-By 1910 arrivals from Mexico were beginning to outnumber arrivals from Ireland and large numbers of Japanese had moved to the West Coast and Hawaii. Approximately 2/3 of the newcomers were males, especially after 1900 and about 2/3 were between the ages of 15 and 39. Not all groups were equally educated, but almost 3/4 of the immigrants could read and write at lest in their native languages. -The reason for immigration in this period is quite clear. Land remained plentiful, and fairly cheap. Jobs were abundant, and labor was scarce and relatively dear. A decline in the birthrate as well as an increase in industry and urbanization reinforced this situation. • Jews came for religious freedom
• Italians and Asians came for Work
• Russians came to escape persecution
• America had jobs
• America had religious freedom
• America was hyped up in many countries as "Land of Opportunity"

Jews: Many Jewish people came to the US at this time. In the 1880s Jews were being killed all over eastern Europe in bloody masacres called „pogroms“. Tsar Nicholas I created the Pale of Jewish Settlement in April 1835 -a limited geographical area where Jews were mandated to live. The Pale included Lithuania, Poland, the south-western provinces, and White Russia. Within the Pale, Jews were banned from most rural areas and some cities; they were prohibited from building synagogues near churches and using Hebrew in official documents; barred from agriculture, they earned a living as petty traders, middlemen, shopkeepers, peddlers, and artisans. The official view was that Jews were a parasitic element in the Russian Empire who lived off the hard earned wages of the narod [people].
Jews in Europe were seen by many as alien to the nation or the. The peasants in Russia viewed Jews as aliens; their religion, language, food, clothing, and manners were all different, strange, and mysterious—even the government discriminated against them. Russian bureaucrats believed that the teachings of Judaism itself lead Jews into unproductive, parasitical, and exploitative commercial activities. During the decade before the pogroms of 1881, a growing atmosphere of crisis surrounded the Jewish Question in Russia. Prompted by an increasingly militant Judeophobe press, Russian statesmen held their old prejudiced view of the Jews as a serious economic and social problem.
The assassination of Tsar Alexander II in 1881 threw the Russian government into chaos and directly preceded the first major outbreak of pogroms. A wave of pogroms spread throughout the southwestern regions, totaling 200 in 1881.
