Global Burden of Disease (GBD)

The GBD study is the largest and most comprehensive effort to quantify health loss across places and over time, so health systems can be improved and disparities eliminated.

607 billion+ Highly standardized and comprehensive estimates of health outcome and health system measures.
459 Health outcomes and risk factors, providing a powerful basis for insights on global health trends and challenges.
204 Countries and territories, plus dozens of sub-national locations show trends at regional, national, and local levels.
11,000+ Individuals from over 160 countries and territories collaborate in vetting GBD data sources and estimates.

Latest findings from GBD 2021

The latest capstone paper with data through 2021 shows a seismic shift in health trends due to the COVID-19 pandemic.

Life expectancy declined in 84% of countries and territories during the COVID-19 pandemic. 

Between 1950 and 2021, global life expectancy increased by almost 23 years from 49 to 71.7 years. But it declined by 1.6 years between 2019 and 2021.

By 2100, fertility rates will not be high enough to sustain population growth over time in 97% of countries and territories.

Researchers anticipate a massive shifting of births from high-income countries to low-income countries. Unless countries facilitate ethical immigration, populations are expected to contract in areas where fertility is below 2.1 children per person who could give birth.
