how many kids have autism

Around the world, the best current estimates suggest that roughly 1 in 100 children are diagnosed with autism spectrum disorder (ASD), which is about 1% of all children globally.

In the United States, more detailed surveillance indicates that about 1 in 36 children has an autism diagnosis, which is around 2.8% of U.S. children and higher than the global average.

Because global data are incomplete and many countries underdiagnose or underreport autism, these figures are estimates , not exact counts, but they reflect the current consensus of large public‑health and research organizations.
