   How do you calculate cohort life expectancy?

   • And similarly, cohort life expectancy figures can be obtained from 'cohort life tables' (i.e. life tables that rely on age-specific mortality rates observed from tracking and forecasting the death and survival of a group of people as they become older).

   What is a cohort life table?

   • The cohort life table is based on age-specific probabilities of death, which are calculated using observed deaths (mortality) data from the cohort. A cohort life table uses a combination of observed mortality rates for the cohort for past years and projections about mortality rates for the cohort for future years.

   When using cohort life expectancy & projected period life expectancies?

   • When using cohort life expectancy and projected period life expectancy, users should be aware that any calculation will include assumed future changes in mortality and that these become less reliable the further into the future from the projection's base year. 3. Interpreting the probability of dying (qₓ)

   How do you calculate period life expectancy?

   • Period life expectancy figures can be obtained from 'period life tables' (i.e. life tables that rely on age-specific mortality rates observed from deaths among individuals of different age groups at a fixed point in time).

   How is life expectancy calculated in a period E X table?

   • Finding life expectancy figures works the same in a period e x table as it does in a cohort e x table, but the resulting life expectancies will be different as they are calculated using different age-specific mortality data. In both the period and cohort tables for males and females, "year" corresponds to the year of interest.

    For heterogeneity, one approach is to use a multistate life table, which allows the period life table to be adjusted to account for probable transitions in health status. 6 This can more accurately reflect the real experience of the diseased subpopulations over the life course.
