Lgbt people has smaller life expectancy?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
The best available peer-reviewed and institutional reporting shows evidence that some groups within LGBT populations have experienced higher mortality compared with heterosexual and cisgender peers, but the picture is uneven, historically driven, and limited by poor data collection—especially for transgender people—so it is not accurate to state a single definitive shorter life expectancy for all LGBT people [1] [2] [3].
1. What the data actually show: elevated mortality in some studies, not a universal “shorter lifespan” claim
Multiple population-based reviews and cohort studies report higher mortality for sexual minority populations in certain contexts: a national Danish cohort found same‑sex–marrying men and women had overall mortality rates about 33–34% higher than the general population during the study period [2], and a comprehensive review by USC researchers concluded that across 43 studies the preponderance found elevated mortality for LGBT persons (14 studies showing higher mortality, 28 partially supporting elevated risk) [1].
2. The HIV/AIDS era and urban MSM studies skew earlier life‑expectancy estimates
Some of the stark early estimates of dramatically reduced life expectancy for gay and bisexual men came from urban cohorts during the height of the AIDS epidemic and from analyses that are no longer applicable: the Vancouver study from the late 1980s–early 1990s described life expectancy comparable to men in 1871 Canada because of AIDS deaths, but authors and later observers emphasize that improved antiretroviral therapy and changing epidemiology mean those estimates are not generalizable to today [4] [5].
3. Misuse and myth: the “35 years old” statistic and obituary studies
A widely circulated claim that transgender women of color have a life expectancy of 35 years is not supported by research and was produced by averaging ages of reported murder victims, a method sociologists have criticized as unscientific; mainstream sources specifically flag that reliable life‑expectancy research for transgender people remains lacking [3]. Separate obituary-based analyses and older non‑representative surveys have been used to claim very low median ages of death for homosexuals or lesbians, but such methods are prone to selection bias and are disputed in peer‑reviewed critiques [6] [7].
4. Limits of surveillance and why uncertainty persists
Public health agencies generally do not capture sexual orientation and gender identity on death certificates or in many mortality surveillance systems, making direct life‑expectancy comparisons difficult; experts note that lack of standardized SOGI data hides population patterns and impedes policy responses [8] [1]. Because of these gaps, researchers rely on proxies—marriage records, clinic cohorts, and surveys—that each carry selection biases and temporal confounders [5] [1].
5. Mental health, perceived lifespan and social determinants matter
Beyond raw mortality statistics, multiple reports document worse mental and physical health, greater social isolation, and lower perceived life expectancy among many LGBTQ+ people—particularly bisexual, transgender, nonbinary, and racialized youth—which are risk factors that can translate into mortality differences over the life course [9] [10] [11]. USC researchers stress that higher all‑cause mortality in some studies is not restricted to suicide or substance use but reflects broader health disparities linked to discrimination and unequal access to care [1].
6. What can and cannot be concluded with confidence
It is supported that certain LGBT subpopulations and time periods (notably gay and bisexual men during the pre‑HAART AIDS era and some cohorts seen in administrative data) experienced higher mortality; however, it is not supported to assert a single universal reduced life expectancy number for all LGBT people today, and reliable life‑expectancy research for transgender people is still lacking [4] [3] [1]. The appropriate conclusion is conditional: evidence of elevated mortality and persistent health inequities exists, but incomplete surveillance, historical confounders, and methodological limits prevent a single, definitive life‑expectancy figure for the entire LGBT population [1] [8].
