Sociologists at the University of Texas and the University of Iowa write in the American Journal of Sociology that "Conservative religious beliefs and the social institutions they create .... increase divorce risk in the contemporary United States."
Others suggest that conservative Southern states have higher rates of divorce than the Northeast because the bluer region has lower rates of marriage. They further suggest that class is a big factor and that poverty contributes to family dysfunction.
Q: Is religion bad for marriage?
While the study controlled for factors such as income and education level, it did not make any distinction about a person's commitment to their faith. Rather, participants self identified their religious affiliation and were identified as "conservative Protestants" if they answered in the affirmative to questions such as: "Do you believe the Bible contains no errors?"
