Cumulative number of person-years lived by persons age 65 and older, for a cohort of 100,000 persons
Age- and sex-specific mortality rates corresponding to the reference period are applied to a hypothetical cohort, typically of 100,000.
Starting at age 65, the probability of dying at each age or age interval is applied to the number of people surviving to that age or to the beginning of the age interval, respectively.
Rates used by Statistics Canada to calculate life expectancy are calculated with data that excludes the following:
1. Births to mothers who are not residents of Canada
2. Births to mothers who are residents of Canada whose province or territory of residence was unknown
3. Deaths of non-residents of Canada
4. Deaths of residents of Canada whose province or territory of residence was unknown
5. Deaths for which age or sex of the decedent was unknown
