Source: INE — VMAB. Each full year shows the median of that year's monthly values. The "year to date" row compares the months already published this year with the same months of the previous year, so an incomplete year is never compared with a full one. The latest-month row compares only that month with the same month a year earlier and shows the most recent pace. "Acima/below the region" compara a variação do município com a da região no mesmo período; diferenças de até 1 ponto percentual contam como "em linha".
