The document summarizes the key findings of the 2008 Legatum Prosperity Index, which takes a holistic view of national prosperity by assessing factors that drive both economic competitiveness and quality of life. The Index ranks over 100 countries based on 22 indicators and 44 sub-indicators related to conditions that foster long-term prosperity. For poorer countries, the most important drivers of competitiveness center around government effectiveness, education, investment, business costs, innovation, and reliance on exports/aid. For richer nations, competitiveness depends more on investment, education, entrepreneurship, and commercializing innovation. Additionally, life satisfaction in wealthy countries relates more to sustained income, health, social support, and individual freedoms.
