The Global Burden of Disease Study 2021 (GBD 2021), coordinated by the Institute for Health Metrics and Evaluation (IHME), estimated the burden of diseases, injuries, and risk factors for 16 European Economic Area (EEA) countries (Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden) and the United Kingdom (England, Northern Ireland, Scotland, Wales). This dataset includes estimates for life expectancy decomposition for 1990-2021. Data sources used to produce the estimates came from GBD 2021. Other estimates used to support this analysis (life expectancy (LE), summary exposure values (SEV), and population) can be accessed in the GBD 2021 Results Tool.
