Yesterday, the Institute for Economics and Peace released their annual Global Peace Index (GPI), ranking 158 nations based on their levels of peacefulness.

The good news is that, for the first time since 2009 the world has improved its levels of peacefulness and it's nice that Sub-Saharan Africa is no longer the least peaceful region.

There was bad news for the USA, which ranks way down the list at 88 (below places like Greece, Serbia and Cuba), and for Syria, who saw the biggest fall, dropping more than 30 spots.

NOTE: The rankings and GPI scores were calculated using 23 qualitative and quantitative indicators. To achieve a low score (and thus a lower ranking), the index looked for low levels of internal conflict, cohesive integrated populations, efficient and accountable governments, high levels of regional integration, high enrollment and attendance in primary and secondary schools, low levels of corruption, freedom of the press, and respect for human rights.
