The Big Ten Student Suicide Study was undertaken from 1980-1990 to determine the suicide rates on Big Ten University campuses. The study design attempted to address many of the statistical and epidemiological flaws identified in previous studies of campus student suicides. The 10-year study collected demographic and correlational data on 261 suicides of registered students at 12 midwestern campuses. The largest number of suicides for both males and females were in the 20-24-year-old age group (46%), and amongst graduate students (32%). The overall student suicide rate of 7.5/100,000 is one half of the computed national suicide rate (15.0/100,000) for a matched sample by age, gender, and race. Despite the overall lower suicide rate, the analyses revealed that students 25 and over have a significantly higher risk than younger students. Although women have rates roughly half those of men throughout their undergraduate years, graduate women have rates not significantly different from their male counterparts (graduate women 9.1/100,000 and graduate men 11.6/100,000).
“十大联盟学生自杀研究”于1980年至1990年开展，旨在确定十大联盟大学校园的自杀率。该研究设计试图解决先前校园学生自杀研究中发现的许多统计和流行病学缺陷。这项为期10年的研究收集了中西部12个校区261名注册学生自杀的人口统计学和相关数据。男性和女性自杀人数最多的是20至24岁年龄组（46%），以及研究生（32%）。总体学生自杀率为7.5/10万，是按年龄、性别和种族匹配的样本计算出的全国自杀率（15.0/10万）的一半。尽管总体自杀率较低，但分析显示，25岁及以上的学生比年轻学生面临的风险显著更高。尽管在本科阶段女性的自杀率大致是男性的一半，但研究生阶段女性的自杀率与男性没有显著差异（研究生女性为9.1/10万，研究生男性为11.6/10万）。
