An earlier study (Lester, 1984) found that, in the United States, cohorts that had a high suicide rate at one point in their life span had low suicide rates at other points, and vice versa. This result suggested that only a limited number of people in each cohort were suicide-prone. The present paper replicates this result, using Canadian data from 1921 to the present time.
一项早期研究（莱斯特，1984年）发现，在美国，那些在其生命历程中的某个阶段自杀率较高的人群在其他阶段自杀率较低，反之亦然。这一结果表明，每个队列中只有有限数量的人易于自杀。本文使用1921年至今的加拿大数据重复了这一结果。
