The Global Freedom Index measures a country's economic freedom, social freedom and civil liberties.
0-40 - the higher the score, the freer the country.
I made it by combining:
Freedom House's Freedom in the World Index (0-10)
Heritage Foundation's Index of Economic freedom (0-10)
My Social Freedom Index (0-10) http://chartsbin.com/view/40644
And Incarceration rate by country (0-10)
