Coverage

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).

Classification

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.

About PPI Industry Data

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.

Example:
311--- Food manufacturing
3118--  Bakeries and tortilla manufacturing
31181-   Bread and bakery product manufacturing
311812    Commercial bakeries
311812-P     Primary Products
311812-1     Bread
311812-A     Pies
311812-S     Secondary products
311812-M     Miscellaneous receipts

Classification Systems within PPI Industry Data

Industry Data for Material and Supply Inputs to Construction Industries

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...

About PPI Commodity Data

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). For further clarification, contact PPI at ppi-info@bls.gov or (202) 691-7705.

Example:
01  Farm Products
011  Fruits and melons, fresh/dry vegetables and nuts
0111  Fresh fruits and melons
011101  Citrus fruits
01110101  Grapefruits

Classification Systems within PPI Commodity Data

Commodity-based PPIs by Stage-of-Processing (SOP)

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...

Commodity-based PPIs by Durability of Product

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.

Commodity-based PPI Special Groupings

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).

Commodity-based PPI Experimental Aggregation System

This Experimental Aggregation system takes advantage of PPI’s 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.
