IPCA Monthly Inflation Rate (Brazil, Percent Change)

ibgesidra/ipca-monthly-variation

The month-on-month percent change of Brazil's IPCA consumer price index (monthly inflation, negative for a fall), for the most recent 1 to 12 months. Returned as IBGE's SIDRA rows: the first row labels the fields in Portuguese, the rest are one row per month, oldest first, with the value as a string in `V` and the month in `D3C` (YYYYMM) and `D3N`. Brazil-wide only. IBGE data, passed through unmodified and served by Eden Engine; not an official IBGE product.
