ABSTRACT

Objective: Suicide is one of the major social issues in Japan. According to a report of the National Policy Agency, there were approximately 22000 to 24000 annual suicides between 1994 and 1997 and there have been over 30000 annual suicides in Japan since 1998. For these reasons, we think it is important to discuss the economic factor related to suicides in recent years. 

Method: In this study, we examined suicide rates and the average disposable income per household in Japan in the last 15 years (i.e. 1994–2008) and discuss the statistical analysis of the average disposable income per household and the associated suicide rates.

Results and Discussion: During the research period, annual suicide rates per 100000 population in Japan, ranged from 16.9 to 25.5 among the total population, from 23.1 to 38.0 among men, and from 10.9 to 14.7 among women. The annual average disposable income per household (ten thousand yen) ranged from 424.0 to 549.9. The average disposable income per household was related to the suicide rate among the total population and among men. The average disposable income per household was not related to the suicide rate among women. 

Conclusion: We believe that this discussion will be useful in developing specific suicide preventive measures.
