From The Great Departure: Mass Migration from Eastern Europe and the Making of the Free World, by Tara Zahra (Norton, 2016), Kindle Loc. 388-410:
In part, the preoccupation with maintaining population in imperial Austria was linked to the explosive growth of popular nationalist movements at the end of the nineteenth century. In the nationalist battle for supremacy, numbers mattered. Beginning in 1880, when citizens were first asked about their “language of daily use,” the imperial census escalated into a high-stakes campaign for citizens’ allegiances, as the number of Czech-speakers, German-speakers, Polish-speakers, or Ruthene-speakers counted came to be seen as a measure of national strength. Increasingly, numbers determined how state resources were allocated, where schools were built, and in which languages children could be educated.
It follows logically that nationalists would mobilize to prevent the emigration of members of their own national community and encourage the exodus of national rivals. The Hungarian government, which operated somewhat like a nation-state within the Dual Monarchy (sharing only a common foreign policy and military with Austria), did just that. As of 1904, two-thirds of the emigrants leaving the Hungarian half of the monarchy were not native Hungarian-speakers. A secret memorandum from the Hungarian undersecretary of state to the Hungarian prime minister explained, “For the institution of national statehood it is absolutely necessary that the ruling race . . . become the majority of the population. . . . Providence . . . has granted another population factor which has significantly raised the proportion of the Hungarian element at the expense of the nationalities. . . . This important new factor is the mass emigration of the non-Hungarian population.”
In Russia as well, imperial authorities began to encourage Jewish emigration in the 1890s, while restricting the emigration of nationally “desirable” citizens. The Russian government allowed the Jewish Colonization Association (JCA) to set up branches across the empire beginning in 1892, effectively legalizing Jewish emigration, even though emigration remained illegal for non-Jewish Russians. The JCA had established four hundred offices throughout Russia by 1910, providing migrants with information about opportunities to emigrate and assisting with the burdensome paperwork.
In Vienna, by contrast, imperial authorities officially mourned the loss of all the kaiser’s subjects equally. In 1905, out of 111,990 emigrants from Austria to the United States, 50,785 (45 percent) were Polish-speakers, 14,473 (14 percent) spoke Ruthene (a language later known as Ukrainian), and 11,757 (10 percent) were Czech-speakers. In contrast to their proportion in the emigration from imperial Russia, where anti-Semitic persecution was much more severe, Jews were not heavily overrepresented among emigrants from the Dual Monarchy. Out of a total of 275,693 emigrants from Austria-Hungary in 1905, for example, 17,352 emigrants (6 percent) were Jewish, only slightly more than the percentage of Jews in the total population in 1900 (4.7 percent in Austria, 5 percent in Hungary).
