Table 5.--ALUMINUM MILL SHAPES AND CASTINGS CONSUMED BY METAL FABRICATING ESTABLISHMENTS, BY SELECTED INDUSTRY GROUPS AND INDUSTRIES: 1950, 1949, AND 1947--Continued SFor 1950, withheld because the standard error of the quantity estimate exceeds 15 percent; for 1949, withheld because the standard error of the quantity estimate exceeds 15 percent or because the quantity consumed was less than 2,000 tons. 1In the 1947 Census of Manufacturers, very small consumers were not required to report their consumption of aluminum. The understatement of 1947 data for this reason is estimated at less than 2 percent on an over-all basis. 2The 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. (ii) Twice the percentage shown: approximately 19 times out of 20. 3Data on consumption of metal shapes and forms for certain 4-digit industries were not collected in 1947. Estimates for 1950 and 1949 are included in the totals of this table only for those 4-digit industries for which comparable data were collected in the three years. Among the industries thus excluded, and which consumed a substantial amount of aluminum, are industries 3497 (Metal foil), 3499 (Fabricated metal products, n.e.c.) and 3599 (Machine shops). For this reason, totals for 3-digit groups 349 and 359 are not shown. The effect these omitted industries have on the total consumption of aluminum at the major (2-digit) industry group level, however, is believed to be insignificant. "Withheld for security considerations, on advice of the Bureau of the Budget.

Table 7.--COST OF FUELS CONSUMED AND PURCHASED ELECTRIC ENERGY FOR MAJOR INDUSTRY GROUPS: 1950 AND 1947 1In 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 a measure of the degree of understatement see Chapter VIII of Volume I, "General Summary", Census of Manufactures, 1947. 2Includes 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. 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.
