SWithheld because the standard error of estimate exceeds 15 percent. 1In the 1947 Census of Manufacturers, 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. 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. 11) Twice the percentage shown: approximately 19 times out of 20. (iii) Three times the percentage shown: almost always. Data on steel castings were collected as a single item in the 1947 Census of Manufactures. In the 1950 and 1949 Annual Surveys of Manufactures, carbon steel castings 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 totals shown in this release is minor since the consumption of steel castings is small compared to the total steel mill shapes consumed. "Figures include small quantities or values of alloy or stainless steel. (See 1947 Census of Manufactures, Volume I, Chapter IX, table 11.) "Data 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 carbon steel, are industries 3499 (Fabricated metal products, n.e.c.) and 3599 (Machine shops). For this reason, totals for the 3-digit industry groups 349 and 359 are not shown. The effect these omitted industries have on the total consumption of carbon steel at the major (2-digit) industry group level, however, is believed to be insignificant.
