Key results include approximately two thirds of Millennials in our sample belonging to the same (non)religious tradition of at least one of their parents. Among the remaining one third who did have a different religious (un)affiliation than their parents at the time of the survey, intergenerational disaffiliation was the most common change present: especially in Canada, but also in the U.S. Intergenerational retention of nonreligion among families where both parents are nonreligious are especially high among Millennials in both countries, a characteristic of this generation’s much more secular social milieu.enreligionsecularswitchingretentionmillennialsconversiondisaffiliationArticle
