# Public opinion of same-sex marriage in the United States

Public opinion of same-sex marriage in the United States has significantly changed since the 1990s, and a majority of Americans now favor same-sex marriage.
Approval of same-sex marriage is higher in younger generations; in the 2022 General Social Survey, almost 80% of 18–34 year olds either agreed or strongly agreed that same-sex couples should have the right to marry. From 1988 to 2009, support for recognized same-sex marriage increased between 1% and 1.5% per year, and accelerated thereafter, rising above 50% in Pew Research Center polling for the first time in 2011. A 2022 Public Religion Research Institute poll found that a majority of people in every state support same-sex marriage except in Mississippi, where there is plurality support.
A 2023 New York Times/Siena poll found that 70% of Americans support same-sex marriage and 22% oppose it. Garretson (2018) writes: "The transformation of America's response to homosexuality has been — and continues to be — one of the most rapid and sustained shifts in mass attitudes since the start of public polling." However, support for same-sex marriage has fallen slightly in the 2020s, indicating a stagnation of the previously growing support for gay marriage.

## 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 was not 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%. 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%. A CNN/Opinion Research poll, conducted from August 6, 2010, to August 10, 2010, found that, for the first time, a majority of Americans supported same-sex marriage at 52%. A Greenberg Quinlan Rosner Research poll, conducted from January 25, 2015 to January 31, 2015, found that, for the first time, 60% of Americans supported same-sex marriage. This was five months before the landmark June 26, 2015 Supreme Court decision, Obergefell v. Hodges, which ruled that the fundamental right to marry is guaranteed to same-sex couples by both the Due Process Clause and the Equal Protection Clause of the Fourteenth Amendment of the Constitution. The 5–4 ruling required all 50 states, the District of Columbia, and the Insular Areas to perform and recognize the marriages of same-sex couples on the same terms and conditions as the marriages of opposite-sex couples, with equal rights and responsibilities. Prior to Obergefell, same-sex marriage had already been established by statute, court ruling, or voter initiative in 36 states, the District of Columbia, and Guam.
Continual polling by Gallup over the course of more than two decades has shown that support for same-sex marriage has grown rapidly, while opposition has simultaneously collapsed. 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.
