The study gathered data from nine surveys conducted over the last seven years. Interesting, the study found that bisexuals make up 1.8% of the population, while 1.7% are gay or lesbian. Transgender adults make up 0.3% of the population.
Beyond those identifying as LGBT, 8.2% of Americans report participating in same-sex sexual activity and an estimated 11% of adults held some same-sex sexual attraction. Neither of these officially identified as LGBT.
Despite the confusing statistics, the study's researchers did note that there are insufficient and inconsistent methods for actually determining the true numbers of LGBT people.
