Thank you for this reply! The consPUMA variable is very interesting. I don’t necessarily need it for my current study, since am not following a single PUMA over time. At the moment, I only need to compare a set of yearly ACS variables with a set of yearly county-level characterisics (collected to the PUMA level of geography). However, I’ll keep the consPUMA in mind for future needs!
Your reply has really helped me interpret the language in the technical documents that I’ve been reading. However, I want to be certain that we are on the same page. If you will indulge my reiteration of your instructions:
I am using ACS yearly data (1% sample) from 2000-2016 and need to find a county crosswalk.
I should use the FIPS county crosswalk for the 5% sample from 2005-2011 which are the same as the FIPS county codes for the 1% sample 2000-2011.
I should then rely on the crosswalk that allows me to compare 2000-2011 PUMAs to PUMAs from 2012-present to move from the 5% 2000 PUMAs to the counties in the 2012 1% PUMAs.
These two steps will allow me to observe which counties exist within each PUMA for the yearly/1% ACS data from 2000-present. Correct?
Thank you so much!!
