A survey conducted by the Israel Democracy Institute and released this week found that one fifth of Israeli Jews identify as belonging to the national-religious sector, a significantly higher figure than was previously thought. The new study published on Tuesday also revealed attitudes within the national-religious community on a variety of issues such as settlements, rabbinic influence on national policy, civil marriage and other matters relating to religious life in Israel. The survey was conducted in 2013 on a sample group of 978 respondents who identified themselves as belonging to the national-religious sector out of a representative nationwide sample of 4,597 adults residing in Israel. According to the IDI, prior to the study it was believed that the national religious community comprised approximately 10 percent of the Israeli Jewish population according to data from the Central Bureau of Statistics. But in the new survey, the institute found that 21% of Israeli Jews state that, to a large or very large extent, they belong to the National-Religious sector in terms of both their lifestyle and outlook, while 23% state they belong to a slight extent, and 53% state they do not belong at all.
