Despite their strong pro-family values, evangelical Christians have higher than average divorce rates -- in fact, being more likely to be divorced than Americans who claim no religion, according to findings as cited by researchers from Baylor University.
The research is part of a new report released by the Council on Contemporary Families.
The council report coincides with the 50-year anniversary of the passage of the Civil Rights Act, which made it illegal to discriminate against individuals on the basis of race, national origin, religion or gender. The council's report, which included findings by a dozen researchers, dealt with changes in the past half century for each of the populations affected by the law: religious groups, racial and ethnic minorities and women.
