"Results of a new survey show that in 2007, 673,000 children in the United States — or 1.1% of those aged 3 to 17 years — had autism spectrum disorder (ASD), up from previous prevalence estimates.  The new report shows that boys are about 4 times more likely to have ASD than girls, and the odds of having this condition are greater among white children.  The figures, based on data from the 2007 National Survey of Children's Health conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics, were published online October 5 in Pediatrics."
