Table 4.--COPPER AND COPPER-BASE ALLOY MILL SHAPES AND CASTINGS CONSUMED BY METAL FABRICATING ESTABLISHMENTS, FOR SELECTED swithheld because the standard error of the quantity estimate exceeds 15 percent or because the quantity consumed was less than 1,000 tons for 1951 and 1950, or 2,000 tons for 1949. 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 copper and copper-base alloys. The understatement of 1947 data for this reason is estimated at less than 2 percent on an over-all basis. 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 canvas 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. "Revised. "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 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 3494, 3542, 3551, 3571, 3611, 3664, and 3741; over 10 percent but not more than 20 percent for industries 3429, 3552, and 3593; over 20 percent for industries 3431, 3519, 3531, 3561, 3566, 3591, 3731, and 3742. "Data 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 3391, 3465-8, 3492, 3496, 3497, 3499, 3592, 3599, 3612, 3651, 3662, 3663, 3691, 3692, 3693, 3699, 3723, and 3799.

Swithheld because the estimate did not meet publication standards, either on the basis of the associated standard error of estimate or on the basis of consistency review. 1The 1950 cost estimates and their standard errors are revisions of those published in the volume, Annual Survey of Manufactures: 1949 and 1950. Detailed 1950 figures are presented by selected 3- and 4-digit industries and by 2-digit industry group within State in the publication, MAS-50-9 Fuels Consumed and Electric Energy Purchased: 1950 and 1947. 2In the 1947 Census of Manufactures, smaller establishments submitting "short" form reports were not requested to supply data on fuels and electric energy. The resulting understatement is negligible for most major groups. For an indication of the extent of this understatement see Chapter VIII of Volume I, "General Summary," Census of Manufactures, 1947. 3The percentage standard errors shown in this column indicate the differences that can be expected between the estimates and comparable complete canvass totals, because of sampling fluctuations. The estimates will differ from the complete totals by less than: 1) The percentage shown: approximately 2 times out of 3. No such computations have been made for 1951. However, the standard errors of the 1950 estimates would be indicative of the 1951 errors. Includes all purchased fuel used for power and heat, such as anthracite and bituminous coal, natural and manufactured gas, fuel oil, liquefied petroleum gas, gasoline, and wood. 5The 1951 and 1950 figures for Major Group 24 are not strictly comparable to those for 1947 since Industry 2411 - Logging Camps and Logging Contractors was excluded from the 1947 Census of Manufactures, but included in the 1951 and 1950 Annual Surveys of Manufactures. Table 6.--VALUE OF MANUFACTURERS' INVENTORIES FOR MAJOR (DOLLAR FIGURES IN THOUSANDS.

Some of the estimates have been revised and therefore differ from previously published data. The In the 1947 Census of Manufactures, smaller establishments submitting "short" form reports were not requested to include inventory data. The understatement of value of inventories resulting from this is negligible. For a measure of the degree of understatement see Chapter V of Volume I, "General Summary," Census of Manufactures, 1947. METALS, FUELS, AND INVENTORIES INDUSTRY GROUPS END OF YEAR: 1951, 1950, 1949, AND 1947 their inventories at both the beginning and end of the year. In the annual surveys all establishments are required to report inventories except establishments reporting on "short" forms in all industries.

The estimates will differ from the complete totals by less than: (1) The percentage shown: approximately 2 times out of 3.
