From The Economist:
Same-sex marriage is now legal nationwide in 11 countries, including Argentina and South Africa, as well as in parts of a further two. In Mexico it is allowed in the capital. In America nine states and the District of Columbia have legalised it, including three which, for the first time, did so by popular vote on November 6th, ending a succession of electoral defeats for the measure in 32 states. In Catholic France the new Socialist government has just approved a bill to permit same-sex marriage. That said, in 78 countries—mostly in the Muslim world, Africa and other developing states—gay sex is still a crime, punishable by long prison terms and even death. Opposition to gay marriage remains fierce. But attitudes are changing—and fast.
