Figure 2. Comparison of Prevalence Estimates.
The graph shows a comparison of previously reported Autism and Developmental Disabilities Monitoring (ADDM) Network autism spectrum disorder (ASD) prevalence estimates (2000–2008 surveillance years) to prevalence using DSM-5 ASD criteria (2006–2008 surveillance years). The population size (or geographic area) for some ADDM Network sites varied from year to year. The data collection methods for the 2002 and 2004 surveillance years are not compatible with the application of DSM-5 criteria. The line with diamonds indicates previously reported ADDM Network ASD prevalence estimates based on DSM-IV-TR criteria. The line with circles shows the prevalence of children meeting DSM-5 ASD criteria. The shaded area shows the prevalence of children who are not currently meeting ADDM Network ASD case status but may meet ASD case status using DSM-5 criteria. The error bars indicate 95% CIs.
