S. by States, 1939 and 1937 Source: United States Bureau of the Census (Because they account for a negligible portion of the national output, plants with annual production valued under $5,000 have been excluded since 1919.) MANUFACTURERS IN U. S. BY STATES, 1939 AND 1937-(Continued) The experience in England (1915-19 and 1940-41) has shown, according to the United States Department of Labor, that, except for short periods, an extension of the usual hours of work does not give a proportional increase in output; also, the high production level which follows with the introduction of overtime soon subsides and is followed by a production level which the worker feels he can maintain over a longer number of hours without overfatigue. Total output level may be no higher, in fact may be lower, than during the shorter workweek. The figures above, 1849-1899, cover factories, and every plant with yearly products valued at $500 or hand and neighborhood industries, and include more. Value figures for 1869 are on a gold basis. 1899 1904 1909 1914 FACTORIES, EXCLUDING HAND AND NEighborhood INDUSTRIES, 1899-1914 FACTORIES WITH PRODUCTS VALUED AT $5,000 OR MORE A YEAR, 1914-1939 Salaried persons in 1939 numbered 1,048.607 against 1,217,171 in 1937; and their salaries totaled $2,540,357,370 in 1939 and $2,716,866,216 in 1937.

In nearly every city for which data are presented by color, the differences between the 1930 and 1940 proportions for white males were smaller than the corresponding differences for nonwhite males.

In most of the cities for which the nonwhite samples were large enough to afford reliable estimates, the percentages for white females in 1940 were about the same as, or slightly larger than, those for 1930. On the other hand, the proportion of nonwhite female workers was smaller in 1940 than in 1930 in all of the cities with the exception of Richmond, where the proportion was 52.5 percent in 1930 and 56.3 percent in 1940, and Los Angeles, where the proportions were about the same. The 1940 figures are estimates based on a preliminary tabulation of a five percent cross-section of the population enumerated in each of the census enumeration districts. |
