The U.S. Religious Landscape Surveyfinds that more than one-in-four (27%) American adults who are married or living with a partner are in religiously mixed relationships. If people from different Protestant denominational families are included – for example, a marriage between a Methodist and a Lutheran – nearly four-in-ten (37%) couples are religiously mixed. The survey, conducted by the Pew Research Center’s Forum on Religion & Public Life, finds that people who are unaffiliated with a particular religion are the most likely (65%) to have a spouse or partner with a different religious background. Buddhists (55%) also are likely to be married or living with a partner with a religious background different from their own. In contrast, the individuals least likely to marry or live with a partner outside their faith include Hindus (only 10% are married to or live with someone of a different religion), Mormons (17%) and Catholics (22%).
