Table 5.--CARBON STEEL MILL SHAPES AND CASTINGS CONSUMED BY METAL FABRICATING ESTABLISHMENTS, FOR SELECTED INDUSTRY GROUPS AND INDUSTRIES: 1953, 1952, 1951, AND 1950 (Figures in SHORT TONS. Estimates are published for industries (1) which consumed at least 5,000 tons of carbon steel in 1953, 1952, 1951, and 1950, and (2) for which the standard error of estimate 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 Unpublished estimates, including those which can be derived by subtraction, may have standard errors considerably in excess of the published data.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 on steel castings were collected as a single item in 1953 and were included with data for carbon steel, whereas, for 1950, 1951, and 1952 alloy and stainless steel castings were collected as a combined item with alloy and stainless steel mill shapes. To this extent, data for 1953 are not comparable with those for 1950, 1951, and 1952.

Data shown for 1952 and 1951 include both carbon steel purchases and interplant transfers and carbon steel produced and consumed in the same establishment. For 1953 and 1950, the data shown exclude tommages of carbon steel produced and consumed in the same establishment.

The total quantity of steel castings (including carbon, alloy and stainless) produced and consumed in the same establishment in 1953 was 973,670 short tons, with a standard error of estimate of 1 percent.

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. Those industries where carbon steel produced and consumed in the same establishment in 1950 made up a substantial percent (5 percent or more) of the total carbon steel consumption of the industry have been footnoted 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.)

NOTE: In addition to the industries for which data are presented in this table, statistics were also collected on carbon steel consumed in the selected furniture and fixtures industries. These data which met the standards for publication are as follows: Total carbon steel consumed in Industry 2514, "Metal Household Furniture," 191,027 tons with a standard error of estimate of 8 percent; Industry 2515, "Mattresses and Bedsprings," 107,213 tons, with a standard error of estimate of 6 percent; Industry 2522, "Metal Office Furniture," 119,249 tons with a standard error of estimate of 8 percent; and Industry 2541, "Metal Fixtures," 159,595 tons with a standard error of estimate of 13 percent.

SWithheld because the standard error of the quantity estimate exceeds 15 percent or because the quantity consumed was less than 5,000 tons. 1Data on steel castings (carbon, alloy, and stainless) were collected as a single item in 1953 and included with figures for carbon steel. For 1950, 1951, and 1952 carbon steel castings were included with carbon steel mill shapes and forms, and alloy and stainless steel castings included with alloy for stainless mill shapes and forms. For 1953, the approximate range of the percentage which alloy and stainless steel castings bear to the total carbon steel mill shapes and castings is estimated at between 5 and 10 percent for industries 3531 and 3532. For all other industries in this table, the proportion is less than 5 percent.

"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 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. (111) Three times the percentage shown: almost always.

Standard errors of estimates are not available for 1952 data. "Revised.

"In the NPAF-1 and NPAF-103 surveys from which the 1952 and 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. 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 matalworking area, such as construction and normanufacturing activities, total carbon steel consumption is understated.

Data for 1951 and 1952 include the metals produced and consumed in the same establishment, whereas such metals are excluded for 1950 and 1953. The degree to which the 1951 and 1952 data are not comparable with 1950 and 1953 data can be estimated through the following ratios which are based on the 1950 data. The range is less than 5 percent except as follows: 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.

(Figures in SHORT TONS. Estimates are published for industries (1) which consumed at least 2,500 tons of alloy and stainless steel in 1953, 1952, 1951, and 1950, and (2) for which the standard error of estimate 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 on steel castings were collected as a single item in 1953, and will be included with data for carbon steel, whereas, for 1950, 1951, and 1952, alloy and stainless steel castings were collected as a combined item with alloy and stainless steel mill shapes.

Data shown for 1952 and 1951 include both alloy and stainless purchases and interplant transfers for alloy and stainless steel mill shapes produced and consumed in the same establishment. For 1953 and 1950, the data shown exclude tonnages of alloy and stainless steel produced and consumed in the same establishment. However, the quantities of alloy and stainless steel produced and consumed in the same establishment considered negligible.

Table 7.-ALUMINUM MILL SHAPES AND CASTINGS CONSUMED BY METAL FABRICATING ESTABLISHMENTS,

FOR SELECTED INDUSTRY GROUPS AND INDUSTRIES: 1953, 1952, 1951, AND 1950

Estimates are published for industries (1) which consumed at least 1,000 tons of aluminum in 1953, 1952, 1951, and 1950 and (2) for which the standard error of estimate 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 1952 and 1951 include both aluminum purchases and interplant transfers, and aluminum produced and consumed in the same establishment. For 1953 and 1950, the data shown exclude tonnages of aluminum produced and consumed in the same establishment. As a result, 1953 and 1950 data are not comparable with those for 1951 and 1952.

The total quantity of aluminum castings produced and consumed in the same establishment in 1953 was 105,208 short tons, with a standard error of estimate of 3 percent.

The total quantity of aluminum produced and consumed in the same establishment in 1950 was 43,431 short tons with a standard error of estimate of 3 percent.

Those industries where aluminum produced and consumed in the same establishment in 1950 made up a substantial percent (5 percent or more) of the total aluminum consumption of the industry have been footnoted to indicate the approximate range of the percentage which aluminum produced and consumed in the same establishment bears to total aluminum consumption in the industry.)
