Data for 1947-1951 include all establishments employing one or more persons at any time during the year; for 1921-1939, those with products valued at $5,000 or more; and for 1849-1919, those having products valued at $500 or more.

The figures for 1939-1951 include data for employees at manufacturing establishments who were engaged in distribution and in construction work. The extent to which data for such employees were included in the figures for earlier years is not known. 2The 1951, 1950, and 1949 "Average number of employees" is based on reported employment totals for the pay roll periods nearest the 15th of March, May, August, and November. For 1947, the number of "All employees" represents the average of 12 monthly figures; for 1939 and earlier years, it represents the sum of the average number of production workers for the year and the number of nonproduction workers reported for one pay roll period (usually in October). See 1947 Census of Manufactures volumes, GENERAL EXPLANATIONS - Monthly and average employment. BValue of products less cost of materials, supplies, fuel, electric energy, and contract work. For 1849 - 1933, cost of contract work was not subtracted from value of products in calculating value added by manufacture. See 1947 Census of Manufactures volumes, GENERAL EXPLANATIONS - Value added by manufacture. “Data for 1951, 1950, and 1949 are estimates based on establishments' reports received in the Annual Survey of Manufactures. The survey estimates, of course, vary from the totals that would have been obtained from a complete canvass as conducted in prior years; the relative magnitude of this sampling variation 18 indicated in Chapter I, table 2, in the column captioned "Standard error of estimate." 5The number of establishments classified as engaged primarily in manufacturing activities is estimated at 262,000 for 1951 and 260,000 for 1950. (These estimates have a standard error of 2 percent.) Because of sampling variation, and some differences in definitions, scope, etc., these totals differ to some extent from the establishment counts presented in the joint Census-BOASI publication County Business Patterns, The totals shown for 1951, 1950, and 1949 include employees separately reported at central administrative offices and auxiliary establishments. ?To maintain comparability with 1951 and 1949 employment estimates, the employment total for 1950 has been ad justed to include employment at plants not in production at any time during the year. Employment at these plants is estimated at 82,000 during 1950. The extent to which data for such employees were included in the figures prior to 1949 is not known. 8The figures for 1939, but not for earlier years, have been revised on the basis of retabulation of the returns to exclude data for establishments classified as manufacturing in 1939 and prior years but classified as nonmanufacturing beginning with 1947. Value added by manufacture for 1939, prior to revision and on a basis comparable with 1937 and previous years, was $24.7 billion. See 1947 Census of Manufactures volumes, GENERAL EXPLANATIONS - Statistics for 1939 and earlier years. Not revised to exclude data for establishments classified as manufacturing in 1939 and prior years but classified as non-manufacturing beginning with 1947 (See footnote 8). 10 The 1939 figures for "All employees" were revised on the basis of estimates rather than by retabulation of the 1939 reports. The estimates were made in the following manner: for number of employees, by multiplying the retabulated figure for number of production workers by the ratio of all employees to production workers computed from the unrevised 1939 statistics; for salaries and wages, by multiplying the retabulated wage figure by the ratio for salaries and wages also derived from the unrevised 1939 statistics. 11Not including data for salaried officers of corporations and their salaries and, therefore, not strictly comparable with figures for other years. 1 2 Reduced to gold basis. . 13 Table 2.--GENERAL STATISTICS, BY INDUSTRY GROUPS: 1951, 1950, 1949 AND 1947 (Dollar figures and man-hours are in THOUSANDS.

"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 ma jor industry group, especially in Industry 2411. The sample design for the 1951 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, "Ordnance and accessories." Government owned and operated establishments are excluded from the annual survey. 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 administrative and auxiliary employment and pay roll figures for 1950 were also used for 1951, as 1951 OASI program data were not available for this publication. The approximated annual total pay roll figure shown in column B was derived by multiplying by 4 the first quar er taxable pay roll figures listed in the joint Census-BOASI publication, County Business Patterns, First Quarter 1950. To maintain comparability with 1951 and 1949 employment estimates, the "all industries" and 2-digit employment totals for 1950 have been ad justed to include employment at plants not in production at any time during the year. Employment at these plants is estimated at 82,000 during 1950. In addition, the 1950 estimates for a few industry groups have been revised for other reasons and, therefore, differ from previously published data. 8 The totals shown for 1947 do not include employment at central administrative offices and auxiliary units. |
