Why Are Autism Rates Increasing in Children?  

One of the report’s lead authors, Dr. Zachary Warren, put it bluntly, “The most compelling finding is how incredibly common the presentation of autism is.” According to the CDC report, this increase reflects advances in:  

• Early Detection: More and more children receive evaluation before age 4. In fact, those born in 2018 are 1.7 times more likely to have been diagnosed before 48 months compared to those born in 2014.  

• Access to Educational and Health Services: Improved special education and public health systems have made it easier to identify more children on the spectrum.  

• Public Awareness: Parents, teachers, and pediatricians are more attentive to the signs of ASD.  

Key Facts About ASD Prevalence  

According to the CDC’s 2025 report:  

• The prevalence of autism in 8-year-olds is 32.2 per 1,000  
• Autism remains 3.4 times more common in boys than in girls  
• Rates of autism in children vary widely by region: for example, California reported the highest rate (53.1 per 1,000 children), while Texas (Laredo) had the lowest (9.7 per 1,000). This disparity reinforces the need for local strategies to reduce barriers to diagnosis and treatment.  
• Medical providers have improved identification among historically underserved populations. For example, Asian, Black, and Hispanic children now have higher rates of diagnosis than white children, which may reflect a decrease in social and cultural barriers to access.   
• 39.6% of children with autism also have an intellectual disability  
• 47% of diagnoses occur before the age of 4, which allows access to more effective early intervention.  

This data underscores the urgent need for equitable support services, early diagnosis, and access to specialized therapies such as ABA therapy. 

Autism Prevalence 2025: What Does This Mean for Our Community?  

This increase in autism rates should not generate fear but action. Identifying ASD at an early age allows access to therapies and supports that are critical to each child’s development. Among these, experts consider ABA therapy as the gold standard, as it is tailored to individual needs and promotes autonomy and social skills.  

At ABA Centers of America, we work with families in Massachusetts, New Hampshire, and across the United States to provide diagnosis, early intervention, home—and school-based ABA therapy, and ongoing support. We understand that each child is unique, so we design individualized plans tailored to their strengths and challenges.  

What Can We Do About the Increasing Prevalence of ASD? 

• Promote early evaluations, especially if you observe signs such as speech delay, lack of eye contact, or repetitive behaviors.  
• Access specialized services, such as ABA therapy, as early as possible.  
• Get informed and educated. Community awareness is a powerful tool for inclusion.  
• Don’t fall for myths. Science has proven that vaccines do not cause autism. The increase in diagnoses is not a crisis; it reflects progress in public health.
