The IGP series are calculated by Foundation Getulio Vargas FGV/IBRE and have three different versions: IGP-M, IGP-DI and IGP-10. The main difference between these indicators is the period of data collection. IGP-M covers from the 21st day of previous month to the 20th day of current month, IGP-DI goes from the 1st day to last days of current month and IGP-10 range is from the 11th day of previous month to 10th day of current month. Each of the IGP inflation series is composed by three components, IPA (Wholesale Prices) with 60% weight, IPC (Consumer Prices) with 30% weight and INCC (Construction Cost) with 10% weight. The IGP series (Indice Gerais de Precos,), produced by Foundation Getulio Vargas (FGV) in Rio de Janeiro, measures inflation by taking a weighted average of wholesale prices (60%), consumer prices (30%) and construction costs (10%). This series includes IGP-M, IGP-DI and IGP-10. The main difference in these is the period of data collection. IGP-M goes from the 21st day of the previous month to the 20th day of the current month, IGP-DI goes from the 1st to last day of the previous month, and IGP-10 begins on the 11th day of the previous month and ends on the 10th day of the current month. For IGP-M, two previews are released in addition to the final figure. The first preview covers the first 10 days of data collection and the second preview covers the first 20 days. Wholesale prices (IPA) are broken down by stages: raw materials, intermediate and final goods. Consumer prices (IPC) are comprised of the following categories: food, housing, clothing, health/personal expenses, education/recreation, transportation and other. Construction costs (INCC) are broken down by two categories: materials/services and labor. FGV also includes in their release the goods/services that contributed the most to inflation for the given collection period.
