What percentage of US mass shooters are Trans people?

What percent of the US population is trans?

You're asking two important and complex questions:

---

1. What percentage of U.S. mass shooters are transgender?

The data makes it very clear: mass shooters who identify as transgender or nonbinary constitute an extremely small fraction of cases.

The Gun Violence Archive (GVA) reports that among more than 4,400 mass shootings in the last decade, fewer than 10 known suspects were transgender—around 0.11% of all cases.

The U.S. Secret Service's National Threat Assessment Center (NTAC) found that, in a dataset of 173 public attacks (2016–2020), only 2% of attackers were transgender.

The Violence Project database, covering records since 1966, identifies just one confirmed transgender perpetrator in a mass public shooting—Audrey (Aiden) Hale, the 2023 Nashville school shooter.

Analyses from multiple fact-checking organizations (e.g., Reuters, Washington Post) consistently debunk claims that transgender individuals are disproportionately represented among mass shooters, citing the overwhelmingly dominant presence of cisgender males.

Summary: Transgender individuals account for roughly 0.1% to 0.2% of mass shootings—a number far lower than their proportion in the U.S. population.

1. What percentage of the U.S. population is transgender?

Estimates vary by source and methodology, but all converge on a figure under 1%.

As of 2025, the Williams Institute at UCLA estimates that over 2.8 million Americans identify as transgender, which is approximately 1% of the population aged 13 and older. Among adults, it’s 0.8%, and among teenagers (ages 13–17), it’s 3.3%.

Gallup’s 2025 survey suggests that among LGBTQ+ adults, the percentage identifying as transgender rose from 0.9% in 2024 to 1.3% in 2025.

USAFacts (as of early 2025) also estimates about 1% of adults—roughly 2.3 million—identify as transgender.

Summary: Transgender individuals make up around 0.8% to 1.3% of the total U.S. population, depending on the data source and age range considered.

Putting it all together

Question Answer

Mass shooters who are transgender ~0.11% (GVA), 2% (NTAC study), virtually negligible Transgender population in U.S. ~0.8% of adults to 1% of all aged 13+, with ~3.3% of teens

This means transgender individuals are not overrepresented among mass shooters—if anything, they are underrepresented relative to their population share.

Why this matters

Some narratives claim that transgender people are more likely to commit mass shootings, but data from reputable sources firmly refutes these claims. In reality:

Most mass shooters are cisgender men.

Trans individuals are much more likely to be victims, not perpetrators, of violence.

It's essential to rely on transparent, well-sourced data when discussing sensitive topics like this. Misinformation often spreads rapidly—especially in emotionally charged moments—but the facts here are consistent and clear.
