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.
1In the 1947 Census of Manufactures, smaller establishments submitting "short" form reports were not requested to include data on capital expenditures. The resulting understatement is negligible. For a measure of the degree of understatement, see Chapter VI of Volume I, "General Summary", Census of Manufactures, 1947.
2 The 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.
3This major group was not fully represented in the sample for 1950 and 1949. The sample design for the 1951 Annual Survey of Manufactures was revised to correct this undercoverage. Capital expenditures estimates for 1950 and 1949, therefore, are understated by approximately 1 to 10 percent for this group. The corresponding understatment in the "All industries" total line is less than 0.5 percent.
4Includes privately owned and/or operated establishments classified in Industry Group 19, "Ordnance and accessories". Government owned and operated establishments are excluded from the Annual Survey.

(Value added figures are in THOUSANDS.) Industries (4-digit) for which data are shown were selected, after review for consistency with other "Value added by manufacture." With few exceptions, the industries shown have standard errors of 15 percent or less for these entries. Totals for the individual industries. Data for any size class which cannot be shown without disclosing information for individual companies have been underlined. As a result, whenever size-class figures for individual industries (4-digit) are underlined or the symbol (d) has been substituted, industry group figures will not add to the "All industries" totals, for those size-classes in which underlined figures for the (d) symbols errors considerably in excess of 15 percent.
Census series and related data, on the basis of the standard error of estimates associated with the figures in column A for "All employees" are shown for all major (2-digit) groups; such totals include estimates for all the component industries whether or not separate data are shown combined with figures for adjacent size classes. A (d) appears in the column where the figure has been omitted, and the combined figure is the figures for the individual industries will not add to the major industry group (2-digit) total shown for that size class. Similarly, ma jor appear for one or more major industry groups. Unpublished estimates, including those which can be derived by subtraction,
may have standard
