The report uses data from the National Survey of Children&#8217;s Health, which was based on reporting by parents of school-aged children (ages 6\u201317 years) in 2011\u20132012, and compared with earlier data from the NSCH in 2007.  The survey was funded by the Health Resources and Services Administration&#8217;s  Maternal and Child Health Bureau.  The increase from 2007 to 2011\u20132012 was evaluated using cohort analyses that examine the consistency in the 2007 and 2011\u20132012 estimates for children whose diagnoses could have been reported in both surveys.<\/p>\n<p>ASD is\u00a0a set of complex neurodevelopment\u00a0disorders that include autistic disorder,\u00a0Asperger disorder, and pervasive\u00a0developmental disorder not otherwise\u00a0specified.

This prevalence\u00a0estimate (1 in 50) is significantly higher\u00a0than the estimate (1.16%, or 1 in 86) for\u00a0children in that age group in 2007. \u00a0The magnitude of the increase was greatest for boys and for adolescents aged 14\u201317. \u00a0Cohort analyses revealed consistent estimates of both the prevalence of parent-reported ASD and autism severity ratings over time. \u00a0Children who were first diagnosed in or after 2008 accounted for much of the observed prevalence increase among school-aged children (those aged 6\u201317). 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.<\/p>\n<p><a href=\"http:\/\/nchspressroom.files.wordpress.com\/2013\/03\/autism-chart.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-1413 alignleft\" alt=\"Percentage of children aged 6\u201317 years with parent-reported autism spectrum disorder, by age group and sex: United States, 2007 and 2011\u20132012\" src=\"http:\/\/nchspressroom.files.wordpress.com\/2013\/03\/autism-chart.jpg?w=450\" width=\"450\" height=\"260\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Nearly one million school-aged children in the U.S. have autism spectrum disorder (ASD), according to a new NCHS report released today.
