I’m compaing IPUMS-CPS WKSTAT with the BLS/CPS PRWKSTAT. I take it the two are the same, except the codes are different. However, I notice that who is classified as full-time according to IPUMS (code numbers are between 11 and 15) is different from the BLS/Census classification (codes 2 through 5).
According to the BLS/Census classification, full time is:
FT Hours (35+), ususally FT + PT for eco reasons, usually FT + PT for non-eco reasons, usually FT + Not at work,usually FT.
According to IPUMS, Full-time is classified as:
FT Hours (35+), ususally FT + PT for non-eco reasons, usually FT + Not at work,usually FT + FT hours, usually PT for eco reasons + FT hours, usually PT for non-eco reasons
According to IPUMS, people working PT non Eco but usually FT can be classified as FT (see code 12) and people working FT but usually PT are also FT (codes 14 and 15). But if the individual is PT Econ,usually FT (code 21), they are not classified as FT.
According to the BLS/Census, only those who are PT but usually FT are classified as FT but not th other way around.
Why is the IPUMS classification for full-time different from the BLS/Census’s especially given that WKSTAT is just a recode of PRWKSTAT?
