The Census Bureau's web site has an enormous amount of information. If you need data from the 1990 Census, select the Access Tools option from their home page and then select 1990 Census Lookup . After selecting from STF1 or STF3 you will then be given a very long list of subjects. This is where you can select the geographic area and the data you need . Another great source for census information is American FactFinder .
