I’m not a fan of the Heritage Foundation, and the one time I dug into the data of their Economic Freedom Index I found that they occasionally compare apples and oranges to get around data scarcity – BUT: they do put a large research effort into the report each year. The below interactive map is well executed – but you should drill down to country level data to get a feel for what is really being measured (click on a country, then the “learn more about this country” link that pops up in the lower left. Why this requires two steps I have no idea).
