In previous use of the 5% 1990 PUMS data, I was able to name the PUMA # and then go in and extract the raw data for that PUMA. I then used my own program to extract the data I wanted and analyze it. Can I still find raw data by specific PUMA? Is there still a mapping of the PUMA boundaries? If I can no longer do this, is it possible to do this by zip code? What other suggestions do you have?
