Am I correct that there is no state variable in the NHIS dataset accessible via IPUMS? I was surprised not to see one but I wanted to double-check. I was trying to get the number of adult citizens enrolled in various programs by state, but it looks like I’ll have to use ASEC for this. Let me know if there are other data sets that come to mind that I should look into. Thank you!
Yes, that’s correct. State identifiers are only available in the restricted-use NHIS.
Just want to add that the restricted NHIS data can be accessed through an FSRDC: https://www.cdc.gov/rdc/b1datatype/Dt1225.htm
Also you may want to use data from the Survey of Income and Program Participation (SIPP), depending on your research question. The SIPP microdata has state-level identifiers.
