The Incidence of Autism Spectrum Disorder
The incidence of autism may be much higher than previously thought in the United States and elsewhere in the world, according to a recent rigorous, comprehensive study of the autism condition, conducted in South Korea. In the first ever attempt to take a broad-based look at an entire population for the prevalence of autism spectrum disorders – and all types of autism ranging from severe symptoms to the milder Asperger’s syndrome – researchers found a rate of 2.64% among South Korean children. That’s an incidence rate of 1 in 38 children, a rate far higher than the estimate of 1 in 110 children for the U.S., published by the Centers for Disease Control and Prevention (CDC).
