2010 Utah ASD Administrative Prevalence Data
- Prevalence is how commonly a condition occurs in a population.
- 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.
