(CNN) — As Hawaii and Illinois join the list of states approving same-sex marriage, the United States crosses a big mark on the issue: More than 1 in 3 Americans will live where same-sex marriage is legal.
It’s a dramatic shift in a short period of time — one not seen on other social issues.
Hawaii’s Legislature passed the measure Tuesday. Gov. Neil Abercrombie signed it into law Wednesday morning. It will go into effect December 2.
Illinois Gov. Pat Quinn plans to sign legislation for his state November 20. It will take effect June 1.
In all, 16 states and the District of Columbia now have legal same-sex marriage.
It’s banned in other states, except New Mexico, which has no state law either way. Some counties in New Mexico have begun allowing same-sex marriage.
