   Period life expectancies are a measure of current mortality risk and are most useful as a tool for comparing two subgroups of a population. . Healthy life expectancies are cal-culated on a period basis and the definition of healthy is generally both self-assessed and subjective. Cohort healthy life expectancies cannot be robustly calculated.

   Two different approaches to calculating life expectancy at birth are compared: period life expectancy (based on death rates in one particular year) and cohort life expectancy (based on average lifespans).

8. People also ask

   What is a period life expectancy?

   • Period life expectancies use mortality rates from a single year (or group of years) and assume that those rates apply throughout the remainder of a person's life. This means that any future changes to mortality rates would not be taken into account. Period life expectancies are a useful measure of mortality rates experienced over a given period.

   How often are life expectancy tables published?

   • Tables are published annually. Period life expectancy by age and sex for England. Each national life table is based on population estimates, births and deaths for a period of three consecutive years. Tables are published annually. Period life expectancy by age and sex for Wales.

   Why are period life expectancies lower than cohort life expectancy?

   • Difference between period and cohort life expectancies Period life expectancies tend to be lower than cohort life expectancies because they do not include any assumptions about future improvements in mortality rates. Figure 1 shows period and cohort life expectancy at birth for males and females from 1841 to 2020 for England and Wales.

   Does period life expectancy match cohort life expectancies?

   • Period life expectancy would match cohort life expectancy only if there were no change in age-specific mortality rates over time. This is an extremely unlikely scenario as, in reality, these change from year to year. 3. Uncertainty in the cohort life expectancy projections

   How do we calculate life expectancy?

   • It is used to assess and set a number of important policies that impact on everyday life, for example, setting the State Pension age and targeting health policy initiatives. To calculate life expectancy, we use a tool called a life table, which shows, for each age, what the probability is that a person will die before his or her next birthday.

   How is cohort life expectancy calculated?

   • For example, cohort life expectancy at age 65 years in 2020 would be worked out using the mortality rate for age 65 years in 2020, for age 66 years in 2021, for age 67 years in 2022, and so on. Importantly, the cohort life table takes into account observed and projected improvements in mortality for the cohort throughout its lifetime.
