According to the U.S. Centers for Disease Control and Prevention, an estimated one in 110 children in the United States has an autism spectrum disorder, part of a group of developmental disabilities that can cause significant social, communication and behavioral challenges.

The Harris Interactive/HealthDay poll was conducted online within the United States from Jan. 11-13, and included 2,026 adults over the age of 18. Figures for age, sex, race/ethnicity, education, region and household income were weighted where necessary to bring them into line with their actual proportions in the population.
