Labor productivity--as measured by output per employee hour--has been updated through 1993 for nearly all of the industries measured by BLS. Additionally, most of the measures in the nonmanufacturing sector, which includes mining, transportation, communications, utilities, trade, and services, have been updated to 1994. Manufacturing In the manufacturing sector, labor productivity increased in 1993 in 77 of the 104 industries measured. Productivity rose in 1992 in 80 of those same industries. (1994 productivity data are not available for the manufacturing sector. See note on page 3.) In motor vehicles and equipment, output per hour advanced by 1.2 percent in 1993, following an 8.0 percent gain in 1992. The aircraft industry also recorded a much smaller increase in labor productivity (0.5 percent) in 1993 compared with 1992 (8.6 percent). In contrast, the steel industry posted a higher rate of productivity growth in 1993 than in the preceding year; output per hour jumped by 12.3 percent in 1993, after growing by 8.8 percent the year before. (See table 1.) Transportation, communications and utilities Among the four industries in transportation, communications, and utilities updated to 1994, productivity advanced in all except one. (See table 2.) In the previous year, all four of those industries had productivity gains. The rates of productivity change in 1994 were 5.9 percent in electric utilities, 1.8 percent in air transportation, 0.9 percent in telephone communications, and -4.5 percent in gas utilities. -2- Trade Productivity grew in 1994 in 13 of the 20 industries that BLS measures in the trade sector, compared with 12 in 1993. The trade sector included the three industries with the highest productivity increases in 1994 among all of the measured industries: Men's and boys' clothing stores (19.4 percent), radio, television and computer stores (15.1 percent), and household appliance stores (10.2 percent). The biggest drop in output per hour in 1994 also occurred in one of the trade industries--variety stores, which registered a decline of 8.9 percent. Services The three industries in services with 1994 data available each recorded a substantial productivity increase from the previous year. The productivity growth rates were 7.6 percent in automotive repair shops, 4.3 percent in beauty shops, and 3.3 percent in hotels and motels. Among the three industries, only automotive repair shops had experienced growth in labor productivity in 1993. Mining Of the four mining industries updated to 1994, three posted a rise in output per hour. Each of those four industries had recorded a gain in 1993. The largest productivity increase in mining in 1994 was in crude petroleum and natural gas production, which registered a jump of 6.2 percent. New Industry Statistics on labor productivity were developed for the miscellaneous shopping goods industry, a retail trade industry that includes sporting goods and bicycle shops, book stores, and jewelry stores. In 1994, the miscellaneous shopping goods industry, which employs over 800,000 people, experienced a gain in output per hour of 1.6 percent. The increase resulted from a rise in output of 4.1 percent and an increase in hours of all persons of 2.5 percent. From 1977 to 1994, labor productivity in the industry climbed by 1.3 percent per year on average. Additional Measures Tables 1 and 2 contain year-to-year changes in labor productivity for distinct industries. In addition, BLS measures productivity for broader industries; long-term trends for all 176 industries are shown in table 3. In the past, BLS has published a second set of productivity measures for three industries (SICs 101, 102, and 4011) that were calculated with alternative measures of output. These measures are no longer published, but are available upon request. -3- Revisions Earlier this year, BLS adopted a new methodology for computing output indexes for its measures of industry labor productivity. Previously, output indexes had been computed utilizing base-year employee-hour weights to aggregate products of the industry. In the new methodology, an index of industry output is developed by computing a weighted average of the growth rates of the various industry products between two time periods, with weights based on the products' shares in industry value of production in the two periods. For a complete discussion of the method, see BLS modernizes industry labor productivity program, in the July 1995 Monthly Labor Review. The new procedure was used to revise historical industry labor productivity indexes, as well as to generate the latest productivity statistics. However, most of the revisions to long-term productivity trends were small. Indexes of productivity by industry also have been revised from 1987 forward to reflect the incorporation of data from the 1992 Economic Censuses. As a result of the new methodology and data, most of the industry labor productivity indexes in BLS Bulletin 2461, Productivity Measures for Selected Industries and Government Services, published in May 1995, have been revised. The revised series can be obtained in several forms: Data printouts (202-606-5618), data diskettes (202-606-7789), or from the World Wide Web (http://stats.bls.gov). Future Update Measures of labor productivity for manufacturing industries have been updated only to 1993 because BLS has not yet received data from the Census Bureau's 1994 Annual Survey of Manufactures (ASM). Currently, BLS anticipates receiving the ASM data in the next few months and then releasing 1994 productivity indexes for manufacturing industries shortly thereafter. Federal Productivity Measurement BLS is terminating the Federal Productivity Measurement Program, due to budget reductions. This program measured productivity in 60 federal government agencies, covering approximately two-thirds of the federal executive branch civilian work force. The final publication of results from the program-- covering fiscal years 1967-94--will occur early in 1996. -4- Notes The productivity measures in this release describe the relationship between output and the labor time involved in its production. They show the changes from period to period in the amount of goods and services produced per hour. Although these measures relate output to hours of employees or all persons engaged in an industry, they do not measure the specific contribution of labor, capital, or any other factor of production. Rather, they reflect the joint effects of many influences, including changes in technology; capital investment; level of output; utilization of capacity, energy, and materials; the organization of production; managerial skill; and the characteristics and effort of the workforce.
