The support for same-sex marriage in the United States increased overall between 2016 and 2024. However, there was a decrease in support across both parties in 2024. According to a survey conducted across the years, this increase was particularly relevant among Republicans. This was consistently the party group least in favor of gay marriage, but in 2021, for the first time, a slight majority of Republicans showed support for it. In 2024, 83 percent of the Democrats' electorate thought that same-sex marriage should be recognized by the law as valid.
