The phrase "demographic threat" (or "demographic bomb") is used within the Israeli political sphere to describe the growth of Israel's Arab citizenry as constituting a threat to its maintenance of its status as a Jewish state with a Jewish demographic majority. In the northern part of Israel the percentage of the population that is Jewish is declining. The increasing population of Arabs within Israel, and the majority status they hold in two major geographic regions – the Galilee and the Triangle – has become a growing point of open political contention in recent years. Among Arabs, Muslims have the highest birth rate, followed by Druze, and then Christians.
