English: The Democracy Index is an index compiled by the Economist Intelligence Unit (a private business) that measures the state of democracy in 167 countries, of which 166 are sovereign states and 165 are UN member states. The Economist Intelligence Unit's Democracy Index is based on 60 indicators grouped in five different categories: electoral process and pluralism, civil liberties, functioning of government, political participation and political culture. The Index was first produced in 2006, with updated lists produced in 2008, 2010 and 2011.

According to the latest issue of the Index, for 2011 Norway scored a total of 9.80 on a scale from zero to ten, keeping its position from 2010, when it replaced Sweden as the highest ranked country in the index. North Korea scored the lowest with 1.08, remaining at the bottom in 167th place, the same as in 2010. The Democracy Index for 2011 highlights the impact of the Arab Spring and the greater effects it might have, as well as the impact of the global financial crisis in 2008–09 on politics throughout most of Europe. The Democracy Index score was lower in 2011 than in 2010 in 48 countries out of the 167 that are covered. It was higher in 41 ranked countries, and it stayed the same in 78.
