…we use indicators that are as consistent as possible with the concept of negative liberty: the absence of coercive constraint on the individual. We do not attempt to measure positive freedom…nor do we measure so-called “claim freedoms,” which often become government-imposed attempts at realizing positive freedoms (e.g., the “right” or freedom to a have job or housing). …This index of freedom also does not incorporate measures of democracy or “political freedom.” …Democracy may be more consistent than other forms of government at safeguarding freedom, but it is not freedom, nor does it necessarily guarantee freedom. …We combine economic freedom measures from the Economic Freedom of the World (EFW) index with measures of what we somewhat imprecisely call civil or personal freedoms. The economic freedom index and the personal freedom index we devise each receive half the weight in the overall index.
For the personal freedom sub-index, we use 34 variables covering 123 countries… The index is divided into four categories: 1) Security and Safety; 2) Freedom of Movement; 3) Freedom of Expression; and 4) Relationship Freedoms. …We have tried to capture the degree to which people are free to enjoy the major civil liberties—freedom of speech, religion, and association and assembly—in each country in our survey. In addition, we include indicators of crime and violence, freedom of movement, and legal discrimination against homosexuals.
