There are twenty-three indicators that make up the Global Peace Index. Countries are scored on these indicators on a range from 1-5 where a country is considered most peaceful.
The Global Peace Index is a project of the Institute of Economics and Peace in the US. It represents a ground-breaking milestone in the study of peace.
This is the first time an Index has been created to rank nations of the world by their peacefulness and identifies some of the drivers of peace.
