with business conditions. The depression periods of 1907 to 1908, 
1911, 1913 to 1914, 1919, and 1921 to 1922, all show a net emigration, 
preceded, except in 1919, by a relatively large net immigration. 
The seasonal movement is not eliminated from this chart and, 
consequently, some of the lower points toward the end of each year 
are largely due to the normal coincidence of low immigration and 
high emigration in the late fall. 
Before endeavoring to make a more refined analysis of the relation 
of net immigration to employment conditions, let us note briefly the 
characteristics of the cyclical fluctuations in monthly male emigra- 
tion in the few years prior to the war for which such data are 
available. 
Male Emigration: 1910-1914. 
The cyclical fluctuations in emigration are the inverse of the 
cyclical fluctuations in immigration. When industry booms, im- 
migration increases and emigration decreases; when industry is 
dull, immigration declines and emigration increases. This inverse 
correlation of the inflow and outflow of aliens may be illustrated 
by comparing the monthly data in Chart 19 for male immigrants, 
male emigrants, and pig iron production, all three series being ad- 
justed so as to eliminate the typical influence of seasonal factors.
