Nate Silver’s Marriage Equality Population Charts

Nate Silver took some time to illustrate just how much of the United States and World’s population has access to equal marriage.

Nate Silver reports via the New York Times:

By Aug. 1, same-sex marriage will be legal in California, Delaware, Maine, Maryland, Minnesota, Rhode Island and Washington — all states where it was not legal one year earlier.

There are about 59 million people living in these seven states, which means that the availability of same-sex marriage in the United States as a percentage of population will have more than doubled within the year. As of early last year, same-sex marriage was legal only in Connecticut, Iowa, Massachusetts, New Hampshire, New York, Vermont and the District of Columbia, which have 35 million people among them.


Earlier this year, France, with a population of about 64 million, became the largest European country to legalize same-sex marriage, and the largest in the world to do so by legislative action.

By August, there will be about 585 million people living in countries or jurisdictions where same-sex marriage is legal. That is roughly double the 289 million people living in such places in August 2012. (These calculations are based on the most recent population estimates and do not account for population growth.)


The availability of same-sex marriage is increasing almost as rapidly on a global scale. It was legalized in Brazil and France earlier this year and will become legal in Uruguay and New Zealand by August.

A decision last month by a Brazilian judicial panel that is generally seen as legalizing same-sex marriage, but could be subject to appeal, is especially important to this math. Brazil has a population of about 194 million — more than the combined 169 million in the nine countries in Europe where same-sex marriage is now legal. The most recent decision followed court rulings that had authorized same-sex marriage in more than a dozen Brazilian states.
