Explore how IPUMS created this variable
Most IPUMS data transformations are performed using variable harmonization tables that specify how each value in the source data is recoded. Some variables also require programming logic in addition to the harmonization table. The harmonization documents for this variable are:
- Harmonization table
- Supplemental programming
- Instructions for interpreting harmonization documents

Where boundaries changed over time, units were harmonized to create units with boundaries that remain stable over time.
- The state of Tocantins was formed out of Goias in 1989.
- Mato Grosso do Sul split from Mato Grosso in 1979.
- The state of Guanabara was merged with the state of Rio de Janeiro in 1975.
- The municipality of Serra dos Aimorés received its own code in 1960, when its status was in litigation between two states. It subsequently became part of Minas Gerais by 1970.
- The 1970 sample is missing the island of Fernando de Noronha. The island was under military authority until 1981, and has been administered by the state of Pernambuco. Due to confidentiality issues, it was merged with Pernambuco in the 1960 and 1980 sample.
Missing states: The 1960 sample is missing 11 states, including the entire North region. These states are:
- Rondônia
- Acre
- Amazonas
- Roraima
- Pará
