http://stats.bls.gov/ppihome.htm PRODUCER PRICE INDEX
The Producer Price Index (PPI) measures the average change in selling prices received by domestic producers for their output. The prices included in the PPI are from the first commercial transaction. The PPI collects price data from producers in the mining, manufacturing, agriculture, fisheries, forestry, and service sectors of the economy.
There are three primary systems of producer price indexes:
Over 3,200 commodity price indexes organized by type of product and end use. Over 500 industry price indexes, including price indexes for approximately 9,750 specific industry products and product categories. Several major aggregate price indexes organized by both commodity-based and industry-based stage of process.
Other data include: Annual average indexes for all groupings and items. Regional indexes for electric power, bituminous coal, and a few others. Special commodity grouping indexes, for example: Fabricated metal products and Construction materials. Seasonally adjusted stage of processing indexes.
Price change for the entire output of the domestic goods-producing sectors: Agriculture, forestry, fisheries, mining, scrap, and manufacturing industries.
Price change for a growing portion of the output of the domestic services sector, e.g., transportation, help supply services, and health services.
Source of data
The PPI sample includes approximately 34,000 establishments that provide close to 119,000 price quotations. Participating establishments report price data primarily through the mail. Goods and services included in the PPI are weighted by value-of-shipments data based on the 1987 economic censuses.
Industries and products are systematically resampled as needed.
For most items, establishments report their selling price as of Tuesday of the week containing the 13th of each month.
These tables are based on figures supplied by the United States Census Bureau, U.S. Department of Commerce and are subject to revision by the Census Bureau.
