How many boys have autism
This is a 10 percent increase from the most recent report two years ago when it was 1 in 59, and the highest prevalence since the CDC began tracking ASD in Consistent with previous reports, boys were 4 to 5 times more likely to be identified with ASD than girls. The rate for ASD is 1 in 34 among boys or 2. ASD is a developmental disorder characterized by social and communication impairments, along with limited interests and repetitive behaviors.
Early diagnosis and intervention are key to improving learning, communication, and other skills. Technical factors that may be contributing to an increase in ASD include increased awareness, screening, diagnostic services, treatment and intervention services, better documentation of ASD behaviors, and changes in diagnostic criteria.

Between four and five times as many boys as girls are diagnosed with ASD each year, and the same has been true for as far back as there are records. Through the modern surge in diagnoses and the intensive investigations into this phenomenon that followed, that ratio has remained relatively static. Why are boys apparently more susceptible to ASD?
But recent research has begun to open up some hypotheses about the issue that might shed light on both autism and on some of the basic and ancient differences between the male and the female brain.
Today, as gender identity and equality have become loaded political questions, such a statement would immediately draw fire. Many individuals diagnosed with autism may, in the past, have been misdiagnosed with other conditions, such as intellectual disability: As diagnoses of autism have risen, those of intellectual disability have decreased.
This benefit makes clinicians more likely to diagnose a child with autism, even those who are on the borderline of the clinical criteria.
Prior versions of the DSM did not allow for children to be diagnosed with both autism and attention deficit hyperactivity disorder. The DSM-5 allows multiple diagnoses, and most children with developmental delay are routinely screened for autism. Autism prevalence has traditionally been highest in white children in the U. S, but this is starting to change. African-American and Hispanic children have lower rates of diagnosis because of a lack of access to services.
Widespread screening has improved detection of autism in these groups, and raised overall prevalence. Is there no real increase in autism rates, then? Awareness and changing criteria probably account for the bulk of the rise in prevalence, but biological factors might also contribute, says Durkin. For example, having older parents, particularly an older father , may boost the risk of autism. Children born prematurely also are at increased risk of autism, and more premature infants survive now than ever before.
