The CLASSWKR variable in ASEC breaks self-employment into non-incorporated and incorporated beginning in 1988 (codes 13 and 14). However, there is only one category (self-employed code 10) before 1988. Does this broad category include both incorporated and non-incorporated self-employed individuals? In addition, the CLASSWKLY variable (class of worker last year) in ASEC breaks self-employment into incorporated and non-incorporated all the way back to 1976. Would it be possible to obtain these breakdowns for CLASSWKR beginning in 1976?

Yes, in years prior to 1988 all types of self-employed people are combined into the one category ==10 “self-employed”. IPUMS CPS is only able to provide data as collected and provided by the US Census Bureau. In years prior to 1988 the detail available in [CLASSWLY](https://cps.ipums.org/cps-action/variables/CLASSWLY#codes_section) is unfortunately not available in [CLASSWKR](https://cps.ipums.org/cps-action/variables/CLASSWKR#codes_section).
