  • 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)
