1 dwithheld to avoid disclosing figures of individual companies.

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.

In 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 thans

(1) The percentage shoin: approximately 2 times out of 3.
(11) Tvice the percentage shown: approximately 19 times out of 20.

(111) Three times the percentage shown: almost always. 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 6.--COPPER AND COPPER-BASE ALLOY 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 1,000 tons of
copper and copper-base alloy in 1950 and 2,000 tons in 1949, and (2) for which the standard error of estimate
for the quantity figures is 15 percent or less. Unpublished estimates, including those which could be derived
by subtraction, have standard errors considerably in excess of the published data. The total quantity of cop-
per produced and consumed in the same establishments for the metal fabricating industries in 1950 was 205,218
short tons with a standard error of estimate of 15 percent, and 122,144 short tons with a standard error of
estimate of 15 percent in 1949; data for individual industries are not shown because the standard error asso-
ciated with the estimates 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 copper were collected
in 1950, 1949, and 1947. For a list of such Industries, see the 1947 Census of Manufactures, Volume 1, Chapter
Ix, table 11 and the text entitled "Metals" preceding that table.)

In 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.
