While the rate of diagnosis for autism spectrum disorders (ASD) is the same among all racial groups, black kids tend to get diagnosed later than white children and receive longer and more intensive interventions, according to a study published in the journal Social Work in Public Health and reported by Newswise.

Autism is a general term for a spectrum of developmental disorders that affect a child’s social and communication skills. Children with autistic conditions, such as Asperger’s syndrome, have difficulty talking with others, interacting socially and in personal relationships and controlling repetitive behaviors. Currently, rates of diagnosis hover around one in 110 for children of all races. But when children are diagnosed varies dramatically.
