The life tables in this spreadsheet 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 for the Australian and state and territory life tables are based on death registrations and estimated resident population for the period 2010–2012. The life tables do not take into account future assumed improvements in mortality.
A life table may be complete or abridged, depending on the age interval used in the compilation. Life tables in this spreadsheet are complete life tables—they contain data by single years of age. Abridged life tables contain data for five-year age groups. Life tables are presented separately for males and females.
The life table depicts the mortality experience of a hypothetical group of newborn babies throughout their entire lifetime. It is based on the assumption that this group is subject to the age-specific mortality rates of the reference period. Typically, this hypothetical group is 100,000 in size.
To construct a life table, data on population, deaths and births are needed. Mortality rates are smoothed to avoid fluctuations in the data. The mortality rate (qx), is the main function of the life table, all other functions are derived from it. The life tables presented in this publication contain four columns of interrelated information. These functions are:
Life tables for the states and territories are produced on the same principles as the Australian life tables with the exception of the crude m(x) rate. Crude m(x) rates are graduated using the Australian life table through the application of the Lidstone transformation. This overcomes problems associated with excessive noise in the single year of age rates. In addition, some smoothing and suppression of outliers is often required to achieve reasonable mortality curves with satisfactory goodness-of-fit statistics.
State and territory life tables produced by the ABS are available for:
