California reports the highest prevalence of autism in the United States. In this webinar, Dr. Pierce — the California site Principal Investigator for the CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network — will take an in-depth look at the rising prevalence rates and what they truly mean. She will explore how evolving diagnostic criteria, shifting terminology, and a growing recognition of autism’s biological and clinical diversity have reshaped our understanding of the condition. The talk will review ADDM methodology and newest results, global prevalence trends, and research aimed at characterizing and understanding autism’s considerable heterogeneity. Dr. Pierce will also discuss why subtyping is essential for advancing science and services, and how emerging concepts such as “profound autism” fit into this evolving conversation.

Webinar Speaker Quote

"Autism is not a single, uniform condition but a spectrum of diverse biological and clinical profiles. As prevalence rates continue to rise, understanding how changing definitions, diagnostic practices, and recognition of heterogeneity shape those numbers is critical. Embracing that diversity is key to advancing science, care, and support."

Karen Pierce, Ph.D.

Professor, Department of Neurosciences,

University of California, San Diego
