Until 2018, the U.S. Census Bureau had never surveyed individuals regarding their sexual orientation. For the first time, however, in 2018 Census estimates, the agency surveyed co-habiting couples regarding the sex of their partner. In the 2020 Census, survey questions expanded to include the sex of partners among married couples.
The most detailed survey offering any view of Los Angeles County’s LGBTQ population was a Gallup survey of more than 374,000 people, conducted from June 2012 through December 2012. The survey asked the question, "Do you, personally, identify as lesbian, gay, bisexual or transgender?" It focused on the 50 largest metropolitan areas in the United States, including the Los Angeles area. The survey found the Los Angeles-Long Beach-Anaheim metropolitan area (Los Angeles and Orange Counties) to rank eighth among America’s 50 largest metro areas, with 4.6 percent of its population identifying as LGBTQ. Although Gallup, at the time, put the national average that identified as LGBTQ at 3.6 percent, its 2020 survey updated that to 5.6 percent (likely also increasing the L.A. metro area percentage).
If we were to apply the 4.6 percent survey finding against the most recent U.S. Census estimate (2021) for Los Angeles County’s adult population, we could estimate that 361,125 adult residents of the county are LGBTQ. A 2012 report by the Los Angeles County Department of Public Health then estimated that 14,428 county residents were transgender.
