#who

The World Health Organization's Global Health Observatory (GHO) as an API — authoritative global health statistics for every WHO member state. Search a catalogue of more than 3,000 health indicators spanning life expectancy and healthy life expectancy, mortality and causes of death, immunization and vaccine coverage, communicable and noncommunicable disease burden, maternal and child health, nutrition, mental health, health workforce, health financing, water and sanitation, and risk factors such as tobacco, alcohol and obesity. For any indicator, pull a country's complete time-series — each data point with its year, value, the WHO uncertainty interval (low and high bounds), the WHO region and the breakdown dimension (for example sex) — or compare the indicator across many countries for a chosen year, or the latest available year per country, ranked by value. Country codes are ISO3 (DEU, USA, JPN) or WHO region codes; results can be filtered by sex (both, male or female). Ideal for public-health research, journalism, NGO and policy dashboards, epidemiology and global-development analysis. Indicator codes come from the indicators endpoint (e.g. WHOSIS_000001 is life expectancy at birth). Data from the WHO Global Health Observatory.
