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.The cornerstones of economic freedom are personal choice, voluntary exchange,freedom to enter markets and compete, and security of the person and privately owned property. Forty-two data points are used to construct a summary index, along with a Gender Legal Rights Adjustment to measure the extent to which women have the same level of economic freedom as men. This is the same structure as last year, though changes have been made to nine of the components.The degree of economic freedom is measured in five broad areas.

Area 1: Size of Government

As government spending, taxation, and the size of government-controlled enterprises increase, government decision-making is substituted for individual choice and economic freedom is reduced.

Area 2: Legal System and Property Rights

Protection of persons and their rightfully acquired property is a central element of both economic freedom and civil society. Indeed, it is the most important function of government.

Area 3: Sound Money

Inflation erodes the value of rightfully earned wages and savings. Sound money is thus essential to protect property rights. When inflation is not only high but also volatile, it becomes difficult for individuals to plan for the future and thus use economic freedom effectively.

Area 4: Freedom to Trade Internationally

Freedom to exchange—in its broadest sense, buying, selling, making contracts,and so on—is essential to economic freedom, which is reduced when freedom to exchange does not include businesses and individuals in other nations.

Area 5: Regulation

Governments not only use a number of tools to limit the right to exchange internationally,they may also impose onerous regulations that limit the right to exchange,gain credit, hire or work for whom you wish, or freely operate your business.
