Between 1924 and 1929, 82,000 Jews arrived, many as a result of increasing Anti-Semitism in Poland and throughout Europe. The vast majority of Jewish immigrants arrived from Europe mostly from Poland, the Soviet Union, Romania, and Lithuania, but about 12% came from Asia, mostly Yemen and Iraq. The immigration quotas of the United States kept Jews out. This group contained many middle-class families that moved to the growing towns, establishing small businesses, and light industry. Of these approximately 23,000 left the country.
