Study: 1.2 million adults identify as non-binary in the U.S.

The big picture: People who identify as nonbinary comprise about 11% of the total population of the LGBTQ adults aged 18 to 60 in the U.S.

• 76% of nonbinary adults in the U.S. are between the ages of 18 to 29.
• 89% live in urban areas.
• "Respondents identified as White (58%) multiracial (16%), Latinx (15%), and Black (9%)," notes the study, adding that "American Indian/Native Alaskan and Asian/Pacific Islanders are under-represented in this report" due to one of the datasets used by the study.

About 55% of respondents said they had been physically attacked or sexually assaulted as adults.

• "Nonbinary LGBTQ adults also experienced stress in childhood, including emotional (82%), physical (40%), and sexual (41%) abuse," per the study.
• 51% had "symptoms consistent with serious mental illness," notes the study.

Researchers looked at findings from two prior surveys with data collected from 2016 to 2018. One survey was on trans adults and one was on lesbian, gay and bisexual adults who aren’t trans.

What they're saying: Joel Baum, senior director of professional development at the nonprofit Gender Spectrum, told the Washington Post the study was significant for increasing visibility of nonbinary people.

• “It’s almost like a stake in the ground, right?” he said. “Saying, ‘Here we are.’”
