Between 1880 and 1910 the South African Jewish community grows from 4,000 to 40,000; it is predominantly comprised of Jews fleeing from pogroms and discrimination in Eastern Europe. In 1898 the South African Zionist Federation unifies several previously established Zionist/Jewish organizations. At its high point in the 1970s, the South African Jewish community reaches 120,000. However, beginning in the early 1980s, as a result of economic difficulties, South Africa loses some 1,500 Jews every year, mainly to Israel and the US.
