In making the estimates of the average number employed in New

aThe above estimates were computed, by methods described in the accompanying text, from the U.S.
Census of Manufactures’ statistics of numbers employed in New York factories for the years 1904, 1909
1914, 1919, and 1921, with interpolations for the intervening years computed from data on unemployment
among trade union members for the years 1905 to 1913, and from data on employment in representative
factories from 1915 to 1922, published by the New York State Department of Labor.
1908 and 1910-1913, inclusive, upon the basis of the trade union
statistics of unemployment; and for the subsequent years upon the
index of factory employment published by the New York State
Department of Labor.
In utilizing the trade union figures, an index of unemployment
in the factory trades, weighted by the numbers in each trade, was
See Table 17.
