Nationally representative telephone survey of 3,290 English & Spanish-speaking teenagers between the ages of 13-17, and their parents. Also includes 80 oversampled Jewish households, not nationally representative, bringing the total number of completed cases to 3,370. Purpose is to research the shape & influence of religion & spirituality in the lives of American youth; to identify effective practices in the religious, moral, and social formation of the lives of youth; to describe the extent & perceived effectiveness of the programs & opportunities that religious communities are offering to their youth; and to foster an informed national discussion about the influence of religion in youth's lives, in order to encourage sustained reflection about and rethinking of our cultural and institutional practices with regard to youth & religion. The 2nd wave was designed to be a re-interview of all Wave 1 youth survey respondents. Parents of the youth respondents were not re-interviewed. At the time of the 2nd survey, respondents were between the ages of 16-21. Conducted from June 9-November 24, 2005. 2nd wave interviews were conducted only in English. Four youth respondents did not participate in the Wave 2 interview due to not being able to understand or speak English. Wave 2 covers many of the same topics as Wave 1. Many of the questions are identical. However, Wave 2 was re-designed to take into account changes in the lives of the respondents as they began to enter young adulthood. Wave 2 included new questions pertaining to behaviors occurring during the transition to adulthood, such as non-marital cohabitation, educational and career aspirations, pregnancy and marriage. In Wave 3 every attempt was made to re-interview all English-speaking Wave 1 youth survey respondents. At the time of the 3rd survey, respondents were between the ages of 18-24. Conducted from September 24, 2007-April 21, 2008. Wave 3 replicated many of the questions asked in Waves 1 & 2 with some changes made to better capture the respondents' lives as they grew older. For example, there were fewer questions on parental monitoring and more on post-high school educational aspirations.
