Americans of all kinds say same-sex marriage should be legal.
Ten years ago, only a third of Americans (37 percent) thought same-sex marriage should be legal, while more than half (54 percent) opposed the practice.
Today, fewer than a third oppose legal same-sex marriage, according to a June 2017 survey from Pew Research. Two-thirds favor allowing the practice.
Many groups who opposed same-sex marriage changed their minds in the past year, Pew found.
Fifty-six percent of baby boomers, 51 percent of African-Americans, and 48 percent of Protestants now say gay marriage should be legal.
Thirty-nine percent of baby boomers, 41 percent of African-Americans, and 46 percent of Protestants disagree. A year ago, a majority of all three groups opposed same-sex marriage being legal.
White evangelicals (59 percent) still oppose legal same-sex marriage. However, younger evangelicals—those born after 1964—are twice as likely to support legal same-sex marriage (47 percent) as evangelicals born in 1964 or earlier (26 percent).
