Marriage by the numbers.

The 2010 census says the US population was 308,746,000. Of course, it has changed a bit since then but for my purposes is good enough.

What percentage of Americans have the legal right, even if they don't have the inclination, to enter a same-sex marriage?

As of now, citizens in Connecticut, the District of Columbia, Iowa, Massachusetts, New Hampshire, New York and Vermont have that right. Republicans are attempting to reimpose regulations in New Hampshire and Iowa to strip away that right. But it doesn't appear to me they will succeed.

According to the Census the population in those states amount to 33,774,000. That is about 11% of all Americans have this right as of now.

It is expected that the Washington state Senate will pass a marriage equality bill in the next few hours. The House will follow and the total should rise to 40,499,000 or 13% of the population. There is a very good chance that Maryland will also support marriage equality in the next few weeks, though not as good as in Washington, where it appears to be a done-deal. If Maryland joins in granting marriage freedom to same-sex couples the number of Americans with this right will grow to 46,273,000 or 15% of the population.
