Freedom in the World was launched in 1973 by Raymond Gastil. It produces annual scores representing the levels of political rights and civil liberties in each state and territory, on a scale from 1 (most free) to 7 (least free). Depending on the ratings, the nations are then classified as "Free", "Partly Free", or "Not Free".[4] The report is often used by researchers in order to measure democracy and correlates highly with several other measures of democracy such as the Polity data series.[5]
