life expectancyAverage lifespan that can be presumed of a person at birth. It depends on nutrition, disease control, environmental contaminants, war, stress, and living standards in general. There is a marked difference between industrialized countries, which generally have an ageing population, and the poorest countries, where life expectancy is much shorter. In Malawi, life expectancy is currently 42; in Nigeria 47; in Ethiopia 49. In Zambia, the AIDS epidemic brought the life expectancy down to a record 33 years, according to government figures released in 2003.
