According to the Center for Disease Control it is estimated that:
- One in every 88 children is diagnosed with autism, making it more common than childhood cancer, juvenile diabetes and pediatric AIDS combined.
- An estimated 1.5 million individuals in the U.S. and tens of millions worldwide are affected by autism.
- Government statistics suggest the prevalence rate of autism is increasing 10-17 percent annually. There is not established explanation for this increase, although improved diagnosis and environmental influences are two reasons often considered.
- Studies suggest boys are more likely than girls to develop autism and receive the diagnosis five times more frequently.
- Current estimates are that in the United States alone, one out of 54 boys is diagnosed with autism.
- If 4 million children are born in the United States every year, approximately 36,500 children will eventually be diagnosed with an ASD. Assuming the prevalence rate has been constant over the past two decades, we can estimate that about 730,000 individuals between the ages of 0 to 21 have an ASD.
- Studies in Asia, Europe and North America have identified individuals with an ASD with an approximate prevalence of 1%. A recent study in South Korea reported a prevalence of 2.6%.
- Costs of lifelong care are currently $137 billion annually and new estimates suggest a three-fold increase in less than a decade.
