Name Life expectancy at birth
Definition Describes number of years person can expect to live (at time of birth), if they continued to experience mortality conditions prevailing at the time. Reported separately by sex
Calculation/Formula Calculated from life tables
Unit of Measure Years
Limitations Should be measured over 3 -5 year aggregate periods with 95% confidence intervals to minimise instability due to the small number of events. Where insufficient data exists in routine collections, LE0 is often calculated using models that estimate adult mortality from infant or under 5 mortality that may overestimate LE in the Pacific. Indicator should be reported separately for Males and Females as causes of death (and therefore mortality patterns) often differ markedly by sex.
Purpose/Rationale One of two key mortality indicators providing important description of health status of countries / communities. Countries (populations) with overall high levels of social and economic development usually experience higher e(0) values, than countries with low levels.
