Population Health Research Brief Series

Adults with intellectual and developmental disabilities (IDD) die younger than those without such disabilities in the U.S. This data slice introduces a new data tracking tool that shows age-at-death trends for adults with intellectual disability, Down syndrome, cerebral palsy, and other rare developmental disabilities, as well as those without IDD. The website, which will be updated annually, allows users to compare age-at-death patterns for each IDD group by U.S. state, year, biological sex, and race-ethnicity.
