(CDC release) A recent government survey released by the Centers for Disease Control & Prevent estimates that 1 in 50 children has been identified with an autism spectrum disorder (ASD).
According to the CDC, the report presents data collected & reported by parents of school-aged children (ages 6-17 years) in 2011-2012. Data was collected from the 2007 and 2011-2012 National Survey of Children's Health (NSCH), which independently made telephone surveys of households with children.
The results show the prevalence of parent-reported ASD among children aged 6-17 was 2.00% in 2011-2012, a significant increase from 2007 (1.16%). The magnitude of the increase was greatest for boys and for adolescents aged 14-17. Cohort analyses revealed consistent estimates of both the prevalence of parent-reported ASD and autism severity ratings over time. Children who were first diagnosed in or after 2008 accounted for much of the observed prevalence increase among school-aged children (those aged 6-17). School-aged children diagnosed in or after 2008 were more likely to have milder ASD and less likely to have severe ASD than those diagnosed in or before 2007.
Like the many families living with ASDs, CDC considers ASDs an important public health concern. CDC is committed to continuing to provide essential data on ASDs, search for risk factors and causes, and develop resources that help identify children with ASDs as early as possible.
