The percentage standard errors shown in this column indicate the differences that can be expected, because of sampling fluctuations, between the estimates and comparable totals which would have been obtained from a complete canvass using the same procedures. The estimates will differ from the complete totals by less than: 1) The percentage shown: approximately 2 times out of 3. (ii) Twice the percentage shown: approximately 19 times out of 20. (iii) Three times the percentage shown: almost always. Standard errors of estimates are not available for 1952 data. 4Revised. "Data for 1951 and 1952 include the metals produced and consumed in the same establishment, whereas such metals are excluded for other years. The degree to which the 1951 and 1952 data are not comparable with 1950 and 1953 data can be estimated through the following ratios which are based on the 1950 data. The range is less than 5 percent except as follows: 5 percent but not more than 10 percent for industries 3542 and 3591; over 10 percent but not more than 20 percent for industries 3519, 3621, and 3717; over 20 percent for industries 3581, 3584, and 3641.

Table 8.--COPPER AND COPPER-BASE ALLOY MILL SHAPES AND CASTINGS CONSUMED BY METAL FABRICATING ESTABLISHMENTS, FOR SELECTED INDUSTRY GROUPS AND INDUSTRIES: 1953, 1952, 1951, AND 1950 (Figures in SHORT TONS. Estimates are published for industries (1) which consumed at least 1,000 tons of copper and copper-base alloys in 1953, 1952, 1951, and 1950, and (2) for which the standard error of estimate is 15 percent or less. Unpublished estimates, including those which can be derived by subtraction, may have standard errors considerably in excess of the published data. Data shown for 1952 and 1951 include both copper and copper-base alloy purchases and interplant transfers, and copper and copper-base alloys produced and consumed in the same establishment. For 1953 and 1950, the data shown exclude tonnages of copper and copper-base alloys produced and consumed in the same establishment. As a result, 1953 and 1950 data are not comparable with those for 1951 and 1952. The total quantity of copper and copper-base alloy castings produced and consumed in the same establishment in 1953 was 293,396 short tons, with a standard error of estimate of 3 percent. The total quantity of copper and copper-base alloys produced and consumed in the same establishment in 1950 was standard error of estimate of 15 percent. 205,218 short tons with a Those industries where copper and copper-base alloys produced and consumed in the same establishment in 1950 made up a substantial percent (5 percent or more) of the total copper and copper-base alloy consumption of the industry have been footnoted to indicate the approximate range of the percentage which copper and copper-base alloys produced and consumed in the same establishment bear to total copper and copper-base alloy consumption in the industry.)

ANNUAL SURVEY OF MANUFACTURES: 1953 PART II PRODUCT STATISTICS PRODUCTION AND SHIPMENTS OF SELECTED PRODUCTS FOR THE UNITED STATES: 1953 AND 1952 The Censuses of Manufactures have been the source of the most detailed commodity statistics generally available for products manufactured in the United States. 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. The commodity surveys which the Bureau of the Census has conducted for many years on. a monthly, quarterly, or annual basis obtained 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. For 1953, the Bureau of the Census conducted 68 commodity surveys which yielded detailed statistics for about 2, 300 products. Statistics for these commodities are regularly published in the Bureau of the Census "Facts for Industry" series of releases and in corresponding annual summaries, each of which cover related types of commodities. Part II of the present volume brings together in a single place the annual production and shipments statistics available from these surveys. It includes comparable figures for 1953 and 1952. An analogous summary was included in the Annual Survey of Manufactures volume for 1952, which showed figures for 1952 and 1951. These figures are generally comparable with the 1947 and 1939 commodity statistics published in the 1947 Census of Manufactures (table 6 of Volume II, Statistics by Industry; and in the Product Supplement volume). The 6, 100 individual products for which 1947 Census data were published have been grouped into approximately 1,000 product classes. Data on value of shipments of these product classes are given in the Annual Survey of Manufactures, insofar as they meet publication standards. These data are summarized in Part I, Chapter III, table 1, of the present volume. The 1953 Census commodity program included statistics for approximately 240 product classes in whole or in part, and all products in Part II have been grouped into these classes. The product-class code number is shown following each product-class name. If data are not available for every product in a product class, the word "selected" has been added after the product-class number, or the words "part of" precede this number. Totals for a product class are shown only if data for all component products are available. 140 The product classes associated with each major industry group are shown in the following table. The table is divided into 20 sections, representing 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 materials 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 separately in the "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. A complete list of the Census "Facts for Industry'' releases for the year 1953 is shown at the end of Part II. This list indicates the frequency of each release, as well as its number and name. The releases are classified on the basis of the principal types of commodities which they cover. In general, the commodity data represent complete coverage of the items for which statistics are shown. Footnotes to the table indicate the extent of the limitations of 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 as well as other users of the statistics. In addition to the Census commodity statistics, other Federal Agencies and private industrial groups collect selected commodity data. The first footnote of each section of the following table includes references to other available Federal Government sources that publish additional information on the products of that section. |
