The Institute for Economics and Peace unveiled its annual Global Peace Index at a ceremony in London yesterday, indicating that the world had becomes “slightly more peaceful” in the last year. 

Despite this, the Middle East and North Africa region saw an overall decline in peace during the unrest of the Arab Spring over the last year, making it the least peaceful region globally.

Qatar, however, saw no change in its ranking as 12th most peaceful country in the world, leading the Arab World for the fourth year in a row. Qatar also came out ahead of a number of Western democratic countries, including  Sweden (14), Germany (15), Britain (29), and the United States (88). 

Once-ally Syria saw the biggest drop in peace, according to the report, plummeting 30 places to 147th of 158 countries. Somalia rounded out the bottom, while Iceland took the top spot.

Among the criteria judged are the perceived criminality in society, homicide rates, jailed populations, access to weapons, violent demonstrations, and political instability.
