Interviewer instructions
Question G - State or foreign country of birth
When taking the respondent's declaration, the enumerator will consult the list of codes found on the left-hand side of the questionnaire; for native-born Brazilians, the enumerator will record the digits corresponding to the State declared, and for naturalized Brazilians and foreigners the code of one of the foreign countries specified on the list. The enumerator will write the name of the country in full only when no corresponding code is listed.
Code 28 (Serra dos Aimorés) should be recorded for persons born in this area in litigation between the states of Minas Gerais and Espírito Santo.
When the declaration is the Federal District, the enumerator will ask the respondent if he or she is referring to the present Federal District (Brasilia) or to the former Federal District (the present State of Guanabara) and will enter the respective code.

It should be noted that the term Rio de Janeiro is frequently declared. In this case, the enumerator should ascertain whether the respondent is referring to the state of Rio de Janeiro (Code 9) or the City of Rio de Janeiro (in the state of Guanabara - Code 12) and record as such.
