Code SHIPMENTS Table 1.--VALUE OF SHIPMENTS, BY SELECTED CLASSES OF PRODUCTS, FOR THE UNITED STATES: 1951, 1950 AND 1947-Continued Α B NOTE: The product classes aggregates (shown by a 4-digit code and a dash) for 1947 are understated to the extent that 1947 shipments "not specified by kind" were omitted from the individual product class totals. (Such shipments are, however, included in the appropriate individual 1950 and 1951 product class totals.) The amount of such understatement in the 1947 totals (usually insignificant) can be determined from the "not specified by kind" shipments total in the "All industries" column of table 5 for each industry in Volume II, 1947 Census of Manufactures. n.a.

The estimates will differ from the complete totals by less than: The 1951 standard errors can also be used as an approximation of the 1950 standard errors. In most cases they slightly overstate the actual 1950 standard error. 2For some product classes the reliability of the relative values has not been determined. These are indicated by dots (...) in columns (G) and (H). 3The percentage standard errors in this column indicate the differences that can be expected between the sample estimates of the relative values (1951 value of shipments/1950 value of shipments) shown in column G, and comparable relatives based on complete coverage. The frequencies shown in footnote / also apply to this column. The absolute standard error of the amount of change in the value of shipments between 1950 and 1951 may also be determined by multiplying the 1951 value of shipments by the standard error (percent) shown in column H.) "Figures contain some duplication because of the inclusion of resales and products shipped for further processing in other plants within the industry. In 1947, such duplication amounted to about 15 percent for both the value of fresh meats and prepared meats. Such resales comprise a smaller proportion of the 1950 and 1951 values.

The small mills (less than 200 M board feet) account for approximately 5 percent of the total production of lumber. 13Revised to include values for wood storm sash and doors. (Prior to the 1951 Annual Survey these products were coded 25613.) 14Total adjusted to include a small amount of shipments of products not specified by kind. 15 Data for 1951 and 1950 include the value of mattresses and pads for infant's cribs and baskets. 1947 data exclude these mattresses had a value of $10.9 million. which 16Less than 3 percent of this total represents shipments by establishments primarily engaged in activities classified as nonmanufacturing. 17Includes data for product class code 28343. 18Includes data for product class code 28418. 19Includes data for product class code 28428. 20Figures represent value of production. 21Figures represent value of coal chemical materials sold or used. 22 Excludes parts and attachments for products classified in this class of products. 23Metal Storm Sash and Combination Screen and Storm Sash and Doors were previously classified in Industry 2561. 24Withheld for security considerations, on the advice of the Bureau of the Budget. 25 Includes parts and attachments for products classified in this class of products. 26 Includes front end attachments, buckets, grapples, slings, etc., for power cranes, draglines, and shovels, draglines, and shovels. and parts for power cranes, 27 For 1951 and 1950, the value of parts and attachments is included with the appropriate class of products. For 1947, the value of parts and attachments (except parts and attachments for power cranes, draglines, and shovels) was included with the class of products "Other construction, mining and similar machinery" which totaled $259 million in that year. Includes parts for all types of metalworking machinery (except parts, attachments, and accessories for power driven hand tools). 29Data for 1950 and 1951 are not strictly comparable with 1947 figures, since cutting tools, jigs, fixtures, etc., not reported by type, amounting to $45.0 million were reported in 1947, but were not distributed among the product classes in Industry 3543 for that year. The classification, "Not reported by type," was not used in the 1950 and 1951 surveys. Accordingly, all data reported for those years were coded in one of the specified classes of products for this industry. 3oData for 1950 and 1951 are not strictly comparable with 1947 figures, since special industry machinery, not reported by type, amounting to $25.7 million was reported in 1947, but was not distributed among the product classes in Industry 3559 for that year. The classification, "Not reported by type," was not used in the 1950 and 1951 surveys. Accordingly, all data reported for those years were coded in one of the specified classes of products for this industry. 31Data for parts are included in the 1950 and 1951 figures, but are excluded from the 1947 figure. The value of shipments types of pumps and compressors in 1947 was $78.1 million, a substantial portion of which represents parts for industrial pumps. of parts for all 32 Data for 1950 and 1951 are not strictly comparable with 1947 figures, since industrial furnaces and ovens, not reported by type, amounting to $10.7 million were reported in 1947, but were not distributed among the product classes in Industry 3567 for that year. The classification, "Not reported by type," was not used in the 1950 and 1951 surveys. Accordingly, all data reported for those years were coded in one of the specified classes of products for this industry. 33Includes parts and attachments for sewing machines (except cases and cabinets, and sewing machine needles). 34Data for 1950 and 1951 are not strictly comparable with 1947 figures since motors, generators and motor-generator sets, not specified by type, amounting to $14.1 million were reported in 1947, but were not distributed among the product classes in Industry 3614 for that year. The classification, "Not reported by type," was not used in the 1950 and 1951 surveys. Accordingly, all data reported for those years were coded in one of the specified classes of products for this industry. 