    Community ReportBased on tracking in five ADDM Network sites across the United States, about 1 in every 75 preschool-aged children was classified as having an ASD. This estimate among 4-year-olds is about 30% lower than the prevalence among 8-year-olds.  The reason for this may be due to later evaluation and diagnosis as it is often not until a child faces the challenges of school that developmental issues come to light.
