half of all American adults say they are married

Religiously unaffiliated voters make up increasing share of Democrats A new Pew Research Center analysis of trends in voters’ political party identification over time includes several findings about religion. For one, religiously unaffiliated voters make up an increasing share of Democrats – now fully a third. In addition, while white evangelical Protestants have been moving even more heavily toward the Republican Party, Mormons – though still solidly Republican – have become somewhat less likely to identify with the GOP in recent years. The report also includes political trends among white mainline Protestants, black Protestants, Catholics and Jews.

Share of married adults varies widely across U.S. religious groups Roughly half of all American adults say they are married, according to the 2014 Religious Landscape Study. But among those 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.
