Life expectancy is one of the most commonly used measures of overall health of a population. It is expressed as either the number of years a newborn baby is expected to live, or the expected years of life remaining for a person at a given age, and is estimated from the death rates in a population. Examining causes, patterns and trends in death can also help explain differences and changes in the health of a population, contribute to the evaluation of health strategies and interventions, and guide planning and policy-making.
