The relative stability of an immigration may be determined by contrasting the departure of the aliens composing the immigration with the arriving immigrants of this group for the same period. From 1908 to 1912, 33,315 Jews left the United States--an average annual emigration of 6,660 Jews. This is a strikingly low number, especially when compared with the large Jewish immigration for the same period, which numbered 417,016, and averaged annually 83,400 Jewish immigrants. Thus, for every hundred Jews admitted, only eight Jews left the country. This average proportion was largely exceeded only in 1909, not, however, because of any great increase in the absolute numbers of the Jewish emigrants, but because of the great fall in the number of Jewish immigrants of this year. The part that is taken by the Jewish emigrants in the total emigration is insignificant and is in striking contrast with the great part taken by the Jewish immigrants in the total immigration.[110] From 1908 to 1912, the Jewish immigrants constituted 9.7 per cent of the total immigrants. In the same period, the Jewish emigrants constituted only 2.3 per cent of the total emigrants. Moreover, while the proportion that the Jewish immigrants constituted of the total immigrants exhibited a considerable and significant variation, fluctuating from 7.7 per cent to 13.2 per cent, the proportion the Jewish emigrants constituted of the total emigrants remained around 2 per cent and showed practically no variation. Relatively both to the number of Jewish immigrants and of total emigrants, therefore, the number of the Jewish emigrants is exceedingly small and practically negligible. How great the relative stability of the Jewish immigration is may be seen when its return movement is compared with that of the total immigration and of other peoples conspicuous in the immigration to the United States.[111] Whereas, from 1908 to 1910, for every hundred admitted in the total immigration, thirty-two departed--the outward movement thus approximating one-third of the inward--in the case of the Jewish immigration, only eight departed, an outward movement only one-quarter as large, relatively, as the total. This was the smallest outward movement, relatively to the inward, of any immigrant people, except the Irish, whose outward movement was 6 per cent of the inward. Relatively to the inward movement, the Jews had an outward movement one-seventh as large as the South Italians, almost one-fourth as large as the Poles, and less than one-half as large as the Germans.
