The sample design for the 1951 Annual Survey of Manufactures was revised to correct the undercoverage in this industry. 10These estimates are subject to sampling variations. The standard errors are 3 percent for "Number of establishments;" 3 percent for "All employees;" and 2 percent for "Value added." 11These estimates are subject to sampling variations. The standard errors are 2 percent for "Number of establishments;" 2 percent for "All employees;" and 2 percent for "Value added." 12These estimates are subject to sampling variations. The standard errors are 10 percent for "Number of establishments;" 8 percent for "All employees;" and 7 percent for "Value added." 13Includes privately owned and/or operated establishments classified in Industry Group 19 (Ordnance and accessories). Government owned and operated establishments are excluded from the annual survey. 14These estimates are subject to sampling variations. The standard errors are 5 percent for "Number of establishments;" 6 percent for "All employees;" and 30 percent for "Value added." 15 Administrative office and auxiliary unit employment is based on the number of employees reported as of mid-March under the Old-Age and Survivors Insurance program. The administrative and auxiliary employment and pay roll figures for 1950 were also used for 1951, as 1951 OASI program data were not available for this publication. 16Includes data for Sausage casings (Industry 2014). 17Includes data for Shingle mills (Industry 2423). 18Data for 1951, and 1950, for this industry, are not strictly comparable. For 1950, establishments engaged in the production of wood or metal storm-sash, and wood or metal combination-screen-and-storm-sash and doors, were classified in Industry 2561 (Window and door screens). For 1951, they are classified in Industry 2431 (Millwork Plants), if the products are of wood; in Industry 3442 (Metal doors, sash and trim), if the products are of metal. 19Includes data for Building-paper and Building-board mills (Industry 2613). 20These estimates are subject to sampling variations. The standard errors are 20 percent for "Number of establishments;" 20 percent for "All employees;" and 20 percent for "Value added." 21These estimates are subject to sampling variations. The standard errors are 30 percent for "Number of establishments;" 20 percent for "All PART II PRODUCT STATISTICS PRODUCTION AND SHIPMENTS OF SELECTED PRODUCTS FOR THE UNITED STATES: 1951 AND 1950 The 1947 Census of Manufactures publications included statistics for approximately 6, 100 individual products. Similar figures had been published in the 1939 Census volumes for about 4,000 products. For many years, the Bureau of the Census has conducted monthly, quarterly, and annual surveys to obtain similar data for intercensal years on those commodities for which more frequent statistics were urgently needed and for which there was no other reliable source of such information. For 1951, the Census Bureau was conducting 66 such commodity surveys which yielded detailed statistics for about 2, 300 products. Statistics for groups of commodities, based on these surveys, are regularly published in the Census "Facts for Industry" series of releases and corresponding annual summaries. Part II of the present volume brings together in a single place for the first time the annual production and shipments statistics available from these surveys. It includes comparable figures for 1951 and 1950. These figures are generally comparable with the 1947 and 1939 commodity statistics published in table 6 of Volume II, Statistics by Industry; and in the Product Supplement volume of the 1947 Census of Manufactures. The 6, 100 individual products for which 1947 Census data were published, have been grouped into approximately 1,000 product classes. Data on the value of shipments of these product classes are obtained in the Annual Survey of Manufactures, and are summarized in Part I, Chap. III, insofar as they can be published. The 1951 Census commodity program included statistics for 236 product classes in whole or in part, and all products in Part II have been grouped into these classes. If data are not available for every product in a product class, the word "Selected" has been added after the product class title. Totals for a product class are shown only if data for all component products are available. The product classes usually produced in each major industry group are shown together in the following table, thus dividing the table into 20 sections corresponding to the 20 major manufacturing industry groups for which statistics have been included in Part I of this volume. The commodity statistics included in Part II represent, insofar as they are available in the commodity surveys, quantity of production and quantity and value of shipments. In a few cases, other information is included, such as production by type of material used (cotton, rayon, nylon, or wool) and figures for commodities produced and consumed by the same company. These figures represent summaries for the United States during the entire year. Tabulations by State, by month, or by quarter are also available for some of the commodities. Such information is published in the separate "Facts for Industry" releases for the specific commodity groups which are referred to in the footnotes of the following table. Annual summary releases are available for each of these commodity groups. In general, the commodity data represent complete coverage of the items for which statistics are shown. Footnotes to the table indicate the extent to which there were limitations on coverage. A few of the commodity figures were derived from sample surveys and, in such cases, the adequacy of the sample is discussed in a footnote to the table. The monthly, quarterly, and annual manufactures statistics program of the Bureau of the Census was begun early in this century. Over the years, surveys have been added and discontinued to meet the needs of industry and other users of the statistics. In addition to Census commodity statistics, other Federal Agencies and private industry collect selected commodity data. The first footnote of each section of the following table includes references to any other Federal government sources that are available for additional information on the products of that section. 175 1In addition to the Bureau of the Census statistics shown in this table, data are available for a number of food products from surveys conducted by other Government agencies including: (1) The Department of Agriculture, which collects information on production of meats; milk, cream, cheese, and other dairy products; fruits, vegetables, and grains; fresh, dried, frozen, and liquid eggs; and sugar and sirup. (2) The Fish and Wildlife Service, Department of the Interior, which collects data on fresh, canned, cured, and frozen fish. (3) The Office of Domestic Commerce, Department of Commerce, which collects data on confectionery products, jams and preserves, and salad dressings. (4) The Bureau of Internal Revenue, Department of the Treasury, which collects data on the production of malt liquors, wines, and distilled liquors. 2Source: Facts for Industry Series M17A, Fats and Oils. These statistics represent all known factory producers of the items shown. 3 Source: Facts for Industry Series M16A, Flour Milling Products. These statistics represent the total production of all commercial flour mills in the United States. Approximately 97 percent of the totals were reported to the Bureau of the Census monthly by the 375 largest mills, which had a daily (24-hour) capacity of over 400 sacks in 1950. The balance was estimated for 1951 on the basis of 1950 data obtained in an annual survey of the smaller mills. "Source: Facts for Industry Series M16C Confectionery (Including Chocolate Products). These statistics are based on monthly reports from approximately 400 manufacturers of confectionery and competitive chocolate products accounting in 1950 for approximately 87 percent of the total dollar value of sales of such products. The reported figures were inflated to represent total sales of all known producers of confectionery and competitive chocolate products, except retail confectioners with a single business location. These shipment figures correspond to the product class "Confectionery, except solid chocolate bars" and parts of the product classes "Other chocolate and cocoa products, in boxes over 2-1/2 lbs." and "Other chocolate and cocoa products in boxes 2-1/2 lbs. or less."
