It is documented that immigration provided the US economy with a heavy % of M's between the ages of 14 & 44. Some estimates of the quantitative impact of the foreign-born LF on US commodity production over 1869-1929 are undertaken, utilizing estimates of per capita commodity output in the absence of foreign-born labor. Estimates of employment in the commodity producing sectors of agri, mfg, mining, & construction for the total LF & for foreign born labor were made; then a commodity output series was estimated, by sector, for 1869-1929. Average labor productivity for each commodity producing sector was constructed for the total LF. Finally, the product of average labor productivity of the total LF & immigrant employment by sector was taken to yield estimates of commodity output produced by the foreign born LF. Data show that at a relative early date mfg became the primary occup of foreign born labor, while the share of immigrants in agriculture remained low. It appears that the nation grew increasingly dependent on commodity production by foreign born labor until 1909. At that time it is estimated that 13.9% of per capita commodity production would have been lost in the absence of a foreign born LF. After 1914 there was a sharp decrease in the entry of new immigrants. This trend continued until 1930, after which time immigration fell to inconsequential levels. The shift away from dependence on commodity production by foreign born labor after 1909 reflects these changes in migration movements. 4 Tables. M. Maxfield.
