Gallup today issued the results of a poll conducted last year in which they asked over 200,000 people if they "personally identify" as LGBT. As with all such self-disclosure surveys, the numbers are somewhat skewed by those who decline to out themselves to pollsters.
The percentage of U.S. adults who identify as lesbian, gay, bisexual, or transgender (LGBT) ranges from 1.7% in North Dakota to 5.1% in Hawaii and 10% in the District of Columbia, according to Gallup surveys conducted from June-December 2012. Residents in the District of Columbia were most likely to identify as LGBT (10%). Among states, the highest percentage was in Hawaii (5.1%) and the lowest in North Dakota (1.7%), but all states are within two percentage points of the nationwide average of 3.5%.Gallup observers that while the variation between most states is relatively small, their data does support a conclusion that LGBT people are more willing to self-identify in states that provide anti-discrimination protections.
Measuring sexual orientation and gender identity can be challenging because these concepts involve complex social and cultural patterns. There are a number of ways to measure lesbian, gay, and bisexual orientation, and transgender status. Gallup chose a broad measure of personal identification as LGBT because this grouping of four statuses is commonly used in current American discourse, and as a result has important cultural and political significance.
One limitation of this approach is that it is not possible to separately consider differences among lesbians, gay men, bisexuals, or transgender individuals. A second limitation is that this approach measures broad self-identity, and does not measure sexual or other behavior, either past or present.
The states with proportionally larger LGBT populations generally have supportive LGBT legal climates. With the exception of South Dakota, all of the states that have LGBT populations of at least 4% have laws that prohibit discrimination based on sexual orientation and gender identity and allow same-sex couples to marry, enter into a civil union, or register as domestic partners. Of the 10 states with the lowest percentage of LGBT adults, only Iowa has such laws.Fascinating stuff. Hit the link for much more and the second half of Gallup's ranking.
