CountryData offers political, economic, financial, and social data for over 140 countries, in most cases back to 1984. CountryData is also the only source for current and historical risk ratings developed from the International Country Risk Guide and Political Risk Services rating systems conducted by PRS Group. Note: the tabs International Country Risk Guide (ICRG) and Political Risk Services (PRS) provide access to information regarding methodology, but do not provide access to the actual products. Access to the CountryData and the Political Risk Yearbook are available through the University Libraries A-Z list.
