I am merging data from the 1980 ACS with 2005 ACS by conspuma.

I would like to confirm that this variable is comparable between both years. I mean that it is possible to merge both data set by that variable.

Thank you

Yes, CONSPUMA is fully comparable across years and identifies the most-detailed geographic areas that remained consistent from 1980-2011. You can find the exact components of each of the 543 CONSPUMAs here.

Hope this helps.
