In the CPS, are the values for INCDISAB and INCSSI mutually exclusive?

From what I understand, the INCSS and INCDISAB are mutaully exclussive. But I am wondering if INCSSI and INCDISAB are as well.

Thank you!

Yes, INCSSI and INCDISAB are mutually exclusive from each other. This can be verified by looking at the INCTOT comparability tab. INCTOT reports the total amount of income for each individual, and both INCSSI and INCDISAB are included in the aggregation.
