Inessa [10]

Answer:

# 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.
