In 2014 the Centers for Disease Control (CDC) released data on an autism surveillance study.
- The new data estimated the prevalence of autism spectrum disorders (ASD) as 1 in 68 among eight-year children within multiple communities of the United States.
- The new figure was about 30% higher than the previous estimate they reported in 2012 and approximately 120% higher than the estimates for 2002. This provides for a rough 6-15% increase each year during the last decade.
- The overall ASD prevalence in South Carolina has matched the steep increase in national numbers. Review the CDC Fact Sheet.
- 6.3/1000 in the 2000 birth cohort to 11.1/1000 in the 2008 cohort. This is a 76% increase in eight years. Boys are consistently found to have a higher prevalence rate than girls, 4-5:1.
- According to the 2013 South Carolina Census and considering only individuals under 18 years of age, there are approximately over 16,000 people who would fit the diagnosis of ASD within our state.
