Important studies show data of Autism. Here are 10 things you may not have known about Autism Spectrum Disorders (ASD):
- About 1 in 68 children (or 14.7 per 1,000 8 year olds) were identified with ASD.
- 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).
- 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).
- Boys were almost 5 times more likely to be identified with ASD than girls.
- White children were more likely to be identified with ASD than black or Hispanic children.
- Less than half (44%) of children identified with ASD were evaluated for developmental concerns by the time they were 3 years old.
- Most children identified with ASD were not diagnosed until after age 4, even though children can be diagnosed as early as age 2.
- Black and Hispanic children identified with ASD were more likely than white children to have intellectual disability.
- About 80% of children identified with ASD either received special education services for autism at school or had an ASD diagnosis from a clinician.
