Utah Registry of Autism and Developmental Disabilities

Welcome to the Utah Registry of Autism and Developmental Disabilities' (URADD) website. We collect information about the number of individuals in Utah who have autism spectrum disorder (ASD) and other developmental disabilities (DD). Changes in ASD prevalence are studied in specific places and populations over time.

URADD was established in 2002 as a joint effort between the Utah Department of Health (UDOH) and the University of Utah Department of Psychiatry (Psychiatry); UDOH contracts with Psychiatry to conduct URADD. URADD uses a passive, population-based surveillance system in which individuals with ASD are identified based on a community medical diagnosis of ASD and/or an autism special education eligibility.


By studying the prevalence of ASD and other developmental disabilities (DD) in Utah over time, we are gathering important information that is used to:

  • Inform public policy decisions
  • Increase community awareness
  • Study the causes of ASD
  • Decrease the age at first identification of ASD
  • Plan for ASD related services
