WHO’s Global Health Estimates present comprehensive and comparable time-series data from 2000 onwards for health-related indicators, including life expectancy, healthy life expectancy, mortality and morbidity, as well as burden of diseases at global, regional and country levels, disaggregated by age, sex and cause. They are produced using data from multiple consolidated sources, including national vital registration data, latest estimates from WHO technical programmes, United Nations partners and inter-agency groups, as well as the Global Burden of Disease and other scientific studies. A broad spectrum of robust and  well-established scientific methods were applied for the processing, synthesis and analysis of data.
