Cohort Life Expectancy

Cohort life expectancy differs from period life expectancy because period life expectancy describes mortality conditions in a single year rather than a cohort's actual mortality history. Cohort life expectancy follows real birth cohorts through their mortality exposure across the life course. The study estimated cohort life expectancy at birth for US birth cohorts born between 1941 and 2000 across states, Washington DC, regions, and the national population. Cohort estimates are useful for examining how environmental, policy, medical, and behavioural exposures vary across time and place.
