Explanation

Development is more than growth – includes improved living standards, reduced poverty, better health and education, and expanded opportunities. Measured by: GDP per capita, Human Development Index (HDI), poverty rates.

Development indicators: life expectancy, literacy rates, access to clean water, infant mortality, school enrollment. Nigeria ranks low on HDI despite relatively high GDP due to inequality and poor social services.

Barriers: corruption, poor infrastructure, low human capital, debt burden, unfavorable trade terms, brain drain. Strategies: investment in education and health, infrastructure, good governance, diversification away from oil.
