The Global Peace Index (GPI) seeks to determine what cultural attributes and institutions are associated with states of peace. It ranks 153 countries by their relative states of peace using 23 indicators.


The most and least peaceful states, 2011
Rank Country Score   Rank Country Score
1   Iceland  1.148     149  North Korea   3.092
2   New Zealand 1.279     150  Afghanistan 3.212
3   Japan 1.287     151  Sudan 3.223
4   Denmark 1.289     152 Iraq 3.296
5   Czech Republic   1.320     153  Somalia 3.379

Iceland regained first place due to restored political stability. Island nations generally fare well, with most in the top half of the GPI, as do small, stable and democratic countries.
