The Census Bureau posts 1980, 1990, and 2000 data at http://www2.census.gov/. I found technical documentation for 1990 and 2000, but I was not able to find any documentation for 1980 data. Thus, I have not been able to incorporate the 1980 data yet. Does anyone know where I could find technical documentation for the 1980 data?

The data we are specifically looking for is population and housing information at the block level for 1990. But we would also like to find data from 1980 if possible. We are trying to look at some of the trends in our area that have changed over time. Part of the study area for one of the projects is in a rural area and data at block group and track levels are very broad and difficult to determine trends. If anyone has any suggestions on where we could find this data it would be greatly appreciated. Thank you in advance for your help.
