United States Peace Index 2011
Source: Institute for Economics & Peace
The United States Peace Index (USPI) is the first in a series of national peace indices that will build on the work of the Institute for Economics and Peace (IEP) in measuring and understanding the fabric of peace. The Institute produces the Global Peace Index which is the first ever study to methodically rank the nations of the world by their peacefulness and to identify potential drivers of peace. The GPI has become a valued resource and is used by academics, think tanks and governments around the world.
