Table 2.--GENERAL STATISTICS, BY INDUSTRY GROUPS: 1953, 1952, 1951, 1950, 1949, AND 1947--Continued All employees Number (average 1The 1949 thru 1953 "Average number of employees" is based on reported employment totals for the payroll periods ended nearest the 15th of March, May, August, and November. For 1947, an average based on the mid-month employment for 12 months was used. Value of products shipped less cost of materials, supplies, fuel, electric energy, and contract work. 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: (i) The percentage shown: approximately 2 times out of 3. (ii) Twice the percentage shown: approximately 19 times out of 20. "The logging industry (Industry 2411) was excluded for the 1947 Census of Manufactures, but included in the Annual Surveys of Manufactures. There was also some undercoverage in the 1950 and 1949 sample for this major industry group, especially in Industry 2411. The sample design for the later Annual Survey of Manufactures was revised to correct the undercoverage in this industry. "Includes privately owned and/or operated establishments classified in Industry Group 19, "Orndance and accessories." operated establishments are excluded from the annual survey. Government owned and "Administrative office and auxiliary unit employment is based on the number of employees reported as of Mid-March under the Old-Age and Survivors Insurance program. The figures shown for the current years are based on 1953 data whereas the 1952 figures represent administrative and auxiliary employment and payrolls for 1951, as 1952 OASI program data were not available in time for this publication. Similarly, when the 1951, 1950, and 1949 estimates in this table were originally published, it was necessary to use data for the previous year in each case, for this employment category. The approximated annual total payroll figure was derived by multiplying by 4 the first quarter taxable payroll figures listed in the joint Census-BOASI publication, County Business Patterns. The figures shown for administrative office and auxiliary units do not represent a separate industry but rather a balancing total for all manufacturing industries. "The totals shown for 1947 do not include employment and payrolls at central administrative offices and auxiliary units.
