Life expectancy at birth is the average number of years a person might expect to live if the conditions at the time of birth continued throughout his/her lifetime. These estimates are calculated by the ABS using life tables which are statistical models generated using age-specific death rates. The life tables used to calculate the data for this indicator are current, or period life tables based on death rates for a short period of time during which mortality has remained much the same. Mortality rates used in the Australian and state and territory life tables are based on death registrations and estimated resident population for the period 2008-2010. The life tables do not take into account future assumed improvements in mortality.
