健康英语新闻:About nine million Americans identify themselves as lesbian, gay, bisexual or transgender: st

LOS ANGELES, April 7 (Xinhua) -- A new research has found that about nine million people in the United States identify themselves as lesbian, gay, bisexual or transgender (LGBT).

About 1.8 percent of adults identify themselves as bisexual, 1. 7 percent as gay or lesbian, and 0.03 percent as transgender, researchers at the University of California-Los Angeles' School of Law said in the study published by The Los Angeles Times on Thursday.

The study culled data and methods from nine surveys conducted over the last seven years and averaged results from five of those surveys to estimate sexual orientation and from two surveys to estimate the transgender population.

The findings also show that about 8.2 percent of Americans said they participated in same-sex sexual activity and about 11 percent said they had some same-sex sexual attraction, but neither of these groups necessarily identified themselves as LGBT.

The researchers noted that insufficient and inconsistent national surveys make it difficult to get an estimate of the LGBT population in the United States, according to the Times report.
