World Freedom Atlas
The World Freedom Atlas is a “geovisualization tool” for world statistics. The amount of information is impressive - Peter Klein went into the trouble of linking to some of the sources:
It includes the most important variables used by economists including income and purchasing power from the Penn World Table, legal origin from LLSV, economic freedom from the Fraser Institute and the Heritage Foundation, policy constraints from Witold Henisz, the World Bank’s governance indicators, and a host of other variables from Acemoglu, Johnson and Robinson; Barro and Lee; Easterly and Levine; Persson and Tabellini; and several others.
