Is autism more common in boys than girls? Yes—current research shows boys are about four times more likely to be diagnosed with autism than girls.
Key Statistics
For every four boys diagnosed with autism, only one girl receives the same diagnosis.
In the U.S., about 4 in 100 boys and 1 in 100 girls have autism.
The CDC reports that autism is over three times more common in boys than girls.
Why the Difference?
Girls with autism often have subtler symptoms and may “mask” their behaviors, making diagnosis harder.
Some studies suggest girls need more genetic changes to develop autism, and diagnostic criteria may be based more on how autism appears in boys.
New research hints that the true ratio may be closer to 3:1, as more girls are identified with autism over time.
At Blossom ABA Therapy, our team has seen more boys than girls referred for autism assessment and therapy. However, parents of girls often share stories about late or missed diagnoses, highlighting the need for careful, individualized evaluation.
