California has the largest population of any single state and, unsurprisingly, also has the largest gay and lesbian population. Its projected 2.3 million gay and lesbian residents represent 15% of the U.S. gay and lesbian population as a whole. New York follows, with a gay and lesbian population of approximately 1.2 million. However, it is important to note that the distribution of the gay and lesbian population is not purely a coastal phenomenon. There are substantial gay and lesbian populations in states such as Texas, Illinois, Ohio and Georgia.
Same-sex couples are more likely to be found in large metropolitan areas. Around 40% of all same-sex couples live in the 15 largest metropolitan areas, compared to only 30% other households.
