Life Tables and Age-Specific Mortality
Captions available
The idea
A life table divides a population into age intervals and reports mortality rate and remaining life expectancy for each interval, built from cohort survival data.
In practice
A sheep-population life table shows mortality spiking sharply between two age intervals rather than staying constant.
Where people slip
A life table's mortality rate is age-interval-specific, not one population-wide rate — the same population shows different risk at different ages.
