CensusCD 1980. It took until 1999, but finally 1980 Census data is in a format that anyone can use. Time series analysis on areas as small as a Census Tract, can now be done with over 1,500 variables. Mapping software and boundaries for 1980 tracts, counties, states, places, and MCD, are included. http://www.geolytics.com/censuscd1980/censuscd1980.htm Natasha Vasilev GeoLytics
