World Country Groups

This site provides an interactive reference for international country groups and organizations. It draws on the worldcountrygroups open-data package, which defines 117 country groups covering 232 countries and territories.

Each group includes member country lists with ISO 3166-1 codes. Aggregate statistics (GDP, population, CO2 emissions, and more) are sourced from the World Bank Open Data API, REST Countries, and UNDP Human Development Reports.
