=>PURPOSE This numerical list includes the principal products and services of the manufacturing and mining industries in the United States. The data for these products and services were collected in the 1992 Census of Manufactures on 213 long forms (MC - 2001 through MC - 3912) and 78 short report forms (MC - 2071 through MC - 3975) and in the 1987 Census of Mineral Industries on 10 long (MC - 1001 through MC - 1403) and 2 short forms (MC - 1371 and MC - 1471). Each report form covers one industry or more and includes a product inquiry which lists the primary products of the industries as well as the chief secondary products frequently reported by establishments classified in the industries on that report form. Products and services are arrayed generally in ascending seven-digit numerical order followed by alphabetical characters within their respective five-digit codes (product classes), the product classes in order within their four-digit codes (industries), and the industries within their three- digit industry groups and two-digit major groups. Major groups, industry groups, and industries, as presented in this manual, are in accord with both title and content of the Standard Industrial Classification Manual: 1987 edition, published by the Office of Management and Budget. In addition to the more than 6,300 products for which information is collected primarily in the censuses of manufactures and mineral industries, there are over 4,500 products for which information is collected monthly, quarterly, and annually in the Census Bureau's Current Industrial Reports (CIR) program. Where CIR product detail is available, the census report requests only broad aggregates that can be "tied in" with the product detail in the CIR program. =>PRODUCT CODING SYSTEM Each product or service is assigned a seven-digit code. The product coding structure represents an extension by the Bureau of the Census of the four- digit industrial classification of the manufacturing and mining industries as defined in the Standard Industrial Classification (SIC) System. The SIC, developed under the direction of the Office of Management and Budget by the Technical Committee on Industrial Classification, classifies establishments to the four-digit industry level by their primary type of activity. The classification system operates so that the industrial coverage is progressively narrower with the successive addition of digits. This is illustrated as follows: SIC Code Level Description 20 Major group Food and kindred products 202 Industry group Dairy products 2022 Industry Cheese, natural, and processed 20225 Product class Cheese substitutes 20225 11 Product Products substituting for natural cheese =>COMPARABILITY BETWEEN 1992 AND 1987 This manual attempts to preserve the historical comparability between the 1992 and 1987 censuses for product classes and product codes in file MN92NCOM.dbf. When indexed using MN92NC92.ndx, file MN92NCOM.dbf presents the linkage from 1992 to 1987. When indexed using MN92NC87.ndx, it provides the mirror-type linkage from 1987 to 1992. =>CURRENT INDUSTRIAL REPORTS (CIR) The 1992 Census of Manufactures, as in earlier censuses, utilizes the tieline product method for reporting summary information in the census where product detail is being reported for the same period in a CIR or, in a few instances, surveys conducted by other Federal Government agencies. The product detail that is collected monthly, quarterly, or annually in the CIR is not duplicated in the census of manufactures. Instead a single (tieline) code is collected in the census that corresponds to the sum of the detail appearing if the CIR is used. For tielines related to the CIR, the product detail covered in the commodity surveys comprises, additionally, more than 4,500 product lines, each coded to the seven-digit level. The products collected in the CIR are shown in files MN92NUM.dbf and MN92NUB.dbf, "Product Descriptions in Current Industrial Reports that Relate to Tielines in 1992 Census of Manufactures" and "Product Descriptions in Production-Only Current Industrial Reports." The product coding used for the census and for the CIR constitutes a body of product codes slightly less than 11,000 items. =>FORMAT OF MANUAL In this numerical list, there is one product code column that corresponds to product codes used in the 1992 publications and are based on the 1987 SIC structure. Appended to each seven-digit product code is an eighth digit called the "check digit" used to verify the keying of product codes for computer processing. The check digit is developed from the seven-digit product code itself but is not part of the product code. The sixth and seventh digits of the product code taken together are unique and identify the product. Occasionally, the sixth digit will be similar for a group of related products within the product class but the sixth digit by itself is not significant. These products and services codes are arrayed (generally) in ascending numerical order followed by alphabetical characters within their respective five-digit product classes, the product classes within their four-digit industries, the industries within their three-digit industry groups, and the industry groups within their two-digit major groups. Major groups, industry groups, and industries are titled in accordance with the short SIC titles shown in Part II, Numerical List of Short Titles, Standard Industrial Classification Manual, 1987 edition. Titles and descriptions of the five-digit product classes and seven-digit products have been developed by the Bureau of the Census. The titles of the two- to five-digit levels are shown in capital letters. To the right of each four-digit industry title is the number of the report form used in the censuses to collect the information for products and services of that industry (for example, MC-1001). The product code, check digit, product description, unit of measure for quantity data collected, and kinds of data collected are given for each product. (See abbreviations section for key to the abbreviations used for unit of quantity and data collected.) This manual contains seven dBase files that correspond to the main body and ten appendixes shown in the hard-copy publication. File MN92NUM.dbf and MN92NUB.dbf list the product detail brought into the census by both tielines to and special production-related surveys of the CIR. File MN92NCIR.dbf relates these Current Industrial Reports to their Census tielines. File MN92NUX.dbf contains the codes for the contract and miscellaneous receipts reported by manufacturing and mining establishments. File MN92N_G.dbf shows those products that are primary to more than one industry; that is, produced elsewhere but by a different process. File MN92N_H.dbf provides the list of Census product codes that relate to the U.S. International Trade Commission Report, "Synthetic Organic Chemicals." Finally, file MN92NCOM.dbf illustrates the relationship between the 1992 and 1987 product classes and product codes. =>CHANGES IN PRODUCT CLASSES For the 1992 Census of Manufactures, data were collected on 1,462 product classes compared with 1,446 in the 1987 census. =>ABBREVIATIONS The phrase "To be spec" indicates that the unit of measure is specified by the reporting establishment. The abbreviation "n.e.c." means not elsewhere classified. =>- Units of Measure bbls Barrel bd Board Btu British thermal unit co Consumed cu Cubic cwt Hundredweight doz Dozen equiv Equivalent fin Finished ft Feet gal Gallon hr Hour lum Lumber lb Pounds lin Linear mil Millions no Number oz Ounces qt Quarts sm Surface measure sngl Single sol Solids sq Square st Strength std Standard yd Yards =>- Data Collected C Consumption CC Circulation copies I Inventory (stock) ISV Interplant shipments (value) P Production (quantity) PC Produced and consumed (quantity) PV Production (value) R Receipts (value) RA Receipts from advertising RAC Receipts from advertising and copy sales RC Receipts from single copy sales RQ Receipts (quantity) RS Receipts from subscriptions and sales RSB Receipts from subscriptions S Shipments (quantity and value) SQ Shipments (quantity) SV Shipments (value) UO Unfilled orders (value) UOQ Unfilled orders (quantity) VW Value of work done
