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. Key findings from the study include among adults who identify as lesbian, gay, or bisexual, bisexuals comprise a slight majority (1.8% compared to 1.7% who identify as lesbian or gay); women are substantially more likely than men to identify as bisexual; 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.
