Drawing from officially recognized sources and including national, regional, and global estimates, the WDI provides access to approximately 1,600 indicators for 217 economies, with some time series extending back more than 50 years.
[1] The topics covered in the WDI range from poverty, health, and demographics to GDP, trade, and the environment.
A share of the indicators in WDI come from World Bank Group surveys and data collection efforts, but the majority are based on data originally collected, compiled and published by other sources, including other international organizations such as UN specialized agencies (sometimes in cooperation with the World Bank), national statistical offices, organizations with a specific research or monitoring focus, the private sector, and academic studies.
The World Bank’s Open Data site provides access to the WDI database free of charge to all users.
The WDI database can be accessed directly via DataBank, a query tool where users can select series, economies, and time periods, and do bulk downloads in Excel or CSV, or via API.
