Because of that statisticians commonly track members of a particular cohort and predict the average age-at-death for them using a combination of observed mortality rates for past years and projections about mortality rates for future years. The chart here plots the survival curves for individuals in England and Wales from 1851 up to 2011. Because of this, period life expectancy figures are usually different to cohort life expectancy figures. Not, however, that ageing was any easier then than it is now.

Smaller breeds of horses tend to live longer than larger ones. The average person can expect to live a longer life than in the past, irrespective of what age they are.

Since, as far as common knowledge is concerned, there is no one alive that is older than 2021 years old, that would indicate, conclusively, that the mortality rate before the common era waswell100%. Given that life expectancy at birth is highly sensitive to the rate of death in the first few years of life, it is common to report life expectancy figures at different ages, both under the period and cohort approaches.
