Description of Industries and Summary of Findings INDUSTRY 3792, TRAVEL TRAILERS AND CAMPERS This industry is made up of establishments primarily engaged in manufacturing travel trailers and campers for attachment to passenger cars or other vehicles, pickup coaches (campers) and caps (covers) for mounting on pickup trucks. Travel trailers are generally 35 feet long or less, 8 feet wide or less, and have storage facilities for water and waste. Establishments primarily engaged in manufacturing mobile homes are classified in industry 2451. 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 3792, Travel Trailers and Campers, had employment of 15.2 thousand. The employment figure was 12 percent below the 17.2 thousand reported in 1987. Compared with 1991, employment increased 28 percent. The 1991 data are based on the Census Bureau's annual survey of manufactures (ASM), which is a sample survey conducted each year between censuses. The leading States in employment in 1992 were Indiana, California, Pennsylvania, and Kansas, accounting for approximately 57 percent of the industry's employment. These same States were the leaders in 1987. The total value of shipments for establishments classified in this industry was $2.1 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 3792 shipped $1.9 billion of travel trailers and campers products considered primary to the industry, $100.7 million of secondary products, and had $102.6 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 95 percent (specialization ratio). In 1987, the specialization ratio was 94 percent. Establishments in this industry also accounted for 93 percent of products considered primary to the industry no matter where they were actually produced (coverage ratio). In 1987, the coverage ratio was 88 percent. The products primary to industry 3792, no matter in what industry they were produced, appear in file MC92F6A and aggregate to $2.0 billion. For further explanation of specialization and coverage ratios, see file MC92F5B and the appendixes. The total cost of materials, services, and fuels and energy used by establishments classified in the travel trailer and camper industry amounted to $1.3 billion. Data on specific materials consumed appear in file MC92F7. Single-establishment companies in this industry with less than 5 employees were excluded from the mail portion of the census. The data for these establishments (and a small number of larger establishments whose reports were not received at the time the data were tabulated) were obtained from administrative records of other agencies or developed from industry averages. These establishments accounted for 7 percent of the total value of shipments. INDUSTRY 3795, TANKS AND TANK COMPONENTS This industry is made up of establishments primarily engaged in manufacturing complete tanks, specialized components for tanks, and self- propelled weapons. Establishments primarily engaged in manufacturing military vehicles, except tanks and self-propelled weapons, are classified in industry group 371, and those manufacturing tank engines are classified in industry group 351. 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 3795, Tanks and Tank Components, had employment of 9.8 thousand. The employment figure was 41 percent below the 16.7 thousand reported in 1987. The leading States in employment in 1992 were California, Michigan, Ohio, and Pennsylvania. These same States were the leaders in 1987. The total value of shipments for establishments classified in this industry was $2.0 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 3795 shipped $1.9 billion of tanks and tank components products considered primary to the industry, $51.2 million of secondary products, and had $45.1 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 97 percent (specialization ratio). Establishments in this industry also accounted for 77 percent of products considered primary to the industry no matter where they were actually produced (coverage ratio). The products primary to industry 3795, no matter in what industry they were produced, appear in file MC92F6A and aggregate to $2.5 billion. For further explanation of specialization and coverage ratios, see file MC92F5B and the appendixes. The total cost of materials, services, and fuels and energy used by establishments classified in the tanks and tank components industry amounted to $931.3 million. Data on specific materials consumed appear in file MC92F7. No establishments in this industry were excluded from the mail portion of the census. However, for a small number of establishments, reports were not received at the time the data were tabulated. For these establishments data were obtained from administrative records of other agencies or developed from industry averages. These establishments accounted for less than 1 percent of the total value of shipments. INDUSTRY 3799, TRANSPORTATION EQUIPMENT, N.E.C. This industry is made up of establishments primarily engaged in manufacturing transportation equipment, not elsewhere classified. Establishments primarily engaged in manufacturing industrial trucks, tractors, trailers, and stackers are classified in industry 3537, and those manufacturing children's vehicles except bicycles are classified in industry 3944. 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 3799, Transportation Equipment, N.E.C., had employment of 19.5 thousand. The employment figure was 27 percent above the 15.4 thousand reported in 1987. Compared with 1991, employment increased 21 percent. The 1991 data are based on the Census Bureau's annual survey of manufactures (ASM), which is a sample survey conducted each year between censuses. The leading States in employment in 1992 were Georgia, Michigan, Minnesota, and Oklahoma. This represents a shift from 1987 when Georgia, Minnesota, Nebraska, and Texas were the leading States. The total value of shipments for establishments classified in this industry was $3.1 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 3799 shipped $2.7 billion of transportation equipment, not elsewhere classified, products considered primary to the industry, $252.3 million of secondary products, and had $167.7 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 91 percent (specialization ratio). In 1987, the specialization ratio was 94 percent. Establishments in this industry also accounted for 94 percent of products considered primary to the industry no matter where they were actually produced (coverage ratio). In 1987, the coverage ratio also was 94 percent. The products primary to industry 3799, no matter in what industry they were produced, appear in file MC92F6A and aggregate to $2.8 billion. For further explanation of specialization and coverage ratios, see file MC92F5B and the appendixes. The total cost of materials, services, and fuels and energy used by establishments classified in the transportation equipment, not elsewhere classified, industry amounted to $2.0 billion. Data on specific materials consumed appear in file MC92F7. Single-establishment companies in this industry with less than 5 employees were excluded from the mail portion of the census. The data for these establishments (and a small number of larger establishments whose reports were not received at the time the data were tabulated) were obtained from administrative records of other agencies or developed from industry averages. These establishments accounted for 16 percent of the total value of shipments.
