- Mortality
- Highest death rates: Less developed countries, especially sub-Saharan African Countries (Niger, Zambia etc.)
- Infant mortality
- Prime Indicator of socioeconomic development. Most sensitive of age-specific rates.
- Sierra Leone: 163 per 1000 live births.
- Finland: 3 per 1000 live births.
- Falling globally but high variations. Areas with high infant mortality rates have high mortality rates overall.
- Medical Infrastructure
- High levels of medical infrastructure = low mortality.
- Lack of prenatal and postnatal care, a shortage of medical facilities and trained professionals, and ignorance of the need for professional care are major contributors of mortality.
- Economic Development
- Life expectancy is higher in countries with higher levels of economic development.
- Poverty, poor nutrition, a lack of clean water and sanitation increase mortality rates.
- Causes of death in more developed countries: heart disease, strokes, cancer, transport-related accidents, international wars.
- Causes of death in less developed countries: Influenza, pneumonia, TB, malaria, civil wars, natural disasters, AIDS.
- AIDS
- Having major effect on mortality in sub-Saharan Africa.
- 20% of total population affected in Swaziland, Botswana, Zimbabwe.
- Over 40 million worldwide living with HIV/AIDS. (25 million in sub-Saharan Africa)
- Having major effect on mortality in sub-Saharan Africa.
