The 2018 Index of Economic Freedom relies on data from multiple internationally recognized sources to present a representation of economic freedom in each country that is as comprehensive, impartial, and accurate as possible. The following sources provided the primary information for analyzing and scoring the 12 components of economic freedom. In addition, the authors and analysts used supporting documentation and information from various government agencies and sites on the Internet, news reports and journal articles, and official responses to inquiries. All statistical and other information received from government sources was verified with independent, credible third-party sources.
