I work on the Brazilian Censuses from 1980 to 2010. Can you tell me precisely the income sources comprised in the variable INCTOT and whether they are comparable across years, please? Also, is there any way I can access the whole set of INCTOT’s unharmonized (ie. source) variables? This is quite important for me because INCTOT is my main variable of interest.
I have looked at the IPUMS documentation but it is not very clear to me. For instance, it is written on the comparability page that in 2000 and 2010, INCTOT “includes labor income and income from sources such as retirement, pension, social programs and returns on financial investments.” To me, this implicitly means that INCTOT does not include pension income in 1980. Yet, when summing INCTOT’s source variables in 1980 (BR80A_GROSSINC BR80A_INCOTHER BR80A_INCPENS BR80A_INCRENT), which includes pensions, I never end up with a value higher than INCTOT (so pension income seems to be included in INCTOT in 1980 in fact).
Thank you very much for your help.
