Autism is prevalent across the world, although tracking rates can vary due to differences in reporting. In 2021, the Centers for Disease Control and Prevention (CDC) issued its Autism prevalence report.
- The report concluded that the prevalence of Autism had risen to 1 in every 44 – more than twice as great as the 2004 rate of 1 in 125.
- Children who receive an Autism diagnosis by age 4, are fifty times more likely to receive services.
- The 2021 report noted that more White and Black children were identified with Autism than Hispanic children.
- The 2020 report was the first to indicate that, on average, White and Black children were equally as likely to have a diagnosis by the age of 8 years, in the sample studied by the CDC.
- Previous studies have shown, that children of color may still receive their diagnoses later than White children. Stigma, lack of access to healthcare services due to non-citizenship or low-income, and non-English primary language are potential barriers to the early identification of Hispanic children and children of color with Autism.
- Currently, boys are also approximately 4 times more likely to have an Autism diagnosis than girls of the same age.
- However, recent research suggests that girls may not display characteristics of Autism in the same way as boys and might go undiagnosed because of their different presentation.

As noted previously, determining eligibility for special education under the autism disability category requires that the criteria established in the Nebraska Department of Education's Rule 51 are met. A medical diagnosis of autism spectrum is based upon criteria established in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5). DSM-5 includes a new system of determining severity see chart below. For more information regarding the DSM-5 diagnostic criteria please visit here
