----------------------------Original message---------------------------- Folks -- Has anyone found a "good" source for digital data for the 1970 and/or 1980 Census. Our Wessex data for 1990 is proving to be a gold mine, and so much easier to use than the federal data, and we have the 1980 boundary files from American dbf but we now have a project going where the 1970 and 1980 data would be valuable. I'm aware of some datasets from the Urban Land Institute, which are in SAS, but is there anything else that people may be aware of?? Also, county level data is not of much use to us. We would like it at least to the town level and tract data would be very good. Any advice will be greatly appreciated. ***************************************************************** David A.
