The Consumer Price Index for All Urban Consumers (CPI-U) rose 0.6 percent in April, before seasonal adjustment, to a level of 179.8 (1982- 84=100), the Bureau of Labor Statistics of the U.S. Department of Labor reported today. For the 12-month period ended in April, the CPI-U increased 1.6 percent.

The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) also increased 0.6 percent in April, prior to seasonal adjustment. The April level of 175.8 was 1.3 percent higher than the index in April 2001.

CPI for All Urban Consumers (CPI-U)

On a seasonally adjusted basis, the CPI-U increased 0.5 percent in April, following a 0.3 percent increase in March. The energy index advanced sharply for the second consecutive month--up 4.5 percent in April. The index for petroleum-based energy increased 9.4 percent, while the index for energy services was unchanged. The food index rose 0.1 percent in April. Grocery store food prices were unchanged after increasing 0.2 percent in each of the preceding two months. Fruit and vegetable prices, which rose sharply in the first three months of 2002, declined 1.8 percent in April. Excluding food and energy, the CPI-U rose 0.3 percent in April after increasing 0.1 percent in March. A larger increase in the index for shelter and an upturn in the index for tobacco and smoking products accounted for the acceleration in April.

See pages 4 through 6 for notes on changes introduced into the CPI in 2002 and for a note on a new supplemental index of consumer price change.

During the first four months of 2002, the CPI-U rose at a 3.8 percent seasonally adjusted annual rate (SAAR). This compares with an increase of 1.6 percent for all of 2001. The index for energy, which declined 13.0 percent in 2001, increased at a 28.0 percent SAAR in the first four months of 2002. Petroleum-based energy costs increased at a 77.5 percent annual rate, while charges for energy services declined at a 4.4 percent annual rate. The food index has increased at a 2.4 percent SAAR thus far this year, following a 2.8 percent rise for all of 2001. Excluding food and energy, the CPI-U advanced at a 2.4 percent SAAR in the first four months, following a 2.7 percent rise in all of 2001

The food and beverages index increased 0.1 percent in April. The index for food at home was unchanged in April, following a 0.2 percent rise in March. The index for fruits and vegetables, which had risen sharply in each of the first three months of 2002, declined 1.8 percent in April. Within the fruits and vegetables group, the indexes for fresh fruits and for fresh vegetables declined 2.5 and 2.7 percent, respectively, while prices for processed fruits and vegetables increased 1.0 percent. The indexes for dairy products and for meats, poultry, fish, and eggs also registered declines in April. Within the latter category, beef prices rose 0.3 percent, while pork and poultry prices fell 0.1 and 0.7 percent, respectively. The index for cereals and bakery products, which fell 0.1 percent in March, increased 0.3 percent in April, reflecting a sharp upturn in prices for flour and prepared flour mixes. The index for nonalcoholic beverages rose 0.4 percent and the index for other food at home increased 1.1 percent. The other two components of the food and beverages index--food away from home and alcoholic beverages-- increased 0.1 and 0.2 percent, respectively.

The index for housing rose 0.3 percent in April. Shelter costs, which rose 0.1 percent in March, advanced 0.4 percent in April. Within shelter, the indexes for rent rose 0.2 percent, owners' equivalent rent increased 0.3 percent, and the index for lodging away from home advanced 1.6 percent. The index for fuels and utilities increased 0.2 percent in April. The index for fuel oil rose 3.5 percent, following a 2.2 percent increase in March. In April, the index for natural gas rose 2.4 percent, while the index for electricity declined 0.7 percent. The index for household furnishings and operations declined 0.1 percent in April.

The transportation index, which rose 1.2 percent in March, advanced 1.7 percent in April. The increases in both months reflect the sharp runup in gasoline prices. The index for gasoline rose 8.0 and 10.1 percent in March and April, respectively. (Prior to seasonal adjustment, gasoline prices rose 9.7 and 12.8 percent, respectively, in March and April.) In April, the indexes for new vehicles and for used cars and trucks each declined for the fourth consecutive month, down 0.2 and 0.5 percent, respectively. During the last 12 months, the index for new vehicles has declined 1.6 percent and the index for used cars and trucks has fallen 4.9 percent. Airline fares increased for the fourth consecutive month--up. 0.9 percent in April--following declines in each of the last six months of 2001.

