Quarterly unemployment-rate intelligence from Brazil's official PNAD Contínua household survey via the keyless IBGE SIDRA API (table 6468, variable 4099): one row per calendar quarter per geography — Brazil, the 5 macro-regions and the 27 federative units — 2012-Q1 to the latest published quarter. Each row carries the published unemployment rate of persons 14+ in the reference week plus derived signals: quarter-over-quarter and year-over-year changes in percentage points (exact-spacing rule, never interpolated), structural change since the 2012-Q1 series start, the gap vs the national rate that quarter, and — for states — the within-quarter rank (1 = lowest rate) and labor-tightness quartile tier. Method: three SIDRA values calls (national/regional/state levels), fail-loud geo and quarter identity gates, deterministic 16-hex row hashes. Caveats: quarterly cadence with ~45-day publication lag; rates are survey estimates. Brazil's federal open-data framework (Lei 12.527/2011, Decreto 8.777/2016) fosters reuse including commercial use, with attribution to IBGE.
