Among Jewish youths, support for the definition of Israel as a Jewish state as the most important goal for the country grew from 18.1 percent in 1998 to 33.2 percent last year, the survey reports. At the same time, there has been a consistent drop in those who back the importance of Israel's identity as a democratic country - from 26.1 percent in 1998 to 14.3 percent in 2010.

Support for Israel to eventually live in peace with its neighboring countries also fell significantly, from 28.4 percent 12 years ago to 18.2 percent last year. This is the third such survey of young people conducted by the two organizations in the past 12 years.

The study was carried out in July 2010, among a representative sample of Jewish and Arab youth. It included 1,600 participants, 800 aged 15-18 and 800 21-24, which is considered a relatively large group.
