From Foreign Policy and The Fund for Peace, a failed states index.
“How many states are at serious risk of state failure? The World Bank has identified about 30 ‘low-income countries under stress,’ whereas Britain’s Department for International Development has named 46 ‘fragile’ states of concern. A report commissioned by the CIA has put the number of failing states at about 20.
To present a more precise picture of the scope and implications of the problem, the Fund for Peace, an independent research organization, and FOREIGN POLICY have conducted a global ranking of weak and failing states. Using 12 social, economic, political, and military indicators, we ranked 60 states in order of their vulnerability to violent internal conflict. . . . The resulting index provides a profile of the new world disorder of the 21st century and demonstrates that the problem of weak and failing states is far more serious than generally thought. About 2 billion people live in insecure states, with varying degrees of vulnerability to widespread civil conflict.”
