(CNN) -- The Supreme Court earlier this year gave proponents of same-sex marriage two major victories -- striking down parts of the Defense of Marriage Act that denied the same benefits provided to heterosexual spouses to legally married same-sex couples, and allowing same-sex marriages to resume in California.
Here's a look at same-sex marriage in the United States, by the numbers:
36 -- The number of U.S. states that have banned same-sex marriage, either through legislation or constitutional provisions.
6 -- The number of U.S. states that allow civil unions between same-sex couples, but not marriage: Colorado, Delaware, Hawaii, Illinois, New Jersey and Rhode Island. This number will go down to four this summer after Delaware's new marriage laws take effect in July and the Rhode Island laws do on August 1. (Some states that allow civil unions also ban same-sex marriage.)
12 -- The number of U.S. states that allow same-sex marriage, along with the District of Columbia: Connecticut, Delaware, Iowa, Maine, Maryland, Massachusetts, Minnesota, New Hampshire, New York, Rhode Island, Vermont, and Washington.
1,138 -- The number of federal benefits to marriage.
30.25% -- The approximate percentage of the U.S. population affected by Wednesday's Supreme Court rulings after same-sex marriage laws take effect in Delaware (on July 1, 2013) and Minnesota and Rhode Island (on August 1, 2013).
2001 -- The year the Netherlands made same-sex marriage legal. It was the first country in the world to so.
2003 -- The year that the U.S. Supreme Court ruled that it is unconstitutional to criminalize sodomy.
2004 -- The year that same-sex marriage became legal in Massachusetts, the first U.S. state to do so.
14 -- The number of countries worldwide where same-sex marriage is legal in the entire country. They are: Argentina, Belgium, Canada, Denmark, France, Iceland, the Netherlands, New Zealand, Norway, Portugal, South Africa, Spain, Sweden, and Uruguay.
3 -- The number of countries where same-sex marriage is legal in some areas: Brazil, Mexico and the United States.
27% -- The percentage of Americans who thought same-sex marriage should be legal in 1996, according to a May Gallup Poll.
53% -- The percentage of Americans who think it should be legal in 2013, according to the same poll.
