The world Jewish population in 2007 is estimated at 13.2 million people, a rise of some 200,000 over 2006, according to a Jewish People Policy Planning Institute report published Sunday.

In the past year, the number of Diaspora Jews shrank by 100,000, while Israel's Jewish population rose by 300,000. Israel is now the home of 41 percent of worldwide Jewry, the report said.

According to a poll conducted by the institute and included in its report, most American Jews fear for the safety of Israel in the wake of the Second Lebanon War and Iran's nuclear program.

Respondents from Jewish communities in Europe and Latin America said they were less inclined to feel an affinity with Israel and they believed radical Islam was being dealt with successfully in their countries.

According to the report, two tiers exist among Jewish communities abroad: A religious one, whose sense of affiliation to Israel is increasing, and another whose Jewish sense of association is weakening and among whom intermarriage is more commonplace.

Institute managing director Avinoam Bar Yosef said the state should allocate more funds to reaching out to the 'second tier' of Diaspora Jews.
