The age structures and marital status differences of married and not married male suicide rates: 12 developed countries.

Male suicide rates, circa 1960, specific to age and marital status for 12 developed countries show married men with lower suicide rates than not married men. This results in differences in the age structures of married and not married suicide rates. We test three explanations of lower married than not married suicide rates: 1) Gibbs and Martin's (1964) marital status integration hypothesis; 2) marital status differences in norms regarding the acceptability of suicide; and 3) Durkheim's societal integration theory. All three explanations are supported by multivariate regressions. The strongest support is for societal integration. The models explain over 80% of the variance in both married and not married male age-specific suicide rates. These regression equations generate predicted suicide rates and these predicted rates are then used to see if they account for the observed age structures of married and not married men. They do in 19 of 24 tests.
