Life expectancy is an estimate of the average length of time that a person can expect to live, assuming that the current mortality rates for each age group will remain constant for the lifetime of that person. However, mortality rates can be expected to change during a person's lifetime.
Life expectancy estimates are derived from life tables. Life tables may be complete - based on a single year of age and including deaths at all ages, or abridged - based on aggregated age bands. Complete life tables tend to be used for national populations and abridged tables for sub-populations. The abridged life tables have been used to derive all estimates for Victoria.
How life expectancy is calculated in Victoria
Life expectancy has been calculated for the state of Victoria, metropolitan and rural local government areas (LGAs), Department of Health & Human Services regions, and primary care partnership (PCP) areas.
In 2007, these areas were aggregated into five strata on the basis of the 2006 Socio-Economic Indexes for Areas, using Australian Bureau of Statistic (ABS) population estimates and registered deaths.
Estimates of life expectancy for LGAs within Victoria were also calculated from five years (2003–2007) of aggregated mortality and population data from the ABS.
Maps, charts and tables showing details of life expectancies at birth, at 60 and 65 years of age, and across the state of Victoria, are available for download.
