This is a follow-up to a couple questions regarding federal workers. In the IPUMS ACS sample (and CPS sample) there are MANY more federal workers than reported in ACS-IPUMS (empstatd== 10, classwkrd == 25) than .
Part of the reason is that “federal workers” in the ACS (and CPS) includes “employees of foreign governments, the United Nations, and other international organizations.” But this cannot account for the difference between the 3.6 million (CPS) and 2.6 million (OPM).
Any other suggestions on why these numbers could differ so dramatically?
Thank you very much,
