According to Israel's Central Bureau of Statistics, in 2008, of Israel's 7.3 million people, 75.6% were Jews of any background<1>. Among them, 70.3% were Sabras (Israeli-born), mostly second- or third-generation Israelis, and the rest are olim (Jewish immigrants to Israel) — 20.5% from Europe and the Americas, and 9.2% from Asia and Africa, including the Arab countries.<2>

About 35% of all Israeli Jews are recently (first or second generation) descended from European Jews, while 25% are descended from Jews who immigrated from Arab countries, Iran, Turkey and Central Asia. In addition, 45.6 thousands (0.8%) are, or are descended from Indian Jews, and 106.9 thousands (1.9%) - from Ethiopian Jews<2>.

Modern divisions

Geographic illustration of the major Jewish ethnic divisions in Afro-Eurasia c. 1490 ADHistorically, Jews have been identified into two major groups: the Ashkenazim, or "Germanics" ("Ashkenaz" meaning "Germany" in Medieval Hebrew, denoting their Central European base), and the Sephardim, or "Hispanics" ("Sefarad" meaning "Hispania" or "Iberia" in Hebrew, denoting their Spanish and Portuguese base). The Mizrahim, or "Easterners" ("Mizrach" being "East" in Hebrew), that is Middle Eastern and North African Jews, could constitute a third major group.

Smaller Jewish groups include the Georgian Jews and Mountain Jews from the Caucasus; Indian Jews including the Bene Israel, Bnei Menashe, Cochin Jews and Bene Ephraim; the Romaniotes of Greece; the ancient Italian Jewish community; the Teimanim from the Yemen and Oman; various African Jews, including most numerously the Beta Israel of Ethiopia; the Bukharan Jews of Central Asia; and Chinese Jews, most notably the Kaifeng Jews, as well as various other distinct but now extinct communities.

The divisions between all these groups are rough and their boundaries aren’t solid. The Mizrahim for example, are a heterogeneous collection of North African and Middle Eastern Jewish communities which are often as unrelated to each other as they are to any of the earlier mentioned Jewish groups. In modern usage, however, the Mizrahim are also termed Sephardi due to similar styles of liturgy, despite independent evolutions from Sephardim proper. Thus, among Mizrahim there are Iraqi Jews, Egyptian Jews, Tunisian Jews, Algerian Jews , Moroccan Jews Lebanese Jews, Kurdish Jews, Libyan Jews, Syrian Jews, and various others. The Yemenite Jews ("Teimanim") from Yemen and Oman are sometimes included, although their style of liturgy is unique and they differ in respect to the admixture found among them to that found in Mizrahim. Additionally, there is a difference between the pre-existing Middle Eastern and North African Jewish communities as distinct from the descendants of those Sephardi migrants who established themselves in the Middle East and North Africa after the expulsion of the Jews from Spain by the Catholic Monarchs in 1492, and a few years later from the expulsion decreed in Portugal.

Despite this diversity, Ashkenazi Jews represent the bulk of modern Jewry, estimated at between 70% and 80% of Jews worldwide<3><4> (and up to 90% prior to World War II and the Holocaust)<3>. As a result of their emigration from Europe during the wartime periods, Ashkenazim also represent the overwhelming majority of Jews in the New World continents and in countries previously without native Jewish communities, such as the United States, Canada, United Kingdom, Argentina, Australia, Brazil and South Africa, with Venezuela and Panama being an exception since Sefaradim compose the majority of the Jewish communities in these two countries. In France, Mizrahi immigrants from North Africa and their descendants now outnumber pre-existing European Jews. Only in Israel is the Jewish population representative of all groups, a melting pot independent of each group's proportion within the overall world Jewish population.
