Statistics can help shed light on some of the current trends in autism. For example, according to the statistics on autism, males are four times more likely to have autism than females. While statistics indicate that more children are getting special education services for the disorder than ever before, it is unclear how much of this increase is due to changes in how autistic people are identified and classified.
Statistics On Autism: An OverviewExperts estimate that two to six children out of every 1,000 will have autism. Males are four times more likely to have autism than females.
Autism Statistics Compared to Other Childhood DisabilitiesA study conducted by the Centers for Disease Control and Prevention found the rate of autism for children ages 3 to 10 years to be 3.4 per 1,000 children, which is lower than the rate for mental retardation (9.7 per 1,000 children); but higher then the rates for cerebral palsy (2.8 per 1,000 children), hearing loss (1.1 per 1,000 children) and vision impairment (0.9 per 1,000 children) found in the same study.
- Mental retardation
- Cerebral palsy
- Hearing loss
- Vision impairment.
Of these serious developmental disabilities, mental retardation (or intellectual disability) is the most common. A genetic disorder often associated with having mental retardation (MR) or an intellectual disability (ID) that many people recognize is Down syndrome. Current information indicate that having Down syndrome occurs in 1 out of 800 births and is slightly less common than autism.
