Countries with the highest rates of autism among children worldwide as of 2018

In 2018, it was estimated that around 168 per 10,000 children in the United States had autism spectrum disorder, one of the highest prevalence rates in the world. Autism spectrum disorder (ASD) includes a variety of disorders. The “spectrum” denotes the range of symptoms as well as their severity. Symptoms can include difficulties with speech, social communication and interaction, repetitive behavior, sensory issues, and hypersensitivity to stimuli.

In the United States

Autism spectrum disorder is more common among boys than girls. In the U.S., around 3.63 percent of boys aged 3 to 17 years had autism spectrum disorder compared to 1.25 percent of girls. In the United States, autism spectrum disorder is more common among non-Hispanic white children than other ethnicities. According to the most recent available data, the Northeast region had the highest rate of autism spectrum disorder in the U.S., with around 3 percent.

Living with autism spectrum disorder

It is unclear what causes autism spectrum disorder and there is no cure. Therapy can help children with autism spectrum disorder develop social, communication and self-care skills that can help them better live with their disorder. Many children with autism spectrum disorder also suffer from other disorders such as attention deficit hyper activity disorder, a learning disability, or an intellectual disability.
