Life expectancy

Life expectancy at age 60

The average number of years that a person of 60 years old could expect to live, if he or she were to pass through life exposed to the sex- and age-specific death rates prevailing at the time of his or her 60 years, for a specific year, in a given country, territory, or geographic area.

Life expectancy at age 60 reflects the overall mortality level of a population over 60 years. It summarizes the mortality pattern that prevails across all age groups above 60 years

Mortality and burden of disease

The lack of complete and reliable mortality data, especially for low income countries and particularly on mortality among adults and the elderly,  necessitates the application of modelling (based on data from other populations) to estimate life expectancy. WHO uses a standard method as explained above to estimate and project life tables for all Member States using comparable data. This may lead to minor differences compared with official life tables prepared by Member States.

Life expectancy at age 60 years is derived from life tables and is based on sex- and age-specific death rates. Procedures used to estimate WHO life tables for Member States vary depending on the data available to assess child and adult mortality. Three basic methods have been used for this revision. In all three cases, UN-IGME estimates of neonatal, infant and under-5 mortality rates were used. WHO has developed a model life table using a modified logit system based on about 1800 life tables from vital registration judged to be of good quality to project life tables and to estimate life table using limited number of parameter as input. 1) When mortality data from civil registration are available, their quality is assessed; they are adjusted for the level of completeness of registration if necessary and they are directly used to construct the life tables. 2) When mortality data from civil registration for the latest year are not available, the life tables are projected from available years. Estimated under-5 mortality rates and adult mortality rates, or from under-5 mortality rates only, using a modified logit model to which a global standard (defined as the average of all the 1800 life tables) is applied. 3) When no useable data from civil registration are available, the latest life table analyses of the UN population Division were used(8).

The numbers of deaths estimated from life table and population by age groups are aggregated by relevant region in order to compute regional life tables.
