Note: For 1910, Social Explorer and other online databases of older census information display data only down to the county level.
PDFS of the print volumes posted by the US Census Bureau:
The Census Bureau Census of Population and Housing page includes pdfs for many of the census years along with information about what is included.
Please note: In IE (Internet Explorer) you can use the "Title Page" as a Table-of-Contents with links to the section of the census you need (this is easier than downloading huge zip files).
Over the years, the census becomes increasingly complex and is published in various parts (i.e. Census of Manufactures, Census of Agriculture, etc.)
Print volumes in the Olin Library Stacks:
Please note: Searching the library catalog to find call numbers for the decennial census can be tricky because there are so many different census products and reports. This table provides links to the online pdfs, when available, and a local call number for the Census of Population.
Beginning around 1930, if you are looking for housing, manufactures, agriculture, etc., use a subject heading search: United States Census, (census number), (census year). Example: United States Census, 15th, 1930. [subject heading]. to browse through the census products available for that year.
You might also combine the subject phrase with a keyword in the Guided Keyword search, however, you will need to know what terms were used (for example, manufactures rather than manufacturing, etc.). The U.S. Bureau of the Census, Catalog of Publications (Olin Reference, Z 7554.U5 U58) can sometimes be helpful for identifying these.
