Since 2000, 16 countries (Argentina, Belgium, Brazil, Canada, Denmark, France, Iceland, Netherlands, New Zealand, Norway, Portugal, Spain, South Africa, Sweden, United Kingdom, Uruguay) have legalized same-sex marriage, as have parts of Mexico. In the United Kingdom, the law legalizing same-sex marriage in England and Wales takes effect March 29, 2014.
In the United States, same-sex marriage is legal in 17 states (California, Connecticut, Delaware, Hawaii, Illinois*, Iowa, Massachusetts, Maryland, Maine, Minnesota, New Hampshire, New Mexico, New Jersey, New York, Rhode Island, Vermont and Washington), and in the District of Columbia. (*Illinois same-sex marriage law takes effect on June 1, 2014. Same-sex marriage was legal in Utah for 17 days following federal court ruling striking down that state’s gay marriage ban. Marriage equality in Utah is on hold pending appeal.)
