Hi IPUMS staff,
I was doing some research using IPUMS-CPS and tried to aggregate industries to broad supersectors. For this I used IND1950 but it’s quite old structure and I need some recent basis say 1990. My question is can you create industrial codes with 1990 basis (IND1990)? For example, it is already available for Occupational Codes: OCC1950 and OCC1990. Thanks in advance.
