Does anyone have any clarity on the DWWKSUN code list? I am assuming that 999 means the person never regained employment? It looks like after 1996 these are all unemployed/NILF people, but that’s not currently documented on the website as far as I can tell.
The nonresponse codes for DWWKSUN are as follows:
996 Refused
997 Don’t Know
998 No Response
999 NIU
The IPUMS CPS team will add these codes in a future documentation update. Thank you for pointing out that these were missing from the codes page.
