|Note: Life expectancy is a hypothetical calculation of the average age at death for a cohort of persons subject to the age-specific mortality rates observed over a given time period.
Life Table Values are:
nqx = The proportion of persons in the cohort alive at the beginning of an age interval (x) who will die before reaching the end of that age interval (x+n).
lx = The number of persons living at the beginning of an age interval (x) out of an original cohort of 100,000.
ndx = The number of persons who would die during an age interval (x to x+n) out of an original cohort of 100,000.
nLx = The number of person-years that would be lived within an indicated age interval (x to x+n) out of an original cohort of 100,000 alive for all or part of the interval.
Tx = The number of person-years that would be lived after the beginning of an age interval (x) by an original cohort of 100,000 until all are assumed to have died.
ex = The average remaining lifetime (in years) for an individual person who survives to the beginning of an indicated age interval (x).
