Producer Price Indexes -- April 2001
The Producer Price Index for Finished Goods rose 0.3 percent in April,
seasonally adjusted, the Bureau of Labor Statistics of the U.S. Department
of Labor reported today. This increase followed a 0.1-percent decline in
March and a 0.1-percent gain in February. The index for finished goods
other than foods and energy moved up 0.2 percent, compared with a 0.1percent increase in March. Prices received by producers of intermediate
goods fell 0.2 percent in April, the same rate of decrease as in the prior
month. The crude goods index turned up 0.9 percent, following a 1.7percent drop in March. (See table A.)

Prices for finished energy goods led the acceleration in the finished
goods index by edging up 0.1 percent in April, after dropping 2.6 percent
in March. Capital equipment prices also contributed to this acceleration,
although to a lesser extent, by advancing 0.3 percent in April, after
showing no change in the previous month. By contrast, price increases for
finished consumer foods slowed from a 1.1-percent rate of increase in March
to a 0.6-percent rate in April. The index for finished consumer goods
other than foods and energy increased 0.2 percent in April, after moving up
0.3 percent in the prior month.
Before seasonal adjustment, the Producer Price Index for Finished
Goods advanced 0.5 percent to stand at 141.7 (1982=100). From April 2000
to April 2001, finished goods prices gained 3.7 percent. Over the same
period, the index for finished energy goods increased 13.5 percent,
finished goods other than foods and energy advanced 1.6 percent, and
finished consumer foods rose 3.1 percent. Prices received by producers of
intermediate goods increased 2.0 percent for the 12 months ended April
2001, and the index for crude goods advanced 19.4 percent during the same
period.
Finished goods
Prices for finished energy goods turned up 0.1 percent in April, after
registering a 2.6-percent decline in March. The gasoline index advanced
7.0 percent, following a 0.5-percent rise in the prior month. Home heating
oil prices turned up, after declining in March.
The indexes for liquefied
petroleum gas and diesel fuel fell less than they did a month ago.
Conversely, the index for residential natural gas decreased 4.3 percent in
April, following a 4.0-percent drop a month earlier.

r=revised. Some of the figures shown above and elsewhere in this release may
differ from those previously reported because data for December 2000 have been
revised to reflect the availability of late reports and corrections by respondents.
Capital equipment prices advanced 0.3 percent in April, after showing
no change in March. The index for electronic computers turned up 1.5
percent, following a 5.9-percent drop in the previous month. Civilian
aircraft prices rose more than they did a month ago. The indexes for
tools, dies, jigs, fixtures, and industrial molds and for office and store
machines and equipment showed no change in April, after falling in the
prior month. Prices for pumps and compressors and for truck trailers
turned up, following March declines. By contrast, the index for passenger
cars increased 0.2 percent in April, after advancing 0.6 percent in March.
Prices for light motor trucks, commercial furniture, and heavy motor trucks

also rose less in April than they did in the prior month. The index for xray and electromedical equipment declined at a faster rate than it did in
the prior month.
The finished consumer foods index advanced 0.6 percent in April, after
posting a 1.1-percent gain in March. Pork prices rose 2.0 percent,
following a 7.8-percent increase in the prior month. The index for beef
and veal also rose less in April. Prices for fresh and dry vegetables,
bakery products, and for shortening and cooking oils turned down in April,
after rising in the prior month. By contrast, prices for eggs for fresh
use jumped 37.0 percent in April, following a 9.1-percent decline in the
previous month. The indexes for finfish and shellfish, processed turkeys,
and for processed fruits and vegetables also rose, after falling in March.
In April, the index for finished consumer goods other than foods and
energy edged up 0.2 percent, following a 0.3-percent gain in March. Prices
for prescription drugs, alcoholic beverages, newspaper circulation,
passenger cars, sanitary papers and health products, and pet food rose in
April. These increases outweighed falling prices for men's and boys'
apparel, book publishing, household appliances, household furniture, and
for lawn and garden equipment.
Intermediate Goods
The Producer Price Index for Intermediate Materials, Supplies, and
Components declined 0.2 percent in April, seasonally adjusted, the same
rate of decline as in March. Decreasing prices for intermediate energy
goods, nondurable manufacturing materials, durable manufacturing materials,
and intermediate foods and feeds outweighed increasing prices for
manufacturing components and construction materials. Excluding foods and
energy, the index for intermediate materials, supplies, and components
decreased 0.1 percent, after increasing 0.1 percent in the previous month.
(See table B.)
Prices for intermediate energy goods fell 1.5 percent in April,
following a 1.4-percent decline in March. Falling prices for jet fuels,
liquefied petroleum gas, commercial natural gas, commercial electric power,
diesel fuel, industrial electric power, and industrial natural gas more
than offset increasing prices for gasoline.
By dropping 2.3 percent, basic organic chemical prices led April's 0.4percent decline in the index for nondurable manufacturing materials.
Prices for nitrogenates, medicinal and botanical chemicals, and woodpulp
also moved down. Conversely, the basic inorganic chemicals index rose 2.4
percent in April. The indexes for plastic resins and materials, finished

