Based on data from the 2010 US census, the states with the highest percentage of partnered same-sex households are:
- Massachusetts: 1.92%
- Vermont: 1.89%
- New Mexico: 1.84%
- New York: 1.77%
- California: 1.76%
With an honorable mention to the District of Columbia with a fabulous 6.5%.
And the lowest:
- North Dakota: 0.72%
- South Dakota: 0.76%
- Wyoming: 0.87%
- Idaho: 0.91%
- Nebraska: 0.91%
I think the moral of this story is that gay people do settle down, just not in the frozen plains.
Note: These numbers are of a percentage of partnered households (same-sex and opposite-sex, regardless of marriage status), so single households and other types of households are excluded.
Here’s a little map to help you see trends. The darker the purple, the more same-sex couples there are as a percentage of the number of partnered households.
