Autism’s rise tracks with drop in other childhood disorders
The latest estimate of autism prevalence in the U.S., released last week, suggests the condition is even more common than previously thought. But the apparent rise in autism coincides with a decline in other developmental disorders, highlighting the complexity folded into this seemingly simple statistic.
The U.S. Centers for Disease Control and Prevention (CDC) estimates that 1 in 45 children have autism, up from 1 in 80 in 20131. The new figure is based on the annual door-to-door National Health Interview Survey, which asks parents whether a doctor has ever told them their child has autism, intellectual disability or another type of developmental delay.
