I am looking for summary tables that show the number of native-born non-Hispanic White residents for each census tract in the United States. I found such data for years 2000 and after, but I cannot find the data for years 1970, 1980, or 1990. Do you know where I can find the information? Thanks for your help in advance!
This information is not available prior to 2000 in IPUMS USA or IPUMS NHGIS. You could take a look at the published Census Volumes for those years. Another option depending on your data needs is to request access to the non-public Census data through an FSRDC.
Thanks for your help!
