Overview.
Public opinion of same-sex marriage in the United States has changed radically since polling of the American people regarding the issue was first conducted in 1988. The issue of same-sex marriage was not brought up as an issue for public debate until at least the 1950s and wasn't a political issue until the 1970s. According to statistician Nate Silver of the poll aggregator "FiveThirtyEight", from 1988 to April 2009, support for same-sex marriage increased between 1% and 1.5% per year and about 4% from April 2009 to August 2010. A Pew Research Center poll, conducted from May 21, 2008 to May 25, 2008, found that, for the first time, a majority of Americans did not oppose same-sex marriage, with opposition having fallen to 49%.<ref name="PEW RESEARCH CENTER FOR THE PEOPLE & THE PRESS MAY 2008 POLITICAL/BELIEVABILITY SURVEY FINAL TOPLINE May 21–25, 2008"></ref> An ABC News/"Washington Post" poll, conducted from April 21, 2009 to April 24, 2009, found that, for the first time, a plurality of Americans supported same-sex marriage at 49% and that a majority of Americans supported the marriages of same-sex couples validly entered into in one state being recognized in all states at 53%.

In 1996, 68% of Americans opposed same-sex marriage, while only 27% supported. In 2018, 67% of Americans supported same-sex marriage, while only 31% opposed. As of 2018, 60% of Americans said they would not mind if their child married someone of the same gender.
