Portugal is in third place in the ranking of the most peaceful countries in the world. 

Iceland remains the most peaceful country in the world, a position it has held since 2008, the Institute for Economics and Peace said in a statement. It is joined at the top of the index by New Zealand, Austria, Portugal, and Denmark. Bhutan has recorded the largest improvement of any country in the top 20, rising 43 places in the last 12 years, it added.

The Global Peace Index gauges ongoing domestic and international conflict, safety and security in society, and the degree of militarisation in 163 countries and territories by taking into account 23 indicators.

The results this year show that the average level of global peacefulness improved very slightly in the 2019 GPI. This is the first time the index has improved in five years. The average country score improved by 0.09 per cent, with 86 countries improving, and 76 recording deteriorations. The 2019 GPI reveals a world in which the conflicts and crises that emerged in the past decade have begun to abate, but new tensions within and between nations have emerged.
