There are several non-governmental organizations that publish and maintain assessments of the state of freedom in the world, according to their own various definitions of the term, and rank countries as being free, partly free, or unfree using various measures of freedom, including political rights, economic rights, and civil liberties. The Economist Intelligence Unit's Democracy Index is an assessment of countries' democracy. Countries are rated to be either Full Democracies, Flawed Democracies, Hybrid Regimes, or Authoritarian. Full democracies, flawed democracies, and hybrid regimes are considered to be democracies, and the authoritarian nations are considered to be dictatorial. The Economist bases its ratings based on: civil liberties, conduct of elections, media freedom, participation, public opinion, functioning government, corruption, and stability.
