10 Things You Need To Know About CDC's Latest Report from the Autism and Developmental Disabilities Monitoring Network
The following estimates are based on information collected from the health and special education (if available*) records of children who were 8 years old and lived in areas of Alabama, Arizona, Arkansas, Colorado, Georgia, Maryland, Missouri, New Jersey, North Carolina, Utah, and Wisconsin in 2010:
- About 1 in 68 children (or 14.7 per 1,000 8 year olds) were identified with ASD. It is important to remember that this estimate is based on 8-year-old children living in 11 communities. It does not represent the entire population of children in the United States.
- This new estimate is roughly 30% higher than the estimate for 2008 (1 in 88), roughly 60% higher than the estimate for 2006 (1 in 110), and roughly 120% higher than the estimates for 2002 and 2000 (1 in 150). We don't know what is causing this increase. Some of it may be due to the way children are identified, diagnosed, and served in their local communities, but exactly how much is unknown.
- The number of children identified with ASD varied widely by community, from 1 in 175 children in areas of Alabama to 1 in 45 children in areas of New Jersey.
- Almost half (46%) of children identified with ASD had average or above average intellectual ability (IQ greater than 85).