fabrics, and leather also increased.
Prices for durable manufacturing materials declined 0.6 percent in
April, following a 0.2-percent decrease in March. The aluminum mill shapes
index dropped 0.9 percent, after increasing 0.1 percent in the previous
month. Prices for primary aluminum (except extrusion billet) and for
copper cathode and refined copper fell more than they did in March. The
indexes for cement, plywood, prepared paint, and gold turned down, after
showing gains in the prior month. On the other hand, prices for steel mill
products fell 0.6 percent in April, compared with a 0.9-percent decrease in
March. The index for copper and brass mill shapes also fell at a slower
pace in April than it did in March. Prices for metal foil and leaf turned
up, after falling last month. Flat glass price increases accelerated in
April.
The index for intermediate foods and feeds edged down 0.1 percent,
after posting a 0.5-percent gain in March. Price decreases for prepared
animal feeds, flour, and snack chips were offset by increasing prices for
fluid milk products; pork; frozen ground meat patties; and for natural,
processed, and imitation cheese.
For the second straight month, prices for components for manufacturing
increased 0.2 percent. Rising prices for aircraft engines and engine
parts, non-automotive metal stampings, plastic transportation parts, and
industrial rubber products outweighed falling prices for motor vehicle
parts, machine shop products, and closed die steel forgings.
As in March, the April index for materials and components for
construction increased 0.1 percent. Advancing prices for plastic
construction products, softwood lumber, millwork, wiring devices, asphalt
felts and coatings, and switchgear were offset by declining prices for
gypsum products, nonferrous wire and cable, plumbing fixtures and brass
fittings, plywood, and cement.
Crude goods
The Producer Price Index for Crude Materials for Further Processing
advanced 0.9 percent, seasonally adjusted, after registering a 1.7-percent
decline in March. Accounting for this upturn, prices for crude energy
materials increased in April, following a March decrease. By contrast, the
index for crude foodstuffs and feedstuffs fell, after rising in the prior
month, and basic industrial material prices fell more than they did in
March. (See table B.)
The index for crude energy materials rose 3.0 percent in April,

following a 4.9-percent drop
a 3.8-percent advance, after
month. Also contributing to
index increased 2.4 percent,
earlier. Coal prices gained
previous month.

in March. Natural gas prices led the way with
posting a 4.7-percent decline in the prior
this month's acceleration, the crude petroleum
compared with a 7.1-percent decrease a month
0.3 percent, after falling 0.4 percent in the

