According to a study released today by the Williams Institute (PDF), there are almost nine million LGBT persons in the United States. That works out to 3.5% of the adult population. Via press release:
The Williams Institute, a leading think tank dedicated to the field of sexual orientation and gender identity-related law and public policy, released new research that estimates the size of the lesbian, gay, bisexual, and transgender (LGBT) community in the United States. Drawing on information from four recent national and two state-level population-based surveys, the analyses suggest that there are more than 8 million adults in the US who are lesbian, gay, or bisexual, comprising 3.5% of the adult population. There are also nearly 700,000 transgender individuals in the US. In total, the study suggests that approximately 9 million Americans – roughly the population of New Jersey – identify as LGBT.
The study notes: “Estimates of those who report any lifetime same-sex sexual behavior and any same-sex sexual attraction are substantially higher than estimates of those who identify as lesbian, gay, or bisexual. An estimated 19 million Americans (8.2%) report that they have engaged in same-sex sexual behavior and nearly 25.6 million Americans (11%) acknowledge at least some same-sex sexual attraction.”
