I have downloaded data since 1950-2018 from IPUMS USA. As I browse my data, I see the variable UHRSWORK has some rows as top coded since 1980. From the articles I read and browsing IPUMS forum, I see it is INCWAGE that is top coded, not UHRSWORK. INCWAGE code shows (INCWAGE_CODE it is top coded since 1990.
Is there a correspondence I am missing? How can I replace the top-coded values in UHRSWORK?
