Where I can download the 1990 SF1 and SF3 tables? I've been on the Census web site at:
http://factfinder.census.gov/servlet/DatasetMainPageServlet?_program=DEC&_tabId=DEC2&_submenuId=datasets_1&_lang=en&_ts=211801213781

but it seems I can only download data one tract at a time. I would like to have the SF1 and SF3 tables for our whole county (Dane County, WI) by block and block group. Any help is appreciated, thanks.
