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 2007–2009.
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. Apart from mortality rates themselves (qx), all other functions of the life table are derived from qx. The life tables presented in this publication contain four columns of interrelated information. These functions are:
qx—the proportion of persons dying between exact age x and exact age x+1. It is the mortality rate, from which other functions of the life table are derived;
Lx—the number of person years lived within the age interval x to x+1; and
ex—life expectancy at exact age x.
These documents will be presented in a new window.
