Hello, I work on the 1980 Brazilian Census.
The household weight variable (WTHH) has some values equal to zero. Is this normal?
I find this weird. If I understand well, the households concerned are only useful for some person-level analysis: their household members represent part of the Brazilian population but the households themselves are not representative of anything.
Thank you for your help. The whole job you are doing guys at IPUMS is unbelievable!
