This study examined the relationship between suicide rates among men since 1975 and rates of unemployment and labour force participation in 20 countries. Previous research has found statistically significant correlations between suicide and unemployment rates over time among young people in a number of countries. This study has extended this research to include different age groups of men. The findings for younger workers largely confirm the findings of previous studies. Among older workers, however, unemployment and suicide rates are largely unrelated, notable exceptions including Japan and the USA. The implications of this finding for policy making towards older workers are discussed.
