The PPI is a family of indexes covering the output of all industries in the goods-producing sector of the U.S. economy and most of the service sector, as well as construction, natural gas and electric utilities, and goods competitive with those made in producing sectors (such as scrap materials).
All PPIs are organized into an Industry Classification System and a Commodity Classification System, each of which draws from the same survey of price samples. In other words, both contain data for all goods and services that PPI covers. Choose which data is right for you from the lists on the following tabs, by first understanding their differences.
Organizes prices by the North American Industry Classification System (NAICS) and measures the average change in prices received by establishments in the industry for individual products and services, as well as total output sold outside of the industry (that is, its net output). Every industry has primary product indexes to show changes in prices received for products made primarily, though not necessarily exclusively, by that industry. (Primary products are essentially the products for which the industry is titled.) In addition, most industries have secondary product indexes that show changes in prices received by establishments classified in the industry for products chiefly made in some other industry. Finally, some industries have miscellaneous receipts indexes to show price changes in other sources of revenue that are not derived from sales of their products—for example, resale of purchased materials or revenues from parking lots owned.
These indexes are derived from industry-based, primary product PPIs, and the weights used to develop this model are based on 2002 benchmark input/output relationship data from the Bureau of Economic Analysis (BEA). More information...
Organizes prices received by sampled establishments for individual and groupings of products or services by similarity, regardless of the producing establishment's industry classification. This system uses the original PPI (formerly "Wholesale Price Index") publication structure and does not match any other standard coding structure, such as the NAICS. The contents of a commodity index may be determined by its title and its place in the PPI commodity hierarchy (see PPI Relative Importance Tables).

These indexes regroup commodity data according to the class of buyer and the amount of physical processing or assembling the products have undergone. Components and weights for these indexes are available in the PPI Relative Importance Tables. The three stages of processing include finished goods; intermediate materials, supplies, and components; and crude materials for further processing. The PPIs for finished goods and for finished goods less food and energy (popularly referred to as "finished core") are the indexes most referred to in the media. More information...
These indexes regroup commodity data according to durability. Durable goods are considered to have a life expectancy of three years or more, while nondurables are either consumed in a single usage or have a life expectancy less than three years.
These indexes regroup commodity data into special aggregations. Components are listed in the monthly PPI Detailed Report following Table 8. Weights of the components are those used for the PPI for all commodities (see PPI Relative Importance Tables: Commodities, all levels).
This Experimental Aggregation system takes advantage of PPIs expansion of coverage over the last twenty years to include portions of the services and construction sectors by combining indexes for those sectors with the currently highlighted goods sector indexes. More information, including components and weights are available on the Experimental Aggregation Webpage.
For seasonally adjusted data, replace "WPU" with "WPS" in the series id code.
