The September 2007 issue of the Journal for the Scientific Study of Religion includes a study by Ph.D. student Richard J. Petts and assistant professor Chris Knoester of The Ohio State University on the question of religious heterogamy between parents, or the effects of parents being "unequally yoked" on their children.

The study produced surprising results. Children of religiously unmatched parents did not manifest lower grades, lower self-esteem, or lower satisfaction. But they were far more likely to use marijuana and engage in underage drinking.
I interviewed Richard Petts about his findings.
Are religiously heterogamous unions on the rise? If so, why do you think that is?
All signs point to a sizeable increase in religiously heterogamous marriages, although detailed numbers are hard to come by.
There are a number of reasons for this increase. First, increased individualism among Americans starting in the 1960s led to a greater focus on spirituality and personalized religious practices. This led many people to turn away from traditional churches, and also helped to increase acceptance of religious diversity.
Moreover, religious affiliation as an identifying characteristic seems to have declined in importance. For example, ...
