For the 2018 ASEC sample, all values of EMCONTRB are either 9999 (niu), missing, or zero. Is this a mistake or did they discontinue this item in CPS? Thanks!
Thanks to your inquiry, we found (and will correct) an error in the data source for EMCONTRB in IPUMS CPS for 2018. We anticipate that the corrected values will be available in the next month or two. Please email firstname.lastname@example.org so we can follow up about sending you a mug as a token of our appreciation for helping us improve IPUMS data.
Thank you, thank you! Earning and IPUMS mug has been a life goal! Huzzah!