The index for crude foodstuffs and feedstuffs declined 0.5 percent in
April, following a 3.0-percent jump in March. Slaughter hog prices dropped
4.8 percent, after a 13.8-percent rise in the prior month. The indexes for
slaughter cattle, slaughter broilers and fryers, wheat, soybeans, corn, and
for fresh and dry vegetables also fell, following March gains. On the
other hand, fluid milk prices advanced 8.1 percent in April, after
increasing 5.7 percent a month earlier. The indexes for alfalfa hay,
unprocessed finfish, and raw cane sugar turned up, following declines in
the previous month.
Prices for basic industrial materials decreased 2.6 percent in April,
after falling 1.3 percent in March. The leaf tobacco index dropped 24.2
percent, following an 11.9-percent fall in the prior month. Prices for
gold ores, iron and steel scrap, and pulpwood turned down in April. The
wastepaper index declined more than it did a month earlier. Prices for
phosphates and for hardwood logs, bolts, and timber rose less in April than
they did in the previous month. By contrast, the raw cotton index
decreased 7.7 percent, after dropping 16.4 percent in March. Prices for
copper base scrap also fell less than they did in the prior month. The
indexes for aluminum base scrap and cattle hides rose more than they did in
March.
Net output price indexes for mining, manufacturing, and services industries
Mining. The Producer Price Index for the Net Output of Total Mining
Industries advanced 1.1 percent in April, following a 5.4-percent drop in
March. (Net output price indexes are not seasonally adjusted.) Most of
April's upturn can be traced to a 1.6-percent rise in prices received by
the crude petroleum, natural gas, and natural gas liquids industry, which
followed a 6.9-percent decline in the prior month. The index for the
bituminous coal and lignite industry also turned up in April. By contrast,
prices received by the gold ores industry moved down 4.6 percent, after
increasing 2.9 percent in March. Prices received by the oil and gas
exploration services industry and the potash, soda, and borate minerals
industry also fell, following gains a month earlier. In April, the
Producer Price Index for the Net Output of Total Mining Industries stood at
132.2 (December 1984 = 100), 38.1 percent above its year-ago level.

Manufacturing. The Producer Price Index for the Net Output of Total
Manufacturing Industries rose 0.6 percent in April, after edging down 0.1
percent in March. Leading this reversal, prices received by the petroleum
refining and related products industry group jumped 6.3 percent, following
a 4.2-percent dip in the previous month. The index for the measuring and
controlling instruments industry group also turned up in April. Prices
received by the machinery (except electrical) industry group advanced,
after showing no change a month earlier, while the index for the printing
and publishing industry group increased more than it did in the prior
month. On the other hand, prices received by the food and kindred products
industry group rose 0.6 percent, following a 1.0-percent gain in March.
The indexes for the chemicals and allied products and the furniture and
fixtures industry groups turned down in April. Prices received by the
transportation equipment and the lumber and wood products (except
furniture) industry groups advanced less in April than they did in the
previous month. In April, the Producer Price Index for the Net Output of
Total Manufacturing Industries stood at 135.4 (December 1984 = 100), 2.1
percent above its year-ago level.
Services. Among service industries in April, prices increased for property
and casualty insurance, skilled and intermediate care facilities, offices
of physicians, general medical and surgical hospitals, life insurance
carriers, and prepackaged software. By contrast, prices received by the
operators and lessors of nonresidential buildings, the passenger car
rental, the telephone communications (except radiotelephone), and the
scheduled air transportation industries fell in April.
*****
Producer Price Index data for May 2001 will be
released on Thursday, June 14, 2001 at 8:30 a.m. (E.D.T.)
One-Month Lag in Producer Price Indexes for Liquefied Petroleum Gas to be
Removed Effective with Data for July 2001
Effective with the release of data for July 2001, the 1-month lag in
the Producer Price Index (PPI) for Liquefied Petroleum Gas, commodity code
05-32, will be eliminated. Since 1971, the liquefied petroleum gas index
has been calculated with prices that lag behind the index reference date by
one month. For example, the Producer Price Index for January contains
liquefied petroleum gas prices for December.
In order to eliminate this lag, the Bureau of Labor Statistics will
utilize the natural gas liquids price data published by the Oil Price
Information Service (OPIS) to estimate the PPI. These data will be used in
the first-released index for liquefied petroleum gas. As is customary

practice, a revised PPI for Liquefied Petroleum Gas will be published four
months later. At that time, the interim estimates of price movement using
OPIS data will be replaced with prices from the PPI sample.
The July 2001 PPI for Liquefied Petroleum Gas to be released on August
10 will reflect the prices for this commodity as of July 2001. Indexes
prior to July will continue to represent liquefied petroleum gas prices
with a 1-month lag. As a result of this modification, the July 2001
percent change for the liquefied petroleum gas index will represent a 2month (May to July) price movement.
For more information, call the Section of Index Analysis and Public
Information at 202-691-7705.

