One in four high school students identifies as homosexual, bisexual or is currently questioning their sexuality, according to new data.

The Centers for Disease Control and Prevention’s annual report of 17,232 students found that about three-quarters of teens aged 14 to 18 in 2021 claimed to be attracted only to the opposite sex.

Of the remaining respondents, nearly 12% considered themselves bisexual, just over 3% were either gay or lesbian and 9% marked “other” — which could include those who identify as pansexual and asexual — or “questioned” their sexuality.

The latest figures marked a record number of youngsters who do not identify as straight — approximately one in four students.

The number of LGBTQ+ people continues to rise every year. A Gallup poll released in February showed that 7.2% of adult Americans are “something other than heterosexual,” the highest concentration of which belonged to Gen Z.

But the uptick in LGBTQ+ youth may not mean that fewer people are heterosexual — rather, it indicates that more people are comfortable with being openly honest about their sexual orientation and identities. This seems to be especially true among the younger generation who are chronically online.

“Social media has added to this visibility that there are options that were not previously available,” Ritch Savin-Williams, a developmental psychology professor at Cornell, previously told The Post. “In a positive sense, it sort of says, ‘Hey, look, you don’t have to fit into these boxes.’

Despite arguments that being queer is a passing fad, Savin-Williams noted that it’s “not that the absolute number of people” who identify as non-heterosexual has grown, it’s that more people are willing to express and “declare” it.

Yet, the trend towards tolerance could be dashed away in places like Florida, where the “Don’t Say Gay” bill continues to drum up controversy, as concerned parents and activists argue that it could make LGBTQ+ youth feel less welcomed.

In the Youth Risk Behavior Surveillance System (YRBSS), the CDC urged schools to create a “more inclusive” environment for LGBTQ+ youth, recommending initiatives such as gender and sexuality alliances, curating safe spaces and enforcing anti-harassment policies.

The agency also found that nearly 70% of LGBQ+ students “experienced persistent feelings of sadness or hopelessness” and more than half endured poor mental health.

LGBTQ+ students were more likely to experience sadness and hopelessness, poor mental health, substance abuse, sexual violence, bullying and suicidal thoughts or behaviors.

When compared to past years, many of the categories trended upward in the “wrong direction.”

“As in previous reports, we continue to see disparities among students who identify as lesbian, gay, bisexual, questioning, or another non-heterosexual identity, or who have had any same-sex sexual partners compared to their peers,” the authors wrote in the report.
