Group of 7 countries (G7) Compared by Health > Life expectancy > Life expectancy at birth > Total
DEFINITION:
Life expectancy measures how long on average people would live based on a given set of age-specific death rates. However, the actual age-specific death rates of any particular birth cohort cannot be known in advance. If age-specific death rates are falling (as has been the case over the past decades in OECD countries), actual life spans will be higher than life expectancy calculated with current death rates.
