Developmental disabilities occur among all
racial, ethnic, and socioeconomic groups. Recent
estimates in the United States show that about
one in six, or about 17%, of children aged 3
through 17 years have one or more
developmental disabilities, such as:
– ADHD,
– autism spectrum disorder,
– cerebral palsy,
– hearing loss,
– intellectual disability,
– learning disability,
– vision impairment,
– and other developmental delays.
