Nearly one in three adults in a global survey believe same-sex couples should be allowed to marry.
In research conducted with almost 100,000 people in 65 countries, it found 32% of people said same-sex marriage should be legal.
45% said it should not be legal, and the remaining 23% replied they did not know.
The International Lesbian, Gay, Bisexual, Trans and Intersex Association said the breakdown shows how deeply continents and regions are divided.
Only 19% of Africans and 26% of Asians said they approved of same-sex marriage, compared to 35% in the Americas, 41% in Europe and 56% in Oceania.
Other findings were:
- 67% of the world agrees human rights should be applied to everyone regardless of their sexual orientation or gender identity or expression.
- 46% of respondents know someone LGB, while only 28% know someone transgender
- 38% of respondents globally feel that adults should be allowed to have private, consensual same-sex relationships.
- Only 26% believe being LGBTI should be a crime.
- And 65% would have ‘no concerns’ if their neighbor was gay or lesbian (ranging from 43% in Africa to 83% in Oceania).
‘Public attitudes in both hostile and friendly nations are not as extremely negative as might have been feared,’ said Renato Sabbadini, Executive Director at ILGA.
‘However, this does not erase the fact that violence and discrimination inflicted on sexually and gender diverse people all around the world continues unabated, and indeed is increasing in places. Too often we still see sexual and gender minorities being convenient scapegoats for leaders who are looking for support from more conservative sectors of their society.’
An ILGA survey published earlier this year found that 2016 was the first time the majority of the world believed it should be legal to be LGBTI. However, two thirds of adults said they would be upset if their child told them they gay or bisexual.
Same-sex marriage is legal in 23 countries around the world.
