Suicide in the State of Maryland, 1970-80

A univariate and multivariate analysis of factors associated with suicide for residents of the State of Maryland was conducted. The investigation was statistically oriented in its approach, examining the relationships of age, race, sex, marital status, and month of death with suicide. Besides the usual death rates, percentages, and age-specific rates, a discriminant analysis was performed to test this approach. Data were obtained on all suicides of Maryland residents, regardless of where the deaths occurred. Univariate analysis showed that the relationships between suicide and age, race, sex, and marital status are consistent with those in the literature. No significant relationship appeared to exist between the month of death and suicide. During multivariate analysis, the discriminant function correctly predicted 80 percent of all the deaths, 74 percent of suicides, and 80 percent of all other causes, in their respective categories.