Comprehensive relative importance figures are initially computed
after the publication of December indexes and are recalculated
after final December indexes are available. The first-published
and final December relative importances initially appear,
respectively, in the release tables containing January and May data.
The indexes for December 2000 have been recalculated to incorporate
late reports and corrections by respondents. All indexes
are subject to revision 4 months after original publication.

Technical Note
Brief Explanation of Producer Price Indexes
The term Producer Price Index (PPI) refers to a family of indexes that
measure the average change over time in the selling prices received by

domestic producers of goods and services. PPIs measure price change from
the perspective of the seller. This contrasts with other measures, such as
the Consumer Price Index (CPI); CPIs measure price change from the
purchaser's perspective. Sellers' and purchasers' prices may differ due to
government subsidies, sales and excise taxes, and distribution costs.
More than 10,000 PPIs for individual products and groups of products
are released each month. PPIs are available for the products of virtually
every industry in the mining and manufacturing sectors of the U.S. economy.
New PPIs are gradually being introduced for the products of industries in
the transportation, utilities, trade, finance, and services sectors of the
economy.
More than 100,000 price quotations per month are organized into three
sets of producer price indexes: (1) stage-of-processing indexes; (2)
commodity indexes; and (3) indexes for the net output of industries and
their products. The stage-of-processing structure (tables 1, 2, and 5)
organizes products by class of buyer and degree of fabrication. The
commodity structure (tables 2 and 3) organizes products by similarity of
end-use or material composition. The entire output of various industries
is sampled to derive price indexes for the net output of industries and
their products (table 4).
Within the stage-of-processing system, finished goods are commodities
that will not undergo further processing and are ready for sale to the
final demand user, either an individual consumer or business firm.
Consumer foods include unprocessed foods such as eggs and fresh vegetables,
as well as processed foods such as bakery products and meats. Other
finished consumer goods include durable goods such as automobiles,
household furniture, and appliances; and nondurable goods such as apparel
and home heating oil. Capital equipment includes producer durable goods
such as heavy motor trucks, tractors, and machine tools.
The stage-of-processing category for intermediate materials, supplies,
and components consists partly of commodities that have been processed but
require further processing. Examples of such semifinished goods include
flour, cotton yarn, steel mill products, and lumber. The intermediate
goods category also encompasses nondurable physically complete items
purchased by business firms as inputs for their operations. Examples
include diesel fuel, belts and belting, paper boxes, and fertilizers.
Crude materials for further processing are products entering the
market for the first time that have not been manufactured or fabricated and
that are not sold directly to consumers. Crude foodstuffs and feedstuffs
include items such as grains and livestock. Examples of crude nonfood

materials include raw cotton, crude petroleum, coal, hides and skins, and
iron and steel scrap.
Producer price indexes for the net output of industries and their
products are grouped according to the Standard Industrial Classification
(SIC). Industry price indexes are compatible with other economic time
series organized by SIC codes, such as data on employment, wages, and
productivity. Table 4 lists indexes for the net output of major mining and
manufacturing industry groups at the 2-digit level.
Producer price indexes are based on selling prices reported by
establishments of all sizes selected by probability sampling, with the
probability of selection proportionate to size. Individual items and
transaction terms from these firms are also chosen by probability
proportionate to size. BLS strongly encourages cooperating companies to
supply actual transaction prices at the time of shipment to minimize the
use of list prices. Prices are normally reported by mail questionnaire for
the Tuesday of the week containing the 13th.
Price data are provided on a voluntary and confidential basis; no one
but sworn BLS employees are allowed access to individual company price
reports. The Bureau publishes price indexes instead of unit dollar prices.
All producer price indexes are routinely subject to revision once, 4 months
after original publication, to reflect the availability of late reports and
corrections by respondents.
The BLS periodically updates the PPI sample of survey respondents to
better reflect current conditions when the structure, membership,
technology, or product mix of an industry shifts significantly and to
spread reporting burden among smaller firms. Results of these resampling
efforts are incorporated into the PPI every January and July.
As part of an ongoing effort to expand coverage to sectors of the
economy other than mining and manufacturing, an increasing number of
service sector industries have been introduced into the PPI. The following
list of recently introduced service industries includes the month in which

