Gallup surveyed 50 major metro areas to uncover what percentage of residents identify as not heterosexual. Here are their results (scroll to bottom for the full list of 50).
No surprise that the West is the gayest region. The rootless inheritance of the Frontier makes it attractive for people who want to erase their personal history and associate only with folks who don't know who you are. Gays won't have bad memories of bullies if they uproot themselves from the community that shunned them. The laissez-faire norm of the Wild West also weakens any attempt to contain deviance.
For those following along with the bizarre nature of Mormon culture, you won't be surprised to see Salt Lake City landing in the top 10, at #7, edging out their regional rimjob rival of Denver, CO, as well as Los Angeles. I wonder if that'll be the next big thing for the Utah tourism commission -- "Salt Lake: More gay than LA! (It's official)"
Also not shocking to see how many queers there are in New England, although there aren't quite so many farther down the Bos-Wash corridor.
What might upset your expectations is how gay the plantation South is. New Orleans is all the way up at #4; Virginia Beach and Jacksonville land in the 11-20 spot. Atlanta is a bit more upland than the plantation plains, but still part of the Deep South. Miami, Orlando, and Tampa are also above the median in this list. The only low-ranking metros are Richmond, Raleigh, and Charlotte (although it's fairly upland).
The least gay region is in fact Appalachia, not the Deep South. The most fag-free metros in the nation are Birmingham and Pittsburgh, the southern and northern poles of hillbilly country. Other nearby but lower-elevation areas that rank pretty low include Memphis, Cincinnati, Nashville, and Charlotte. The only nearby areas that rank somewhat high are Louisville, Indianapolis, and Columbus (we've got to do something about that).
Much to the disappointment of Midwestern strivers, the region is about as devoid of homosexuals as Appalachia. The only somewhat high spots are those three sites on the border between the Heartland and Appalachia (Louisville, Indianapolis, and Columbus). In order to appear relevant to the homocentric media, SJWs from wholesome flyover country would have to result to hoaxes a la "my dead gay son" from Sherwood, Ohio.
It's worth comparing the ranking of how gay the population is with the ranking in this earlier post about how prevalent gay culture is. In other words, two cities may have the same concentration of homos in the population, but one may have a much more in-your-face gay culture.
Those differences would reflect the relative strength of enabling vs. containing forces from the surrounding normal population. They would not reflect differences in the dispositions of the gays themselves, since they are everywhere attention whores by inclination. Like how two cities may have similar fractions of the population being black, yet different crime rates, reflecting differences in the strength of the surrounding whites to contain black violence.
For the degree of gay culture, some metro areas rank about where you would expect based on how gay the population is. Salt Lake City is full of fags and has a "vibrant" gay culture, while Cincinnati has few of them and not much of one.
But other places have a much less palpable gay culture than you'd expect from their somewhat high ranking on percent of the population being queer. Boston, Providence, Columbus, and Las Vegas, for example. Las Vegas is too steeped in the commercialization of hetero vice to allow much room for gay culture. Boston's surrounding culture is sober and Puritanical, ditto for Providence. In their classical liberal view, as long as you don't let it show in public, what you do behind closed doors is no one else's business. And Columbus is too happily Middle-American to encourage its weirdos to fly their freak flags. (It didn't make the ranking of gay culture at all.)
On the other hand, several places in the Midwest are host to gay cultures that are far outsized for the tiny gay populations that live there, such as Minneapolis and St. Louis. Madison, Wisconsin was not surveyed by Gallup, but would probably not prove to be very much gayer than nearby Milwaukee. Yet it ranks sixth among cities for signs of gay culture, above San Francisco and Long Beach.
I doubt this is due to the reported gay populations being smaller than the actual size because of self-censorship. These are all liberal bastions that support gay marriage, so respondents would have little reason to lie about who they are.
Rather it seems like another case of Nordic permissiveness run amok, along with Scandinavian insecurity about how others view them, and exaggerating their credentials so that the elites will accept them. "We have pride parades, too!" "Des Moines in the new Brooklyn!" Pathetic.
So, in trying to figure out what factors make for a wholesome regional culture, we need to consider not just how common in the population deviants like homosexuals are, but also how enabling or containing it is of abnormality. This clearly tips the balance in favor of Appalachia over the Midwest as the beacon of cohesion to the rest of the nation that still cares.
