2010 Utah ASD Administrative Prevalence Data


  1. Prevalence is  how commonly a condition occurs in a population.   
  2. The administrative ASD method to determine prevalence includes the rate of children with an existing ASD classification from a school or health provider.



    Total prevalence of ASDs

              4 year olds: 9.2 per 1,000 (1 in 108)

              6 year olds: 13.7 per 1,000 (1 in 73)

              8 year olds: 15.8 per 1,000 (1 in 63)

  • Utah rates of ASDs are among the highest in the nation and nearly double the national average.
  • Utah boys are nearly four times more likely than girls to have an administrative prevalence of an ASD.
  • Lower rates of ASD among older children may be attributed to delays in early detection, difficulty in obtaining an ASD diagnosis and lack of access to services.
  • Reasons for increases in the rate of ASD are unknown but may be related to: improvements in screening, diagnosis, and treatment; greater awareness of the condition; and/or improved documentation.
  • Economic costs of ASD are substantial. Medical expenditures per year for individuals with ASD are substantially higher than those without ASDs.