35 Includes welding parts, components, and accessories for arc welding machinery, such as electrode holders, ground clamps, 36 Includes X-ray accessories and dental and industrial X-ray components and assemblies. and arc torches. 37 The current survey M45F: Truck trailer from which these product figures were obtained, includes data only for truck trailers having one or more axles with a rating of 10,000 pounds or more per axle. 38 Includes parts and attachments for all types of industrial food-products machinery. 39 'Includes parts, accessories, and attachments for all types of domestic laundry equipment. Table 1.--CARBON STEEL MILL SHAPES AND CASTINGS CONSUMED BY METAL FABRICATING ESTABLISHMENTS, FOR SELECTED INDUSTRY GROUPS (Dollar figures in THOUSANDS. Estimates are published for industries (1) which consumed at least 5,000 tons of carbon steel in 1951, 1950, and 1949, and (2) for which the standard error of estimate for the quantity figures 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 1951 by specific 4-digit industry include both carbon steel purchases and interplant transfers, and carbon steel produced and consumed in the same establishment; 1950 and 1949 data presented by specific 4-digit industry exclude tonnages of carbon steel produced and consumed in the same establishment. The total quantity of carbon steel produced and consumed in the same establishment in 1950 was 303,758 short tons with a standard error of estimate of 2 percent; in 1949, the total quantity of carbon steel produced and consumed in the same establishments, 276,070 short tons with a standard error of estimate of 2 percent. Those industries were carbon steel produced and consumed in the same establishment during 1949 and 1950 made up a substantial percent (5 percent or more) of the total carbon steel consumption of the industry have been footnoted for 1951 to indicate the approximate range of the percentage which carbon steel produced and consumed in the same establishment bears to total carbon steel consumption in the industry. Industry group totals (2-digit and 3-digit) include only the estimates for those industries for which data on consumption of carbon steel were collected for all 4 years. For a list of such industries, see the 1947 Census of Manufactures, Volume I, Chapter IX, table 11 and the text intitled "Metals" preceding that table. Also see footnote 7 to this table.) 95 Table 1.--CARBON STEEL MILL SHAPES AND CASTINGS CONSUMED BY METAL FABRICATING ESTABLISHMENTS, FOR SELECTED INDUSTRY GROUPS Table 1.--CARBON STEEL MILL SHAPES AND CASTINGS CONSUMED BY METAL FABRICATING ESTABLISHMENTS, FOR SELECTED INDUSTRY GROUPS withheld because the standard error of the quantity estimate exceeds 15 percent or because the quantity consumed was less than 5,000 tons. 1Compiled from the NPAF-1 and NPAF-103 surveys. 2In the 1947 Census of Manufactures, very small consumers were not required to report their consumption of carbon steel. The understatement of 1947 data for this reason is estimated at less than 2 percent on an over-all basis. 3The 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. The standard errors for the 1949 estimates of quantity and cost (columns D and E) may be used as a general guide to the relationship between the standard errors of the 1950 estimates. For the other 3 years, carbon steel castings *Data on steel castings were collected as a single item in the 1947 Census of Manufactures. were collected as a combined item with carbon steel mill shapes, while alloy and stainless steel castings were collected as a combined figure with alloy and stainless steel mill shapes. In this table, the 1947 data for steel castings have been combined with carbon steel mill shapes, since over 75 percent of the 1947 steel castings shipped were carbon steel. The degree of noncomparability for the total shown in this release is minor since the consumption of steel castings is small compared to the total steel mill shapes consumed. "Revised. "Figures include small quantities or values of alloy or stainless steel. See 1947 Census of Manufactures, Volume I, Chapter IX, table 11. 7In the NPAF-1 and NPAF-103 surveys from which the 1951 data were obtained, nails, spikes, etc., were considered mill shapes and therefore carbon steel consumed in the production of these products was not reported during 1951. Consumption of nails, spikes, etc., by establishments classified in the metalworking industries, however, was reported by the industries consuming these products. Since the major portion of nails, spikes, etc., are consumed in industries outside the metalworking area, such as construction and normanufacturing activities, total carbon steel consumption in 1951 is understated. 8Data on consumption of metal shapes and forms for certain 4-digit industries were not collected in 1947. Since there was no base total from which to prepare estimated data, these 4-digit industries are not included in this table. Also, separate data for certain 3-digit industries are not published because of such excluded industries. Industries for which data were not collected in 1947, and which are excluded from this table are 3465-8, 3492, 3496, 3497, 3499, 3592, 3599, 3612, 3651, 3662, 3663, 3691, 3692, 3693, 3699, 3723, and 3799. "The approximate range of the percentage which carbon steel produced and consumed in the same establishment bears to total carbon steel consumption in 1951 is estimated for the following industries where this range is 5 percent or more: 5 percent but not more than 10 percent for industries 3591 and 3741; over 10 percent but not more than 20 percent for industries 3521 and 3542. 1°Withheld for security reasons, on the advice of the Bureau of the Budget. 11Sampling error not available due to method of computing 1951 figure. |
