The Consumer Price Index (CPI) measures the variation in prices of a fixed group of goods and services comprising the regular expenses of families with incomes between 1 and 33 monthly minimum wages.
The structure of family consumption used in CPI calculation is based on IBGE’s Family Budget Survey (POF) and updated with each new edition of the survey. The weighting structures thus express, in percentages, the monetary importance of the goods and services comprising the CPI sample.
The goods and services that make up the sample are classified in eight groups or expense categories, 25 subgroups, 85 items, and 338 subitems.