The index for apparel declined 0.6 percent in April, following increases of 0.5 and 1.2 percent in the preceding two months. (Prior to seasonal adjustment, apparel prices rose 0.5 percent, reflecting the remaining introduction of spring-summer wear.)

The medical care index rose 0.5 percent in April to a level 4.6 percent above its level a year ago. The index for medical care commodities--prescription drugs, nonprescription drugs, and medical supplies--increased 0.2 percent. The index for medical care services rose 0.6 percent in April. Charges for professional services rose 0.3 percent and those for hospital and related services increased 1.1 percent. The latter index has increased at an 11.7 percent SAAR in the first four months of 2002 and is 8.6 percent higher than its level in April 2001.

The index for recreation rose 0.3 percent in April. The index for admissions to movies, theaters, concerts, and sporting events rose 1.1 percent in April after advancing 0.9 percent in March.

Prices for personal computers and peripheral equipment continued to decline, down 0.9 percent in April and 27.8 percent during the last 12 months.

The index for other goods and services which declined 0.6 percent in March, rose 1.5 percent in April. Prices for cigarettes, which declined 3.8 percent in March, increased 6.8 percent in April, reflecting the pass through of a wholesale price increase, selected state tax increases, and a reduction in the discounting of selected major brands.

CPI for Urban Wage Earners and Clerical Workers (CPI-W)

On a seasonally adjusted basis, the CPI for Urban Wage Earners and Clerical Workers increased 0.6 percent in April.

Consumer Price Index data for May are scheduled for release on Tuesday, June 18, 2002, at 8:30 A.M. (EDT).

CPI (Old Weights)

For the first six months of 2002, BLS also will calculate Old Weights CPI-U and Old Weights CPI-W based on the 1993-95 expenditure pattern used in the CPI from 1998 through 2001. These Old Weight data are contained in tables 1(OW)-4(OW). From March to April 2002, the Old Weights CPI-U rose 0.6 percent and the Old Weights CPI-W rose 0.7 percent. Note these series are not seasonally adjusted.

Changes in the Consumer Price Index in 2002

Expenditure Weight Update

As announced in December 1998, the Bureau of Labor Statistics (BLS) has updated the consumption expenditure weights in the Consumer Price Index for all Urban Consumers (CPI-U) and in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) to the 1999-2000 period, effective with release of data for January 2002. The newer weights replace the 1993-95 weights, which were first used in the index effective with January 1998 data. Additionally, CPI expenditure weights will be updated at two-year intervals subsequent to the 2002 updating. Thus, for example, CPI expenditure weights will be updated to the 2001-02 period effective with release of CPI data for January 2004.

Historically, the introduction of a comprehensive new set of expenditure weights attached to the categories of goods and services in the CPI "market basket" has taken place in the context of the periodic major revisions of the index. Such major revisions have taken place approximately once each decade-in 1940, 1953, 1964, 1978, 1987 and, most recently, in 1998.

The goal in employing more current expenditure weights is to have the CPI reflect, as much as possible, the inflation currently experienced by consumers. More specifically, the use of more current weights will help to ensure that the relative importance of CPI item categories, such as food away from home, college tuition, or medical care services, more accurately reflects how consumers are allocating their spending.

Publication of Overlap CPIs

For the first six months of 2002, BLS will continue to calculate and publish selected CPI-U and CPI-W "overlap" indexes on a not seasonally adjusted basis. These indexes will be compiled using the 1993-95 expenditure pattern that was introduced into the CPI in 1998. Comparison of these index series to the corresponding updated series will enable users of the CPI to observe the effects of the expenditure weight change. The subsequent expenditure updates scheduled in 2004 and every two years thereafter also will be accompanied by the publication of overlap indexes for a six-month period using the previous expenditure pattern.

