Only four countries in the world today do not identify themseves as democratic in one form or another. These are Saudi Arabia, Myanmar (Burma), Brunei, and Vatican City.

Of the other countries there are many that claim to be democratic, but in practice are too corrupt, too volatile, or have too many restrictions on human rights to be considered "true democracies"

According to the Democracy Index produced by the Economist Magazine there are

30 Full Democracies: Where national elections are free and fair, voters are free to vote in safety, there is no manipulative influence by foreign governments, and the civil cervice is capable of administering polices effectively.

50 Flawed Democracies: Countries that practice democracy, but have some significant problems with the process.

36 Hybrid Regimes: Where there is some democratic elements but they are often hampered by corruption or threat as to be less effective than they might otherwise.

51 Authoritarian Regimes: Where the state claims to be democratic but in practice there is little or no democracy in the process or running the nation.

The "Full Democracies" according to the Democracy index are:

Sweden, Norway, Iceland, Netherlands, Denmark, Finland, New Zealand, Switzerland, Luxembourg, Australia, Canada, Ireland, Germany, Austria, Spain, Malta, Japan, United States, Czech Republic, Belgium, United Kingdom, Greece, Uruguay, France, Portugal, Mauritius, Costa Rica, South Korea, Italy, and Slovenia
