Consumer Price Index - Weekly

The Consumer Price Index - Weekly (CPI-W) measures the four-weekly variation in cost of living for families with incomes between 1 and 33 monthly minimum wages.

The indicator integrates the FGV IBRE system of consumer price indexes, which also includes CPI-3a, CPI-C1, CPI-DI, CPI-10, and CPI-M. Although prices are collected on a weekly basis, computation of variation rates considers the mean of the prices collected in the last four weeks up to the date of closing. The interval between the end of collection and its release is one day, which is a very quick turnaround, even by international standards.

Main Uses:
Quick and efficient detection of changes in the trajectory of prices of the products and services consumed by families.

Geographic Coverage:
Belo Horizonte, Brasília, Porto Alegre, Recife, Rio de Janeiro, São Paulo and Salvador.

Sector Coverage:
Food, Housing, Clothing, Health and Personal Care, Education, Reading and Recreation, Transport, and Miscellaneous Costs.

• From the 8th day of the base month to the 7th day of the reference month;
• From the 16th day of the base month to the 15th day of the reference month;
