I am working on a project that differentiates between self-employment income and other income. I was told by the professor I work with that there is an “INCSE” (income for self-employed) variable, but I did not see this listed in any of the IPUMS variable lists. A google search also revealed that this variable exists, or at least one did, but I can’t find how to access it. I am specifically working with IPUMS USA 2000 5% sample.
Any help would be greatly appreciated. Thank you.
