Quality of life and human development are measured by more than just Gross Domestic Product (GDP). The Human Development Index (HDI), which is calculated every year by the United Nations, measures long-term well-being and quality of life through factors such as life expectancy, education and income.
Compared to most countries on the continent, African countries with formal diamond mining do well in terms of human development; among the countries covered in the map, South Africa, Botswana and Namibia are all in the top six. However, all of them would be doing even better were it not for the impacts of HIV/AIDS, which is affecting Africans in every country by decreasing quality of life and life expectancy. The revenues generated from diamonds are helping the communities where they are found to fight this disease.
