I was looking at employment by education, and noticed some really odd estimates in the CPS ASEC. From 2002 to 2003, the number of workers aged 25 and older (age>=25) with a high school diploma, but no bachelor’s degree (educ>=73 & educ <111) working as retail sales workers (occ2010=4760) doubled. Increasing from 720K to 1.5 million.
The 1.5 million number is what I would expect, and corresponds with what you see in the decennial Census for 2000.
Overall, employment among retail sales workers is about half of what I’d expect across all education groups in years 2000 to 2002. I haven’t looked at years prior to 2000, so not sure where the issue starts.
I also plan to contact the Census Bureau about this, but am curious if someone at IPUMS, or other researchers may have any insights?
UPDATE: This doesn’t seem to be an issue with occ2010, but with the occ code. The 1992 to 2002 scheme had 6 different occ codes classified retail sales workers by sector, and then starting in 2003, the codes were collapsed to a single “retail sales workers” category.
