Most of researchers used RMR (Relative Mortality Rate) to study marital status and mortailty trying to reveal the selection and protection effects of marriage on death. This study instead employs life table technique to analyze their effects on life expectancy. Although this study does not intend to differentiate the relative importance between selection and protection effects, through modeling various hypothetical cohort's marital experiences in life course allow us to control a11 other factors than the sole effect of marital status. This study finds that: 1) remaining constantly in married status results in longer life expectancy than the never-married, ever divorced, and widowed for both sexes; 2) remaining constantly in married status grant more steady protection for females than for males; 3) comparing to males’ marital-specific age pattern of life expectancy, it seems that females have more steady gains in life expectancy, which suggests that protection effect of marriage has more intricacy with selection effect among males than females; 4) comparing the change between 1981 and 1991, married females' odds in life expectancy than other marital status decreased. The decrease indicates an increased capability to lead independent life among females.
