About this table

Notes

• id is INEP's NU_SEQUENCIAL from the RESULTADOS file, a surrogate that is unique within a year but not across years: INEP appears to reuse the same shuffle, so the same number is a different person in 2024 and 2025. Do not use id to follow anyone between years, or to link to INEP's PARTICIPANTES file, which INEP ships with no key to RESULTADOS. (irw#2812)

These notes describe the source data, which the IRW reproduces as released. All notes are listed on the Data Notes page.
