Can anyone point me to Stata or SAS code to import the [2018 CPS Unemployment Insurance Nonfilers supplement?
(Unemployment Insurance Nonfilers)
The Unemployment Insurance Nonfilers Supplement is not currently available through IPUMS CPS; I have not been able to find directly relevant sample code for it. NBER provides resources on how to import CPS data on their CPS-Basic page; see the link for Stata Code under Downloads. You may want to edit this code from NBER to import this supplement using the record layout available in documentation on the U.S. Census website.
