“Changes in Prevalence of Parent-Reported Autism Spectrum Disorder in School-Aged Children: 2007 to 2011-2012.”
The report was co-authored by HRSA and data collection was conducted by the CDC. The data come from the National Survey of Children’s Health, a nationally representative phone survey of households with children. This survey is conducted every four years.
Main findings of the report:
- The prevalence of parent-reported ASD among children aged 6-17 years was 2 percent in 2011-2012 compared to 1.2 percent in 2007.
- The change in prevalence estimates was greatest for boys and for adolescents aged 14 to 17 years.
- Children who were first diagnosed in or after 2008 were more likely to have milder ASD than those diagnosed in or before 2007.
- Much of the increase in the prevalence estimates from 2007 to 2011-2012 for school-aged children was the result of diagnoses of children with previously unrecognized ASD.
The report is available at www.cdc.gov/nchs.
