A January 2006 study rejects the "demographic time bomb" threat based on statistical data that shows Jewish births have increased while Arab births have begun to drop. The study noted shortcomings in earlier demographic predictions (for example, in the 1960s, predictions suggested that Arabs would be the majority in 1990). The study also demonstrated that Christian Arab and Druze birth rates were actually below those of Jewish birth rates in Israel. The study used data from a Gallup poll to demonstrate that the desired family size for Arabs in Israel and Jewish Israelis were the same. The study's population forecast for 2025 predicted that Arabs would comprise only 25% of the Israeli population. Nevertheless, the Bedouin population, with its high birth rates, continues to be perceived as a threat to a Jewish demographic majority in the south, and a number of development plans, such as the Blueprint Negev, address this concern.
