IND What are the industry labels when combining 4 digits to 2 digits?

2

If you are referring to the Detailed or Major Industry recodes, the Codebooks on the IPUMS-CPS website include these recodes, generally under Appendix A. Note that these recodes do not represent a simple 2-digit truncation of the 4-digit codes from the IND variable.

I hope this helps.
