documents Classification. Print volumes are shelved in the U.S. Government Documents collection. Census materials on CD ROM are also in the U.S. Government Documents area, except for CensusCD, which is on a workstation in the Reference room. Example:
Subject heading: United States Census 19th 1970
Subject heading: United States Census 20th 1980
Much of the 1980 census is on microfiche in the Microtext Room. The Census of Population and Housing is also in print in the documents collection.
The 1980 census is filed under "Census" in the non-document microfiche collection.
