1990 Census Block Data

Because I was curious, I wrote to Census, and got this reply:

Data from the 1990 census at the block level are available from 1990 Summary Tape File 1B (Tape or CD-ROM). You can contact your local State Data Center ( for assistance or purchase the tape or CD-ROM from our Customer Services Center. Their telephone number is 301-763-4636.

We are in the process of decommissioning the e-mail address . Please submit future request to our "Ask Questions" link at From the center of our web site, select the radio button "FAQs" and then go over to the right and click on the "GO" button. Select "Ask A Question." If you forget your password, please contact the Customer Services Center on 301-763-4636.

Again, we appreciate your interest in our data.

So, no, 1990 block data is NOT available from American Factfinder. 1990 block group data, yes; 2000 block data, yes.
