Compiled from the NPAF-1 and NPAF-103 surveys.

2 In the 1947 Census of Manufactures, very small consumers were not required to report their consumption of copper and copper-base alloys. The understatement of 1947 data for this reason is estimated at less than 2 percent on an over-all basis.

3The 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 canvas 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.
(11) Twice the percentage shown: approximately 19 times out of 20.

(iii) Three times the percentage shown: almost always. The standard errors for the 1949 estimates of quantity and cost (columns D and E) may be used as a general guide to the relationship between the standard errors of the 1950 estimates.

"Revised.

5The approximate range of the percentage which copper and copper-base alloys produced and consumed in the same establishment bear to total copper and copper-base alloy consumption in 1951 is estimated for the following industries where this range is 5 percent or more: 5 percent but not more than 10 percent for industries 3494, 3542, 3551, 3571, 3611, 3664, and 3741; over 10 percent but not more than 20 percent for industries 3429, 3552, and 3593; over 20 percent for industries 3431, 3519, 3531, 3561, 3566, 3591, 3731, and 3742.

Data on consumption of metal shapes and forms for certain 4-digit Industries were not collected in 1947. Since there was no base total from which to prepare estimated data, these 4-digit industries are not included in this table. Also, separate data for certain 3-digit industries are not published because of such excluded industries, Industries for which data were not collected in 1947, and which are excluded from this table are 3391, 3465-8, 3492, 3496, 3497, 3499, 3592, 3599, 3612, 3651, 3662, 3663, 3691, 3692, 3693, 3699, 3723, and 3799.

71947 data are understated by approximately 13,000 tons.

withheld because the estimate did not meet publication standards, either on the basis of the associated standard error of estimate or on the basis of consistency review.

The 1950 cost estimates and their standard errors are revisions of those published in the volume, Annual Survey of Manufactures: 1949 and 1950. Detailed 1950 figures are presented by selected 3- and 4-digit industries and by 2-digit industry group within State in the publication, MAS-50-9 Fuels Consumed and Electric Energy Purchased: 1950 and 1947.

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 most major groups. For an indication of the extent of this understatement see Chapter VIII of Volume I, "General Summary," Census of Manufactures, 1947.

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. The estimates will differ from the complete totals by less than:

i) 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. No such computations have been made for 1951. However, the standard errors of the 1950 estimates would be indicative of the 1951 errors,

5The 1951 and 1950 figures for Major Group 24 are not strictly comparable to those for 1947 since Industry 2411 - Logging Camps and Logging Contractors was excluded from the 1947 Census of Manufactures, but included in the 1951 and 1950 Anmal Surveys of Manufactures.

Ithe estimates for the end of year 1950 are the tabulated "Beginning of Year" inventory figures reported in the 1951 Annual Survey. The survey sample design was revised for the 1951 Annual Survey; therefore, the data collected in the 1951 survey has been substituted for the published year-end 1950 estimates as shown in the volume "Annual Survey of Manufactures: 1949 and 1950."

2 End of year 1949 shown in this table, are the "Beginning of year 1950" figures as shown in the Annual Survey of Manufactures: 1949 and 1950. Some of the estimates have been revised and therefore differ from previously published data.

In the 1947 Census of Manufactures, smaller establishments submitting "short" form reports were not requested to include inventory data. The understatement of value of inventories resulting from this is negligible. For a measure of the degree of understatement see Chapter V of Volume I, "General Summary," Census of Manufactures, 1947.
