What is the average lifespan of a person with autism? There is no single number. Estimates vary by study and by co-occurring conditions. A UK matched-cohort analysis estimated life expectancy for autistic adults without learning disability at about 74.6 years for men and 76.8 years for women. With learning disability, estimates were about 71.7 years for men and 69.6 years for women. These were lower than country averages but not by decades.
In our North Carolina clinic, families ask “What is the average lifespan of a person with autism?” when planning supports. Research shows higher mortality risk in autism overall, with causes including neurologic, respiratory, injury, and suicide. Outcomes differ widely across groups and settings.
One long US cohort reported a younger average age at death, reflecting sample differences and historical care access, not a universal rate. This is why numbers vary.
Bottom Line
What is the average lifespan of a person with autism? It depends on health, support, and co-occurring conditions. Early screening and ongoing care help reduce preventable risks. Call Epic Minds Therapy to build a long-term plan tailored to your family.
