I wish I had thought of doing it this way! I have often reported on the global growth in gay marriage, and looked for ways to present it in a simple graphic. Nate Silver at fivethirtyeight has found the simple key – convert the jurisdictions, whether countries, provinces or cities, to the populations living under them, and treat all of Europe as a single entity.
This is the colourful chart that resulted:
That’s 250 million people who now live in locations where legal recognition for gay marriage has been agreed. (More are on the way. Finland this week was just the latest to declare an intention to change the law.) Please note the rather prominent band of yellow – South Africa.
I have only two quibbles with this. Nate refers to the “slow” growth to equality. But going from roughly one million at the start of 2007 to two and a half million now, I would describe as rapid. I would also stress that this applies to full marriage only: it would be interesting to see a similar chart which included civil unions.
