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

Yes, autism is more commonly diagnosed today than 20 years ago. In 2000, the CDC estimated about 1 in 150 children had Autism Spectrum Disorder (ASD). By 2022, this rose dramatically to 1 in 31 children. This increase is linked to broader diagnostic criteria, heightened awareness, and better screening rather than a sudden jump in autism itself.

Studies show a nearly 787% rise in autism diagnoses in some places over the last two decades, with notable increases in diagnosis rates among adults and females, indicating better recognition of autism across diverse groups. The growing number of identified cases means more children and adults receive support early on, improving lives.

Though it may seem like autism is an epidemic, experts agree the rise primarily reflects improved detection and understanding of the spectrum. If concerns arise about developmental delays or social challenges, scheduling an assessment with Achieve Behavioral Therapy can provide clarity and personalized support plans.
