The "Failed States Index" debuted in 2005 with a limited assessment of approximately 75 countries; this was expanded to 146 countries in 2006, and then to 177 countries the following year. South Sudan was added to the assessment in 2011. In 2014, The Fund for Peace announced that the ranking would be renamed ""Fragile" States Index", claiming that the controversial term 'failed' had "[become] a distraction away from the point of the Index, which is to encourage discussions that support an increase in human security and improved livelihoods."
