To understand why healthspan has not kept up with increases in lifespan, longevity researchers need to know what exactly is making people chronically ill or disabled. The Institute for Health Metrics and Evaluation, a research organization at the University of Washington, has compiled data on people living with diseases and conditions that affect their health—a metric researchers call “years lived with disability.” As a population ages, these conditions pose a heavier burden.
These are the top contributors to years lived with disability in the U.S.:
These diseases contribute differently to disability at different life stages:
The bars show years lost to disability in the U.S., grouped into 5-year bins. To allow easier comparisons between those age bins, the data are displayed as disease occurrence per 100,000 people.
