The survey looks at indicators across five broad categories: electoral process and pluralism; civil liberties; the functioning of government; political participation; and political culture.

According to the survey, countries are divided into four types of regime: full democracies (28 countries), flawed democracies (54), hybrid regimes (30), and authoritarian regimes (55).

Only 13 percent of the world lives in full democracies, though almost half live in democracies of some sort. Sweden ranks as the fullest democracy, followed closely by Iceland and the Netherlands.

Most countries in the Commonwealth of Independent States (CIS) are either ranked as hybrid or authoritarian regimes. Among the CIS states, only Ukraine and Moldova attain the status of flawed democracies.

According to the survey, Russia is on a "watch list," due to concerns that it could slip from its hybrid status into an authoritarian regime.

Azerbaijan, Kazakhstan, Tajikistan, Turkmenistan, and Uzbekistan are already classified as authoritarian. Neighboring Kyrgyzstan is ranked as a hybrid regime.

The United States (17th place), the United Kingdom (23rd), and France (24th) are near the bottom of the list of full democracies due to erosions of civil liberties. North Korea ranks as the least democratic country in the index. RFE/RL
