evidence: The Global Health Expenditure Database (GHED) provides comparable data on health expenditure for more than 190 WHO Member States since 2000 with open access to the public. Health spending indicators are key guides for monitoring the flow of resources, informing health policy development, and promoting the transparency and accountability of health systems. The database can help answer questions such as how much countries spend on health, how much of the health spending comes from government, households, and donors, and how much of the spending is channelled through compulsory and voluntary health financing arrangements. The database also includes a detailed breakdown of spending for an increasing number of countries on health care functions and primary health care, spending by diseases and conditions, spending for the under 5-year-old population, and spending by provider type.
