Not only are they falling behind, but the gap with other developing countries is widening since the 1970s. In 2006, per capita GDP grew only at 2% in fragile states, whereas it reached 6% in other low-income countries. Projections (for example, World Bank, 2008) that fragile states will constitute an even larger share of low-income countries in the future given that many better performing low-income countries graduate to middle-income status. This is a major challenge for development efforts and it has been argued by the Overseas Development Institute that fragile states require fundamentally different approaches from the development models exercised in more resilient countries, because of the different context of risk.
