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

Yes, autism diagnoses are significantly more common today than they were two decades ago. Current data from the Centers for Disease Control and Prevention (CDC) show that about 1 in 31 children are now identified with Autism Spectrum Disorder (ASD). CDC+2National Institute of Mental Health+2

Back around the year 2000, estimates placed prevalence at about 1 in 150 children. Statista+1

Why the jump? Several factors are at play:

  • Wider diagnostic criteria and increased recognition of autism’s milder forms
  • Greater awareness among parents, teachers and healthcare providers
  • Improved screening and early intervention services

These changes mean more children who previously would have gone unrecognized are now receiving diagnoses and support. That said, it’s less clear how much of the increase reflects a true rise in occurrence versus improved identification.

At Steady Strides ABA, we focus on early diagnosis and evidence‑based intervention for children, so no matter when a child is diagnosed, they can begin strong, personalized support with ABA therapy in Maryland.
