How Long Do People with Autism Live? Facts & Stats

What is the average lifespan of a person with autism? Research shows that autistic individuals often have a shorter average lifespan compared to the general population, but this varies widely depending on factors like co-occurring conditions and level of support.



• Studies indicate the average lifespan for autistic people ranges roughly between 39 and 75 years, depending on severity and coexisting conditions.
  
  
• Those with more severe autism or intellectual disabilities tend to have shorter life expectancy, sometimes as low as the late 30s to 50s range.
  
  
• Autistic individuals without intellectual disabilities can live into their 70s, but generally, life expectancy is estimated to be slightly lower (by about 6-10 years) than neurotypical peers.
  
  
• Common health issues affecting lifespan include epilepsy, accidents, respiratory problems, and chronic conditions.
  
  
• Access to quality healthcare, early intervention, and ongoing support play a critical role in improving life expectancy and quality of life for autistic individuals.
