A record number of U.S. adults (70%) say same-sex marriage “should be recognized by the law as valid” and convey the same rights as “traditional marriages,” according to a Gallup report published June 8.
This is up three points from 2020 and an increase of 43 points since 1996 when Gallup first polled this question.
A majority (53%) of all adults first supported same-sex marriage being legal and conveying the same rights in 2011.
A majority of Democrats (51%) first did so in 2005, increasing to 83% by 2021, while a majority of independents (51%) did so in 2007, rising 22 points over the next 14 years.
For Republicans, 2021 is the first year in which support reached a majority (55%) – a 39-point increase since 1996.
Support is highest among younger respondents (ages 18-34) at 84%, followed by those ages 35-54 (72%) and those 55 and older (60%).
The margin of error is plus-or-minus 4%.
