LONDON, APRIL 01
Exactly 20 years ago, one lesbian couple and three gay couples tied the knot in Amsterdam's city hall - making history as the Netherlands became the first country to allow same-sex marriage, a step since followed by nearly 30 other nations.
During the two decades since the law took effect, thousands of gay and lesbian couples have wed in the Netherlands - representing 1.7% of all marriages, according to the national statistics bureau.
About 750 lesbian couples and 620 gay male couples have married on average annually over the last five years, and there are now some 20,000 married same-sex couples living in the country, official data shows.
Over the past five years, more than 400 same-sex marriages have ended in divorce on average annually - with the divorce rate for lesbian couples almost twice as high as that of gay men.
Here are some key facts about the legal recognition of same-sex couples around the world:
Same-sex marriage is legal in 28 countries: Argentina, Australia, Austria, Belgium, Brazil, Britain, Canada, Colombia, Costa Rica, Denmark, Ecuador, Finland, France, Germany, Iceland, Ireland, Luxembourg, Malta, Mexico, Netherlands, New Zealand, Norway, Portugal, South Africa, Spain, Sweden, Uruguay and the United States.
