The index published in Economic Freedom of the World measures the degree to which the policies and institutions of countries are supportive of economic freedom. In 2016, the latest year included in the analysis, Hong Kong and Singapore, as usual, occupy the top two positions. The next highest scoring nations are New Zealand, Switzerland, Ireland, United States, Georgia, Mauritius, United Kingdom, Australia, and Canada, the latter two tied for 10th spot. It is worth noting that the United States returned to the top 10 in 2016 after an absence of several years. Canada also returned to the top 10 after coming in 11th in 2015. The Czech Republic ranks 30th.
