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

Yes,  autism is diagnosed far more frequently today than it was 20 years ago. According to the Centers for Disease Control and Prevention (CDC), autism now affects about 1 in 36 children, compared to roughly 1 in 150 in the early 2000s.


However, this increase doesn’t necessarily mean autism itself is becoming more common. Experts believe the rise is largely due to better awareness, improved screening tools, and broader diagnostic criteria. In other words, more children are being accurately identified and getting the support they need earlier.



Society’s understanding of Autism Spectrum Disorder (ASD) has also evolved. Conditions once diagnosed separately, like Asperger’s Syndrome, are now included under the autism spectrum. This has contributed to the higher reported rates.


While the numbers have grown, the positive side is that early diagnosis and intervention, especially through Applied Behavior Analysis (ABA), can make a significant difference in a child’s development and quality of life.


At Steady Strides ABA, we provide personalized ABA therapy in Texas and New Mexico, helping children with autism thrive at every stage.

What Age Is Too Late for ABA Therapy?

By Jane Miller • November 13, 2025
It’s never too late to benefit from ABA therapy . While early intervention is highly effective, especially between 2 and 6 years old, ABA therapy can still provide significant improvements for older children, teens, and even adults.  The earlier therapy begins, the faster a child can develop essential skills like communication, social interaction, and behavior management. However, ABA therapy is effective at any age and can be tailored to meet the unique needs of individuals as they grow. For older children or adults, ABA can help with job readiness, independence, and socialization.
