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. Retention of Israel's population since 1948 is about even or greater, when compared to other countries with mass immigration. Jewish emigration from Israel (called ''yerida'' in Hebrew), primarily to the United States and Canada, is described by demographers as modest, but is often cited by Israeli government ministries as a major threat to Israel's future.
