Retrieving PPI data from the PPI Web site.

PPI data can be obtained from the WWW address (www.bls.gov/ppi). On this page, under the tab labeled "Featured PPI databases" links provide the following methods of data retrieval:

* Top Picks is a form-based application for both Industry Data and Commodity Data that allows the user to quickly obtain PPI time series data by selecting the high-level aggregate and other commonly requested time series, including the All Commodities Index and the FD-ID indexes (for example, Final Demand). Within each list, any one--or all--of the time series shown can be selected. A user can modify the date range and output options after executing the query, using the reformat button above the data output table.

* One-Screen Data Search and Multi-Screen Data Search are form-based query applications for both Industry Data and Commodity Data designed for users unfamiliar with the PPI coding structure. These applications guide a user through the PPI classification by listing index titles and do not require knowledge of commodity or industry codes. Data retrieved are based on a query formulated by selecting data characteristics from lists provided. Two options are available to create customized tables, depending on a user's browser capability. The one-screen option is a JavaScript application that uses a single screen to guide a user through the available time series data. The second option is a multiple-screen, non-Java-based application. Both methods allow a user to browse the PPI coding structure and select multiple series. Users can modify the date range and output options after executing the query using the reformat button above the data output table.

* Series Report is a form-based application that allows users to input multiple, formatted PPI time series identifiers (commodity or industry codes) as inputs in extracting data according to a specified set of date ranges and output options. This application provides the most efficient path for users who are familiar with the format of PPI time series identifiers. There are five alphabetic prefixes used to create unique PPI time series identifiers: WP, WD, PC, PD, and ND. Each provides the user access to a different PPI database. Adding either a "u" (not seasonally adjusted) or an "s" (seasonally adjusted) to the end of these prefixes further specifies the type of data needed.

EXAMPLES

For commodity and FD-ID indexes, series identifiers combine a "wpu" prefix (not seasonally adjusted) or a

"wps" prefix (seasonally adjusted) with a commodity code.
Commodity code   Provides data for:

wps141101        Passenger cars, seasonally adjusted

wpu141101        Passenger cars, not seasonally adjusted

wpufd4           Final demand, not seasonally adjusted

wpsid63          Services for intermediate demand,
                 seasonally adjusted


For discontinued commodity indexes, series identifiers combine a "wdu" prefix (not seasonally adjusted) or a "wds" prefix (seasonally adjusted) with a commodity code.
Commodity code   Provides data for:

wds019           Other farm products, seasonally adjusted

wdu0635          Preparations, ethical (prescription),
                 not seasonally adjusted

wdusi138011      Stainless steel mill products,
                 not seasonally adjusted


Current price indexes grouped by industry according

to NAICS have series identifiers that begin with the prefix "pcu." After the prefix, there are 12 digits (the 6digit industry code is listed twice) followed by up to 7 alphanumeric characters identifying product detail. Dashes are used as placeholders for higher-level industry group codes.
Industry-product code,
current NAICS series     Provides data for:

pcu325-325-              Chemical manufacturing

pcu336110336110          Automobile and light duty
                         motor vehicle manufacturing

pcu621111621111411       Offices of physicians, one- and
                         two-physician practices and
                         single-specialty group
                         practices, general/family
                         practice


Discontinued industry-product codes based on SIC

combine a "pdu" prefix and "#" between the fourth and fifth characters of the product code. Series identifiers for the discontinued dataset use underscores as placeholders to complete a reference to an SIC industry group code of fewer than four digits. (All PPI industry-based indexes organized by SIC were discontinued with the introduction of NAICS in 2004.)
Industry-product code,
discontinued SIC series   Provides data for:

pdu28__#                  Chemicals and allied products

pdu331_#                  Blast furnaces, steel works,
                          and rolling and finishing mills

pdu3711#111               Passenger cars


Price indexes for discontinued series grouped by industry according to NAICS have identifiers that begin with the prefix "ndu." After the prefix, there are 12 numeric digits (the 6-digit industry code is listed twice), and up to 7 additional alphanumeric characters that identify product detail. Dashes are used as placeholders for higher-level group codes.
Industry-product code,
discontinued NAICS series   Provides data for

ndu212231212231             Lead and zinc ore mining
ndu2122312122312            Lead, zinc concentrates
ndu212231212231214          Lead concentrates


Text Files are best suited for users requiring access to either a large volume of time series data or other PPIrelated documentation, such as seasonal factor tables and relative importance tables. The text files can be accessed at http://download.bls.gov/ or directly from links on the "PPI Databases" page or the PPI homepage. Data and documentation available for download include the following:
