Description of Industries and Summary of Findings INDUSTRY 3052, RUBBER AND PLASTICS HOSE AND BELTING This industry is made up of establishments primarily engaged in manufacturing rubber and plastics hose and belting, including garden hose. Establishments primarily engaged in manufacturing rubber tubing are classified in industry group 306; those manufacturing plastics tubing are classified in industry 3082; and those manufacturing flexible metallic hose are classified in industry 3599. 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 3052, Rubber and Plastics Hose and Belting, had employment of 19.9 thousand. The employment figure was 14 percent below the 23.2 thousand reported in 1987. Compared with 1991, employment decreased 6 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 Nebraska, Ohio, and North Carolina. These same States were the leaders in 1987. The total value of shipments for establishments classified in this industry was $2.6 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 3052 shipped $2.4 billion of rubber and plastics hose and belting considered primary to the industry, $131.8 million of secondary products, and had $38.8 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 94 percent. The products primary to industry 3052, no matter in what industry they were produced, appear in file MC92F6A and aggregate to $2.6 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 rubber and plastics hose and belting industry amounted to $1.3 billion. Data on specific materials consumed appear in file MC92F7. Single-establishment companies in this industry with less than 15 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 6 percent of the total value of shipments. INDUSTRY 3053, GASKETS, PACKING, AND SEALING DEVICES This industry is made up of establishments primarily engaged in manufacturing gaskets, gasketing materials, compression packings, mold packings, oil seals, and mechanical seals. It also includes establishments primarily engaged in manufacturing gaskets, packing, and sealing devices made of leather, rubber, metal, asbestos, and plastics. 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 3053, Gaskets, Packing, and Sealing Devices, had employment of 32.4 thousand. The employment figure was 14 percent above the 28.4 thousand reported in 1987. The leading States in employment in 1992 were Illinois, California, Texas, and Ohio, accounting for approximately 42 percent of the industry's employment. These same States were the leaders in 1987 when they also accounted for 42 percent of the industry's employment. The total value of shipments for establishments classified in this industry was $3.3 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 3053 shipped $2.9 billion of gaskets, packing, and sealing devices considered primary to the industry, $252.7 million of secondary products, and had $175.4 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 92 percent (specialization ratio). In 1987, the specialization ratio was 95 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 also was 93 percent. The products primary to industry 3053, no matter in what industry they were produced, appear in file MC92F6A and aggregate to $3.1 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 gaskets, packing, and sealing devices industry amounted to $1.4 billion. Data on specific materials consumed appear in file MC92F7. Single-establishment companies in this industry with less than 10 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 6 percent of the total value of shipments.
