Now there’s a new study from the Center for Autism and Related Disorders at Kennedy Krieger Institute. The study found that “64 percent of children with an autism spectrum disorder (ASD) belong to a family with two married biological or adoptive parents, compared with 65 percent of children who do not have an ASD.” The study used a sample size of over 77,000 children. The review article doesn’t specify exactly how many of these 77,000 children were dealing with autism, but at a standard rate of 1 in 100 children, we could expect this study represents about 770 children on the spectrum.
Also, thanks to GRASP for mentioning this study in their monthly newsletter. Every month they publish an array of interesting articles related to autism and Asperger's.
