When calculating the homeownership rate on the household level using household weights, I find very high homeownership rates pre 1985 (for example 68% in 1980) which are not in line with Census homeownership rate estimates (https://fred.stlouisfed.org/series/RH…). Do you have an idea, where this difference is coming from?

Homeownership rate calculated as

SUM[HWTSUPP(OWNERSHP == 10, YEAR == y, RELATE == 101)]/SUM[HWTSUPP(YEAR == y, RELATE == 101)]
