Global Burden of Disease (GBD)Purpose: "To provide policymakers, researchers, donors, and other decision-makers with the most timely and up-to-date picture of population health to inform critical decisions, the Global Burden of Disease (GBD) will produce annual updates to its estimates. The first update, GBD 2013, uses and expands upon the infrastructure of methodology, datasets, and tools that were presented in GBD 2010, and presents estimates of all-cause mortality, deaths by cause, years of life lost, years lived with disability, and disability-adjusted life years by country, age, and sex."
