Actuarial survival is the estimated survival for a group of people diagnosed with cancer based on cohort data and life tables.

Life tables look at the number of the cohort who are alive and under observation at the beginning of each year, the number dying in each year, the number lost to follow-up each year, the conditional probability of survival for each year, and the cumulative probabilities of survival from the beginning of the observation to the end of each year.

It is most useful when data are only available in grouped categories.
