Freedom House is an advocacy organization that monitors and supports the expansion of freedom around the world. The organization has developed a survey to measure and rate worldwide political rights and civil liberties. A rating of 1 indicates the highest degree of freedom and 7 the least amount of freedom. The political rights and civil liberties ratings for each country or territory are combined and averaged to determine an overall "freedom status." Countries and territories with a combined average rating of 1.0 to 2.5 are considered "Free"; 3.0 to 5.0, "Partly Free"; and 5.5 to 7.0 "Not Free". Upward or downward trend arrows may be assigned to countries and territories. Trend arrows indicate general positive or negative trends since the previous survey that are not necessarily reflected in the raw points and do not warrant a ratings change.
