EARNWEEK2 and N.I.U. codes after 1994

CPS

I noticed that starting in 1994, there are respondents who are coded as ELIGORG == 1 but are coded as N.I.U. for EARNWEEK2 (9999.99). I was wondering if this was an error, as the one found for those coded N.I.U. for EARNWEEK (999.99) here in the March 2025 revision:https://cps.ipums.org/cps-action/revisions

Thanks for your inquiry. I had a look at this today but haven’t found the answer yet. I will continue my investigation at the beginning of next week.
