An overwhelming majority of people in Northern Ireland now back same-sex marriage, according to a new Ipsos MORI poll.
Support appears to have increased since the Republic of Ireland's referendum - and the results show that even more people here would vote 'Yes' than in the south.
The latest survey found that 68% of adults in Northern Ireland believe same-sex couples should be allowed to marry - compared to the 62.1% 'Yes' vote in the Republic.
The figure rises to 82% among 16 to 34-year-olds and 75% support among 35 to 54-year-olds, but falls to 47% among those aged 55 and over.
Last month thousands of people marched through Belfast in a rally for marriage equality. Northern Ireland will soon be the only part of the UK or Ireland where gay couples are denied civil marriage.
Amnesty International has said the figures show Northern Ireland's politicians are "badly out of step with ordinary people" on the issue.
“The people have spoken and it’s clear they don't want Northern Ireland to be left behind on marriage equality," said Patrick Corrigan, Amnesty's Northern Ireland programme director.
“Continuing resistance to bringing Northern Ireland in step with all our neighbours is unacceptable. It’s high time Northern Ireland said a big ‘we do too’ to equality.
"The Stormont Executive should bring forward marriage equality legislation without further delay.”
The poll found that people living in Greater Belfast are more likely to back gay marriage than those living in other areas of Northern Ireland - at 75% versus 63% respectively.
Meanwhile, those from a Catholic background are more inclined to voice support for gay marriage, with three quarters (75%) agreeing that homosexual couples should be able to get married, compared to 57% of those from a Protestant community background.
The data also highlighted differing views on this subject depending on the political party participants voted for in May’s Westminster Election.
Support is highest among those who voted for Sinn Fein (80%), Alliance (79%) and SDLP (61%), compared to 49% of UUP voters and 45% of DUP voters.
Attitudes appear to have changed significantly since a 2014 Belfast Telegraph/Lucid Talk poll. Then, 50.5% were found to be in support with 49.5% opposing gay marriage.
Ipsos MORI's 2015 poll interviewed a representative sample of 1,000 adults aged 16+ across Northern Ireland. Interviews were conducted face-to-face between May 20 and June 8 2015. Data are weighted to match the profile of the population.
