In the USA, what fraction of children have developmental disabilities (DD)?

The correct answer is based on current estimates which indicate that approximately 1 in 6 children in the United States are diagnosed with developmental disabilities. This statistic reflects a broad range of developmental disorders, including but not limited to autism, intellectual disabilities, learning disabilities, and other related conditions. Understanding this fraction is essential for genetic counselors, as it underscores the prevalence of these conditions and the need for awareness and resources dedicated to supporting affected families.

The choice of 1 in 6 is representative of data gathered from various health organizations and public health surveys, which consistently report similar figures in studies concerning children’s health and development. Recognizing this prevalence informs practice in genetic counseling, as it can aid in counseling families regarding risks, available support services, and the importance of early intervention.

The other options, while they may reflect other statistics or perceptions, do not align with this current understanding and data regarding developmental disabilities in the child population.
