[Ed. – Since the estimate depends entirely on self-diagnosis, why not make it 100% and claim the rest of us just aren’t ‘woke’?]
The percentage of American adults identifying as lesbian, gay, bisexual or transgender (LGBT) increased to 4.5% in 2017, up from 4.1% in 2016 and 3.5% in 2012 when Gallup began tracking the measure. The latest estimate is based on over 340,000 interviews conducted as part of Gallup’s daily tracking in 2017.
Gallup’s LGBT estimates are based on those respondents who say “yes” when asked, “Do you, personally, identify as lesbian, gay, bisexual or transgender?” Extrapolation to the latest census estimate of adults 18 and older in the U.S. suggests that more than 11 million adults identify as LGBT in the country today.
The expansion in the number of Americans who identify as LGBT is driven primarily by the cohort of millennials, defined as those born between 1980 and 1999. The percentage of millennials who identify as LGBT expanded from 7.3% to 8.1% from 2016 to 2017, and is up from 5.8% in 2012. By contrast, the LGBT percentage in Generation X (those born from 1965 to 1979) was up only .2% from 2016 to 2017. There was no change last year in LGBT percentage among baby boomers (born 1946 through 1964) and traditionalists (born prior to 1946).
