The US Census Bureau reported that the number of same-sex couples in Massachusetts climbed sharply over the past decade; rising 17% to more than 20,000. This is not particularly surprising. Massachusetts continues to lead the nation in passing legislation that protects the rights of the GLBT community (adoption rights, protections in the workplace, marriage equality etc...) As younger gay men and women have come of age - growing up in a socially liberal state where there is less of a stigma it is not surprising to see that many want to move in together or get married.
So despite living through long, cold winters - we're quite the gay old state. If you'd like to read the Boston Globe article link here.
