Description of Industries and Summary of Findings INDUSTRY 3621, MOTORS AND GENERATORS This industry is made up of establishments primarily engaged in manufacturing electric motors (except engine starting motors) and power generators; motor generator sets; railway motors and control equipment; and motors, generators, and control equipment for gasoline, electric, and oil- electric buses and trucks. Establishments primarily engaged in manufacturing turbogenerators are classified in industry 3511; those manufacturing starting motors and battery charging generators for internal combustion engines are classified in industry 3694; and those manufacturing generators for welding equipment are classified in industry 3548. Products of this industry also are collected in the Current Industrial Report (CIR) MA-36H, Motors and Generators. For information regarding the CIR, see Contacts for Data Users at the end of the Census of Manufactures section. The 1992 definition of this industry is the same as that used in the 1987 Standard Industrial Classification (SIC) system. The SIC number and title also are the same. In the 1992 Census of Manufactures, Industry 3621, Motors and Generators, had employment of 67.9 thousand. The employment figure was 9 percent below the 74.6 thousand reported in 1987. The leading States in employment in 1992 were Wisconsin, Missouri, Arkansas, and Ohio, accounting for approximately 34 percent of the industry's employment. This represents a shift from 1987 when Ohio, Arkansas, Wisconsin, and New York were the leading States. The total value of shipments for establishments classified in this industry was $8.0 billion. Establishments in virtually all industries ship secondary products as well as products primary to the industry in which they are classified and have some miscellaneous receipts, such as resales and contract receipts. Industry 3621 shipped $7.5 billion of motors and generators considered primary to the industry, $331.6 million of secondary products, and had $240.1 million of miscellaneous receipts, resales, and contract work. Thus, the ratio of primary products to the total of both secondary and primary products shipped by establishments in this industry was 96 percent (specialization ratio). In 1987, the specialization ratio was 95 percent. Establishments in this industry also accounted for 88 percent of products considered primary to the industry no matter where they were actually produced (coverage ratio). In 1987, the coverage ratio was 89 percent. The products primary to industry 3621, no matter in what industry they were produced, appear in file MC92F6A and aggregate to $8.5 billion. For further explanation of specialization and coverage ratios, see file MC92F5B and the appendixes.
