Question

Is autism more common in a certain group of people?

Answer 1

yes

Step-by-step explanation:

• About 1 percent of the world population has autism spectrum disorder.

• Prevalence in the United States is estimated at 1 in 54 births.

• More than 3.5 million Americans live with an autism spectrum disorder.

• Prevalence of autism in U.S. children increased by 119.4 percent from 2000 (1 in 150) to 2010 (1 in 68). Autism is the fastest-growing developmental disability.

• Prevalence has increased by 6-15 percent each year from 2002 to 2010. (Based on biennial numbers from the CDC)

• About 1 in 54 children has been identified with autism spectrum disorder (ASD) according to estimates from CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network.

• ASD is reported to occur in all racial, ethnic, and socioeconomic groups.

• ASD is more than 4 times more common among boys than among girls

• About 1 in 6 (17%) children aged 3–17 years were diagnosed with a developmental disability, as reported by parents, during a study period of 2009-2017. These included autism, attention-deficit/hyperactivity disorder, blindness, and cerebral palsy, among others.

Answer 2

Step-by-step explanation:

# Boys are four times more likely to be diagnosed with autism than girls.

# Most children were still being diagnosed after age 4, though autism can be reliably diagnosed as early as age 2.

# 31% of children with ASD have an intellectual disability (intelligence quotient [IQ] <70), 25% are in the borderline range (IQ 71–85), and 44% have IQ scores in the average to above average range (i.e., IQ >85).

# Autism affects all ethnic and socioeconomic groups.

# Minority groups tend to be diagnosed later and less often.

# Early intervention affords the best opportunity to support healthy development and deliver benefits across the lifespan.

# There is no medical detection for autism.
