In this article, we will look at the 20 countries with the highest approval of same sex marriages and examine trends in public approval for gay and lesbian weddings around the world.

Approval of Gay and Lesbian Marriages in the U.S.

Public approval rates for same-sex marriages differ across the world, showing drastic variations. Although the Supreme Court legalized same-sex marriage in the United States in 2015, data collected by the Pew Research Center shows that only 63% of individuals support it, with 34% standing against it. These sentiments are significantly skewed by religious and political beliefs. For instance, supporters of the Democratic Party are almost twice as likely to approve of same-sex marriages as opposed to the Republicans. While 82% of Democrats support same-sex marriage, only 44% of Republicans express the same sentiments. Age also plays a pivotal role in the approval of gay marriages, as around 73% of Americans below the age of 40 stand in support of gay and lesbian marriages, considering it legal. This translates to about three-quarters of the total population of the United States below the age of 40. In contrast, only 57% of U.S. citizens above the age of 40 give their approval for same-sex marriages.

Geographical Breakdown of Public Approval of Same Sex Marriages 

Public sentiment about gay and lesbian weddings also varies across different geographical regions in the world. Countries in Western Europe openly support same-sex marriages, with Sweden taking the lead with 92% supporters. According to data by the Pew Research Center, nearly eight in ten individuals in the country express their approval for same-sex marriages. The Netherlands, Spain, and France trail behind, with 89%, 87%, and 82% of their total population supporting lesbian and gay weddings. Germany also makes the list, with around 80% of people in the country approving same-sex marriages. Same-sex marriage in all of these countries is legal. However, not all European countries have legalized gay and lesbian marriages. The practice is illegal in Poland and Hungary, with 41% and 31% of people supporting it, respectively.

In North America, gay and lesbian marriages are legal in Canada, the United States, and Mexico. Around 79% of Canadians support same-sex marriages, while the sentiment in USA and Mexico stands at 63%.

Indonesia is the Asian country with the highest percentage of people who oppose gay and lesbian marriages, with around nine in ten people opposing LGBTQ+ people marrying openly. Only 5% of Indonesians support same-sex marriage.

South Africa is the only African country where gay and lesbian marriages are legal. Despite the official ruling in 2006, around 59% of South Africans oppose the cause. In fact, homosexuality is illegal in Nigeria, where only 2% of adults support same-sex marriage. Kenyans follow the same road, with only 9% in favor of same-sex marriages. In the Middle East, 56% of Israelis do not support the prospect of legalizing gay marriage, with religious affiliations and politics playing a major role in driving such sentiments.

Ups and Downs in Public Support 

Despite a significant majority of U.S. residents supporting the LGBTQ+ community, the ordeal has hit some bumps over the years. In 2023, Target Corp. (NYSE:TGT) faced a country-wide boycott and media backlash after it decided to sell specialized swimsuits for trans people. The retailer was accused, albeit falsely, of selling the swimsuits to children, with other children’s Pride-theme clothing containing slogans like “Just be you” and “Trans people will always exist!.” On May 10, Bloomberg reported that Target Corp. (NYSE:TGT) had decided to sell its LGBTQ-themed clothing in only select stores across the country. The merchandise this year would only be available for adults after the retailer had to suffer a dent in revenue due to a nationwide boycott.
