Data compiled by the Centers for Disease Control and Prevention indicates an alarming and continuing increase in the prevalence of autism. According to the latest survey, among 14 different sites on the Autism and Developmental Disabilities Monitoring (ADDM) Network, the estimated prevalence for autism spectrum disorders (DSM IV-TR) was 11.3 per 1,000 (one in 88) children aged 8 years of age who were living within these communities during 2008. This translates to approximately one in 54 boys and one in 252 girls living in the ADDM Network, a 78 % increase compared to the prevalence reported one decade ago.
