CDC Study on Prevalence of Down Syndrome

The most recent study by the Centers for Disease Control and Prevention (CDC) and the National Birth Defects Prevention Network updates national statistics regarding the prevalence of Down syndrome in the U.S. 

The study indicates that there are about 6,000 diagnoses of Down syndrome each year in the United States. One in every 691 babies is born with Down syndrome. This is an increase from the previously reported statistic of 1 in every 733.

Based on the study, the National Down Syndrome Society (NDSS) cites this prevalence estimate on its website and other materials.
