Doh! Who'da thunk it?! From Advocate Online:
A study that shows the percentage of people in the nation's largest cities identifying as gay, lesbian, or bisexual lists San Francisco on top with 15.4%, with Seattle coming in second with 12.9%. Atlanta was third with 12.8%, and Minneapolis fourth with 12.5%. Four of the top 10 cities were in California, while all but Boston and Atlanta were west of the Mississippi River.
The Williams Institute on Sexual Orientation Law and Public Policy at the University of California, Los Angeles, used census and other federal information to estimate the numbers.
The census data on same-sex couple households showed that between 2000 and 2005 the number reported increased by 30%. New Hampshire had the largest jump in same-sex couples, with 106% over the five years studied, with heartland states like Nebraska, Kansas, Indiana, and Iowa also showing substantially increased numbers.
The findings do not show a sharp increase in the number of gays, lesbians, and bisexuals in general. Instead, the study suggests, people are more willing to disclose their sexual orientation in government surveys.
More facts from Wikipedia:
San Francisco is a minority-majority city as non-Hispanic Whites make up less than 44% of the population. Asian Americans, principally Chinese, comprise nearly 31% of the population. Hispanics of any race make up just over 14% of the population. At less than 8% of the population, San Francisco has a lower concentration of African Americans than the United States as a whole. Few of San Francisco's residents have lived there their whole lives. Only 35% of its residents were born in California; 39% were born outside the United States.
San Francisco has the highest percentage of same-sex households of any American county, with the Bay Area having a higher concentration than any other metropolitan area. Gay men outnumber lesbians; it has been estimated that one in five males over the age of 15 is gay.
(The "City and County of San Francisco" occupies the tip of the San Francisco Peninsula and measures approximately 7 by 7 miles, with a population of 739,426. By comparison, the City of Miami is slightly smaller in land (i.e., not including water) area and contains an estimated 379,724 inhabitants. With five boroughs (or counties), New York City has a population of over 8 million within an area of 321 square miles, making it the most densely populated major city in North America (with Manhattan being the most densely populated county in the U.S.). San Francisco is the second most densely populated major city in the U.S. [mostly from Wikipedia] [photo of Coit Tower courtesy of me])
