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. Aziz. ---

An IND1990 variable is being constructed for IPUMS-CPS, however there is currently no projected release date for this variable. In the mean time, you are welcome to construct your own version of IND1990 based on the IPUMS-CPS [IND](https://cps.ipums.org/cps-action/variables/IND#description_section) variable (paying special attention to the[Comparability section](https://cps.ipums.org/cps-action/variables/IND#comparability_section)) and a combination of the [IPUMS-USA](https://usa.ipums.org/usa/) variables [IND](https://usa.ipums.org/usa-action/variables/IND#description_section) and [IND1990](https://usa.ipums.org/usa-action/variables/IND1990#description_section) (which is the basis of the future IPUMS-CPS variable). I hope this helps.
