Description of Industries and Summary of Findings INDUSTRY 3291, ABRASIVE PRODUCTS This industry is made up of establishments primarily engaged in manufacturing abrasive grinding wheels of natural or synthetic materials, abrasive-coated products, and other abrasive products. The cutting of grindstones, pulpstones, and whetstones at the quarry is classified in Division B, Mining. 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 3291, Abrasive Products, had employment of 21.5 thousand. The employment figure was 8 percent below the 23.4 thousand reported in 1987. The leading States in employment in 1992 were Massachusetts, Ohio, and New York, accounting for approximately 36 percent of the industry's employment. The leading states in 1987 were Massachusetts, New York, Ohio, and Minnesota. The total value of shipments for establishments classified in this industry was $3.7 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 3291 shipped $3.0 billion of abrasive products considered primary to the industry, $546.7 million of secondary products, and had $158.0 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 85 percent (specialization ratio). In 1987, the specialization ratio was 82 percent. Establishments in this industry also accounted for 95 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 3291, no matter in what industry they were produced, appear in file MC92F6A and aggregate to $3.2 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 abrasive products industry amounted to $1.7 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 5 percent of the total value of shipments. INDUSTRY 3292, ASBESTOS PRODUCTS This industry is made up of establishments primarily engaged in manufacturing asbestos textiles, asbestos building materials, except asbestos paper, insulating materials for covering boilers and pipes, and other products composed wholly or chiefly of asbestos. Establishments primarily engaged in manufacturing asbestos paper are classified in industry 2621, and those manufacturing gaskets and packing are classified in industry 3053. 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 3292, Asbestos Products, had employment of .7 thousand. The employment figure was 82 percent below the 4.0 thousand reported in 1987. As of 1992, Federal Legislation has prohibited production of some asbestos products and severely restricted production of others. The Annual Survey of Manufacturers (ASM) sample and other factors tended to maintain the data for this industry at too high a level for 1988 through 1991. Applying the change shown from 1991 to 1992 over the entire 1987 to 1992 period would provide more accurate data for the decrease in this industry. 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 3292 shipped 41.0 million of asbestos products considered primary to the industry. The total value of shipments for establishments classified in this industry was $74.0 million. Establishments in this industry also accounted for 56 percent of products considered primary to the industry no matter where they were actually produced (coverage ratio). In 1987, the coverage ratio was 90 percent. The products primary to industry 3292, no matter in what industry they were produced, appear in file MC92F6A and aggregate to $72.7 million. 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 asbestos products industry amounted to $30.0 million. 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 3 percent of the total value of shipments. INDUSTRY 3295, MINERALS, GROUND OR TREATED This industry is made up of establishments operating without a mine or quarry and primarily engaged in crushing, grinding, pulverizing, or otherwise preparing clay ceramic and refractory minerals; barite; and miscellaneous nonmetallic minerals, except fuels.

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 also was 96 percent. Establishments in this industry also accounted for 96 percent of products considered primary to the industry no matter where they were actually produced (coverage ratio).
