Jeffrey M. Jones at Gallup:
Gallup's latest update on lesbian, gay, bisexual or transgender identification finds 5.6% of U.S. adults identifying as LGBT. The current estimate is up from 4.5% in Gallup's previous update based on 2017 data.
Currently, 86.7% of Americans say they are heterosexual or straight, and 7.6% do not answer the question about their sexual orientation. Gallup's 2012-2017 data had roughly 5% "no opinion" responses.
The latest results are based on more than 15,000 interviews conducted throughout 2020 with Americans aged 18 and older. Gallup had previously reported annual updates from its 2012-2017 daily tracking survey data, but did not routinely measure LGBT identification in 2018 or 2019.
