Abstract
Data from the 1972–98 General Social Surveys document changes in attitudes toward premarital, extramarital, homosexual, and teenage sex. This analysis demonstrates the liberalizing effect of cohort succession but also finds intracohort change in attitudes as the birth cohorts age. Intracohort change dominated recent dramatic declines in disapproval of homosexuality. As theories of individualism and postmaterialism suggest, higher education, secularism, and relative income are associated with greater tolerance of homosexuality. Although the young and those who do not attend religious services frequently led the 1988–98 declines in disapproval of same-sex relations, the diffusion of permissive values from higher to lower education groups is also evident.