Publication of CPI for the Phoenix Area

Effective with release of the July 2002 Consumer Price Index (CPI), BLS will initiate publication of consumer price data specific to the Phoenix-Mesa, Arizona, Metropolitan Statistical Area. As with the national CPI and other local area CPIs, data will be published for each of two population groups, that for all urban consumers (CPI-U) and that for urban wage earners and clerical workers (CPI-W). The Phoenix-Mesa CPI will be published on a semi-annual basis with a reference base of December 2001 = 100. The same amount of item detail will be available for Phoenix- Mesa as is presently available for all other areas published on a semi- annual basis.

Change to Published Item Structure

Effective with release of the January 2002 CPI, BLS began publishing an item index for leased cars and trucks. This index series is available monthly at the U.S. City Average area level for both the CPI-U and CPI-W with a December 2001 = 100 reference base.

NOTE ON A NEW, SUPPLEMENTAL INDEX OF CONSUMER PRICE CHANGE

The Bureau of Labor Statistics will begin publishing a 1consumer price index (CPI) called the Chained Consumer Price Index for All Urban Consumers, effective with release of July data in August 2002. Designated the C-CPI-U, the index will supplement the existing indexes already produced by the BLS: the CPI for All Urban Consumers (CPI-U) and the CPI for Urban Wage Earners and Clerical Workers (CPI-W).

The C-CPI-U will employ a Tornqvist formula and utilize expenditure data in adjacent time periods in order to reflect the effect of any substitution that consumers make across item categories in response to changes in relative prices. The new measure, said to be a "superlative" index, is designed to be a closer approximation to a "cost-of-living" index than the present measures. The use of expenditure data for both a base period and the current period in order to average price change across item categories distinguishes the C-CPI-U from the existing CPI measures, which use only a single expenditure base period to compute the price change over time. In 1999, the BLS introduced a geometric mean estimator for averaging prices within most of the index's item categories in order to approximate the effect of consumers' responses to changes in relative prices within these item categories. The geometric mean estimator will be used in the C-CPI-U in the same item categories in which it is now used in the CPI-U and CPI-W. (See Monthly Labor Review, October 1998, pp. 3-7.)

Expenditure data required for the calculation of the C-CPI-U are available only with a time lag. Thus, the C-CPI-U will be issued first in preliminary form using the latest available expenditure data at that time and will be subject to two subsequent revisions. Accordingly, at the time of its introduction in August, "final" values of the C-CPI-U will be issued for the 12 months of 2000, "interim" values will be issued for the 12 months of 2001, and "initial" values will be issued for January-July 2of 2002. In February 2003, with release of the January 2003 index, revised interim indexes for the 12 months of 2002 will be published, and the index values for 2001 will be revised and will become final. Then, in February 2004, when the monthly expenditure data from calendar year 2002 become available, C-CPI-U indexes for the 12 months of 2002 will be issued in final form and values for the 12 months of 2003 will be revised and issued as interim. The C-CPI-U index revisions are expected to be small, but in principle each monthly index could be revised from its previously published level.

BLS previously has calculated superlative indexes on an experimental basis, although these are not comparable to the C-CPI-U in all computational details. (See, for example, Monthly Labor Review, December 1993, pp. 25-33.) Based on BLS research, the C-CPI-U is estimated to increase at an average annual rate of 0.1 to 0.2 percentage point less than the CPI-U.

The C-CPI-U will be issued for national averages only and will not be seasonally adjusted. It will employ a December 1999=100 reference base. Data for periods prior to December 1999 will not be calculated. The component series that will be published are listed below:

All items Medical care Food and beverages Medical care commodities Food Medical care services Food at home Recreation Food away from home Education and communication Alcoholic beverages Education Housing Communication Shelter Other goods and services Fuels and utilities Services Household furnishings Commodities and operations Durables Apparel Nondurables Transportation All items less food and energy Private transportation Energy Public transportation

These indexes will be published monthly in the CPI news release and the CPI Detailed Report, and the series will be available electronically at the same site as other CPI data: http://www.bls.gov/cpi/.
