Age-at-death disparities between adults with and without intellectual and developmental disabilities (IDD) in the U.S. have historically varied by type of IDD. To improve our understanding of this persistent disparity, we constructed a website dedicated to tracking 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, currently allows users to compare age-at-death patterns for each IDD group by U.S. state, year, biological sex, and race-ethnicity for 2008-2017.
