Based on 2022 data from the CDC's Autism and Developmental Disabilities Monitoring (ADDM) Network, this represents a prevalence of approximately 3.2%.
Key Takeaways
- The overall prevalence of Autism Spectrum Disorder in South Dakota is estimated at 1.09%, which is lower than many other states.1.09%[7]
- South Dakota faces a significant shortage of specialized providers, with approximately 10 ABA providers per 100,000 children, compared to the national average of 15.10 vs 15[8]
- A notable gender disparity exists in South Dakota, where males are diagnosed with ASD at a rate of 1.50%, more than double the female rate of 0.69%.1.50% vs 0.69%[7]
- The lifetime cost to care for an individual with ASD in South Dakota is substantial, estimated to be between $1.4 million and $3.2 million.$1.4M - $3.2M[6]
- Nationally, a significant treatment gap persists, with 25% to 40% of individuals diagnosed with ASD not receiving services considered optimal for their needs.25-40%[3]
- ASD prevalence has risen dramatically over the past two decades, from 1 in 150 children in 2000 to 1 in 31 by 2022, largely due to improved awareness and diagnostic methods.1 in 150 → 1 in 31[4]
Understanding Autism Prevalence in South Dakota
Understanding the prevalence of Autism Spectrum Disorder (ASD) in South Dakota provides critical insights into the state's healthcare needs, resource allocation, and support systems for individuals and families affected by the condition. While national data offers a broad perspective, state-specific statistics reveal unique local challenges and trends, particularly in a predominantly rural state where access to diagnostic and therapeutic services can vary significantly. These figures are essential for policymakers, healthcare providers, and community organizations to develop targeted strategies that improve early diagnosis, intervention, and long-term support.

This emerging lifetime prevalence data suggests a broader adult population is affected than previously thought.
Demographic Disparities in ASD Diagnosis
Demographic factors such as gender and race play a significant role in the identification of Autism Spectrum Disorder. In South Dakota, as in the rest of the nation, boys are diagnosed with ASD far more frequently than girls[3]. This long-standing trend may be influenced by a combination of biological vulnerabilities and diagnostic criteria that have historically been based on male-typical presentations of the condition. The data below illustrates this significant gap within the state.

Access to Care and Treatment Services
Access to timely and effective services is paramount for improving outcomes for individuals with ASD. However, families in South Dakota face considerable challenges, including a shortage of specialized providers, long wait times for diagnosis and therapy, and geographic barriers inherent to a rural state[6]. The state's density of Applied Behavior Analysis (ABA) providers, a key intervention, is notably lower than the national benchmark, which directly impacts the availability of care for children in need.

The Economic Impact of Autism
The financial commitment required to support an individual with ASD throughout their life is substantial, encompassing costs for healthcare, special education, and adult care. In South Dakota, the estimated lifetime cost can range from $1.4 million to $3.2 million, depending on the individual's level of independence[6]. Recognizing this burden, the state has taken legislative steps to improve insurance coverage for essential therapies, providing critical financial relief to many families.
Financial Considerations
Since 2018, South Dakota legislation provides this coverage for children under age 19.
PubMed CentralNational Trends in ASD Prevalence
The prevalence of Autism Spectrum Disorder has shown a consistent and significant increase over the last two decades. This trend is largely attributed to a combination of factors, including expanded diagnostic criteria, greater awareness among healthcare professionals and the public, and improved screening methods[4]. While the numbers have risen, this reflects a better ability to identify and support individuals with ASD rather than a true epidemic. The chart below visualizes this dramatic shift in identification rates among children in the CDC's ADDM Network.
