What is the Average Lifespan of a Person with Autism?

November 28, 2025

Families often ask about the average lifespan of individuals with autism. Research suggests that autistic people may face a shorter life expectancy compared to the general population, with studies estimating ranges between 39 and 75 years. This difference is often linked to coexisting health conditions, challenges with mental health, and limited access to appropriate medical and social support.

It’s important to note that autism itself is not life‑threatening. Factors such as epilepsy, anxiety, depression, and higher risks of accidents or self‑injury can influence outcomes. With strong family involvement, effective therapies, and access to healthcare, many autistic individuals live long, fulfilling lives.


Applied Behavior Analysis (ABA) therapy plays a vital role in improving quality of life. By teaching communication, daily living, and social skills, ABA helps reduce risks associated with isolation and stress. Families, educators, and professionals can make a significant difference by focusing on strengths and building supportive environments.


At Achieve Behavioral Therapy, we are dedicated to serve and committed to empowering autistic individuals to thrive through ABA therapy in New Jersey and North Carolina.
