Is there a CPS to IPUMS CPS crosswalk? I am looking for the PEMLR variable from CPS and don't see an equivalent.

I see from a previous question that some CPS questions may not be available on IPUMS. Perhaps that is the case with PEMLR?

Unfortunately, there is not a crosswalk between the CPS and IPUMS-CPS variables. In your case, the variable EMPSTAT on IPUMS-CPS represents the data collected for the CPS variable PEMLR.

I hope this helps!
