2Excludes shipments from fluid milk plants.

3Does not include small amounts withheld in the 1947 Census tables to avoid disclosure of figures for individual companies. "Revised.

Includes knit outerwear T-shirts made in underwear mills, which were valued at $20,221,000 in 1947. "The 1947 value of shipments figures for rough lumber and for dressed lumber published in the 1947 Census of Manufactures reports, $920,452 thousand and $1,185,762 thousand, respectively, are not strictly comparable with the 1949 and 1950 estimates because (a) $213,000 thousand value of shipments for sawmills producing between 200 M and 1,000 M board feet of lumber was assumed to have been rough lumber but subsequent analysis of the reported data indicates that a considerable portion of this lumber was shipped in dressed form, and (b) value of shipments data were not collected from sawmills producing less than 200 M board feet. The small mills (less than 200 M board feet) account for approximately 5 percent of the total production of lumber.

"Less than 3 percent of this total represents shipments by establishments primarily engaged in activities classified as nonmanufacturing. 8Figure represents value of production.

Figure represents value of coal chemical materials sold or used.

10In the 1950 Annual Survey quarry tile is classified in product class 32590 "Other structural clay products". However, Facts for Industry Series M26B from which the figures for product class 32530 were obtained, includes quarry tile with floor and wall tile.

11The 1947 values for product classes 36141, 36142, 36143, and 36144 are not strictly comparable with the 1950 estimates for these product classes because the value of interplant transfers of motors and generators is excluded from the 1947 data for these specific classes of products. Transfer values are included in the 1950 figures. In 1947, the following values were reported:

1950 and 10,000 tons in 1949, and (2) for which the standard error of estimates for figures in columns A and D is 15 percent or
less. Unpublished estimates, including those which can be derived by subtraction, have standard errors considerably in excess

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 10,000 tons.

1In the 1947 Census of Manufacturers, very small consumers were not required to report their consumption of iron castings. 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. (iii) Three times the percentage shown: almost always.

Estimates for 1950 and 1949 are included

3Data on consumption of metal shapes and forms for certain 4-digit industries were not collected in 1947. in the totals of this table only for those 4-digit industries for which comparable data were collected in the three years. One of the industries thus excluded, and which consumed a substantial amount of iron castings, is industry 3599 (Machine shops). For this reason, totals for the 3-digit industry group 359 are not shown. The effect this omitted industry has on the total consumption of iron castings at the major (2-digit) industry group level, however, is believed to be insignificant.

Table 3.--CARBON STEEL MILL SHAPES AND CASTINGS CONSUMED BY METAL FABRICATING ESTABLISHMENTS, BY SELECTED INDUSTRY GROUPS AND INDUSTRIES: 1950, 1949, AND 1947

(Money figures in THOUSANDS. Estimates are published for industries (1) which consumed at least 5,000 tons of carbon steel in 1950 and 1949, and (2) for which the standard error of estimate for figures in columns A and C is 15 percent or less. Unpublished estimates, including those which can be derived by subtraction, have standard errors considerably in excess of the published data. The total quantity of carbon steel produced and consumed in the same establishments for the metal fabricating industries in 1950 was 303,758 short tons with a standard error of estimate of 2 percent; data for individual industries are not shown because the standard error of estimate exceeds 15 percent in virtually all instances. 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 in 1950, 1949, and 1947. For a list of such industries, see the 1947 Census of Manufactures, Volume I, Chapter IX, table 11 and the text entitled "Metals" preceding that table.)
