Mortality table that includes data only on people who have recently purchased life insurance. Experience shows that such people have a lower mortality rate in the years immediately following their purchase of insurance than those who have been insured for some time, probably because they have recently passed medical and other tests, and because they are younger. For example, a select mortality table would show the number of deaths per 1000 of individuals age 30 who have been insured for one year. An ULTIMATE MORTALITY TABLE shows the rate of the group, exclusive of the initial period after the purchase of insurance. An aggregate mortality table includes all data.
