Is Autism More Common Today Than It Was 20 Years Ago?

July 13, 2025

Yes, the prevalence of autism has increased over the past 20 years. However, this doesn’t necessarily mean that autism itself is more common today. Advances in diagnostic criteria, increased awareness, and better recognition of the autism spectrum disorder (ASD) have contributed to more children being diagnosed at younger ages.

In the past, autism was often underdiagnosed or misdiagnosed, especially in individuals with milder forms of the condition. Today, more children are receiving early assessments, and schools, healthcare providers, and parents are more attuned to the signs of autism. This heightened awareness leads to earlier and more accurate diagnoses.


While the rate of diagnoses has increased, it’s important to note that many experts believe this is a result of better identification rather than a true rise in autism cases.
