Life Table Approaches to Demographic Analysis
Initially, the life table was developed to analyze the mortality process. Currently, its application is not restricted to mortality alone but to all measurable processes involving attrition or accession to aggregate size. The life table approach is being used in fertility, labor force, nuptiality, evaluation of contraceptive effectiveness, breast feeding, and so forth. As a general rule, life tables can be used when durations of exposure are central to whether the events being studied have occurred (Smith, 1980). It is important to remember that life table analysis is particularly useful if the events under study are nonrenewable. For instance, this approach is useful in the study of birth order statistics or parity-specific fertility behavior rather than age-specific fertility rates based on number of children born. Events such as births and marriages are renewable but order-specific births and marriages are not.
