Throughout U.S. history, marriage has been tied to religion and religious institutions. Today, virtually all faith traditions have rules and ceremonies regarding marriage and, in the United States as well as in many other countries, clergy of different religious groups are authorized by the government to perform weddings.
In the U.S., roughly half of all American adults (48%) say they are married, according to the 2014 Religious Landscape Study. Much smaller shares of U.S. adults say they are living with a partner (7%), are divorced or separated (13%), or are widowed (7%). A quarter of Americans say theyve never been married.
In certain U.S. religious groups, a higher-than-average share of adults say they are married. For instance, six-in-ten or more Mormons, members of the Presbyterian Church (U.S.A.), and members of the Evangelical Lutheran Church in America are married. The same holds true for Hindus, Southern Baptists and members of the Episcopal Church.
...Age also is a big factor in determining which religious groups have a higher or lower share of married adults. In short, those groups that have more young people tend to have a smaller share of married adults and vice versa. Thats in part because younger Americans are less likely than their older counterparts to be married. In fact, among adults between the ages of 18 and 29, just 16% are married, compared with a majority (57%) of adults over the age of 30.
Side note: it is interesting to see which groups have the highest divorce rates too.
