Life table analyses originated as a form of survival analysis in which survival times are grouped into intervals. Hazard or incidence rates are calculated for each interval. Intervals might be constructed by age, calendar time, duration of exposure, or level of exposure (for example, ppm). Rates for the cohort under observation might then be compared with external rates for some large (typically unexposed) population to obtain an estimate of the relative survival of the cohort compared with the external population.
