Economic Freedom of the World Data System
In addition to the Fraser Institute Economic Freedom dataset, the Economic Freedom of the World index data has been incorporated in a software tool which you can also use to search, filter, and export from. This data system also contains the complete database of the World Bank Development Indicators, so correlations can be drawn between economic freedom and economic outcomes such as health, wealth, literacy and many more.
Human Progress.org, a project of the Cato Institute, explores the state of humanity with data, charts, & maps. All of the wide-ranging data comes from third parties, including the World Bank, the OECD, the Eurostat, and the United Nations.
