Hi folks, I’m trying to assess birthplace at the lowest geographical level of granularity. It seems that this is PUMAs, but I’d like someone with a bit more experience that this is, indeed, the case, and that some other survey tool run by the BLS/Census bureau/etc. doesn’t seem to have it available on any other lower granularity (e.g., block — for some reason I assumed census block may have this!).
So, is it actually the case that PUMAs, rather than ZTAs or other geographies, are the smallest parcels of land wherein we can get respondent birthplace data from?
