Israel was established as a homeland for the Jewish people and is often referred to as a Jewish state. The country's Law of Return grants all Jews and those of Jewish ancestry the right to Israeli citizenship. Over three quarters, or 75.5%, of the population are Jews from a diversity of Jewish backgrounds. Around 4% of Israelis (300,000), ethnically defined as "others", are Russian descendants of Jewish origin or family who are not Jewish according to rabbinical law, but were eligible for Israeli citizenship under the Law of Return. Approximately 75% of Israeli Jews are born in Israel, 17% are immigrants from Europe and the Americas, and 8% are immigrants from Asia and Africa (including the Arab World). Jews from Europe and the former Soviet Union and their descendants born in Israel, including Ashkenazi Jews, constitute approximately 50% of Jewish Israelis. Jews who left or fled Arab and Muslim countries and their descendants, including both Mizrahi and Sephardi Jews, form most of the rest of the Jewish population. Jewish intermarriage rates run at over 35% and recent studies suggest that the percentage of Israelis descended from both Sephardi and Ashkenazi Jews increases by 0.5 percent every year, with over 25% of school children now originating from both communities.