Weights for most traditional commodity groupings of the PPI, as well
as all indexes (such as stage-of-processing indexes) calculated from
traditional commodity groupings, currently reflect 1992 values of shipments
as reported in the Census of Manufactures and other sources. From January
1992 through December 1995, PPI weights were derived from 1987 shipment
values. Industry indexes shown in table 4 are also now calculated with
1992 net output weights. This periodic update of the value weights used to
calculate the PPI is done to more accurately reflect changes in production
and marketing patterns in the economy.
Net output values of shipments are used as weights for industry
indexes. Net output values refer to the value of shipments from
establishments in one industry to establishments classified in another
industry. However, weights for commodity price indexes are based on gross
shipment values, including shipment values between establishments within
the same industry. As a result, broad commodity grouping indexes such as
the all commodities index are affected by the multiple counting of price
change at successive stages of processing, which can lead to exaggerated or
misleading signals about inflation. Stage-of-processing indexes partially

correct this defect, but industry indexes consistently correct for this at
all levels of aggregation. Therefore, industry and stage-of-processing
indexes are more appropriate than broad commodity groupings for economic
analysis of general price trends.
Effective with publication of January 1988 data, many important PPI
series (including stage-of-processing groupings and most commodity groups
and individual items) were placed on a new reference base, 1982=100. From
1971 through 1987, the standard reference base for most PPI series was
1967=100. Except for rounding differences, the shift to the new reference
base did not alter any changes to previously published percent changes for
affected PPI series. (See "Calculating Index Changes," below.) The new
reference base is not used for indexes with a base later than December
1981, nor for indexes for the net output of industries and their products.
For further information on the underlying concepts and methodology of
the Producer Price Index, see chapter 14, "Producer Prices," in BLS
Handbook of Methods (April 1997), Bulletin 2490. Reprints are available
from the Bureau of Labor Statistics on request.
Calculating Index Changes
Each index measures price changes from a reference period which equals
100.0 (1982 or some later month). An increase of 5.5 percent from the
reference period in the Finished Goods Price Index, for example, is shown
as 105.5. This change can also be expressed in dollars as follows:
"Prices received by domestic producers of a systematic sample of finished
goods have risen from $100 in 1982 to $105.50 today." Likewise, a current
index of 90.0 would indicate that prices received by producers of finished
goods today are 10 percent lower than they were in 1982.
Movements of price indexes from one month to another are usually
expressed as percent changes rather than as changes in index points because
index point changes are affected by the level of the index in relation to
its base period, whereas percent changes are not. The example below shows
the computation of index point and percent changes.

Seasonally Adjusted and Unadjusted Data
Because price data are used for different purposes by different
groups, the Bureau of Labor Statistics publishes seasonally adjusted and
unadjusted changes each month. Seasonally adjusted data are preferred for
analyzing general price trends in the economy because they eliminate the
effect of changes that normally occur at about the same time and in about
the same magnitude every year--such as price movements resulting from
normal weather patterns, regular production and marketing cycles, model
changeovers, seasonal discounts, and holidays. For these reasons,
seasonally adjusted data more clearly reveal underlying cyclical trends.
Unadjusted data are of primary interest to users who need information
that can be related to actual dollar values of transactions. Individuals
requiring this information include marketing specialists, purchasing
agents, budget and cost analysts, contract specialists, and commodity
traders. It is the unadjusted data that are generally cited in escalating
long-term contracts such as purchasing agreements or real estate leases.

Parties, BLS Report 807, September 1991, available on request from BLS.)
