The migration of young men from Mexico to the United States generates a deficit of men and a relative abundance of women in many Mexican communities, but the implications of this imbalanced sex ratio for Mexicans’ risks of criminal victimization has received little attention. We merge individual-level data from 19,551 inhabitants of 136 municipalities covered in the 2002 Mexican Family Life Survey with aggregated data from the 2000 Mexico population census to examine the association between the municipality-level percentage of men at ages 15 to 39 and self-reports of recent violent victimization. Multilevel logistic regression modeling reveals a curvilinear relationship between percent male and the likelihood of experiencing a violent victimization, with victimization risks lowest in municipalities characterized by either unusually low or unusually high numbers of men. Respondents residing in municipalities having a more balanced sex composition experience the highest risk of victimization. The risk of experiencing a violent victimization also varies sharply by age, gender, socioeconomic status, and community characteristics.

在许多墨西哥社区，年轻男性从墨西哥移民到美国造成男性短缺和女性相对丰富，但这种性别比例失衡对墨西哥人犯罪受害风险的影响很少受到关注。我们将 2002 年墨西哥家庭生活调查涵盖的 136 个城市的 19,551 名居民的个人数据与 2000 年墨西哥人口普查的汇总数据合并，以检查城市级 15 至 39 岁男性百分比与自我报告之间的关联最近的暴力受害。多级逻辑回归模型揭示了男性百分比与遭受暴力侵害的可能性之间的曲线关系，在男性人数异常少或异常多的城市中，受害风险最低。居住在性别构成较为均衡的城市的受访者受害风险最高。经历暴力受害的风险也因年龄、性别、社会经济地位和社区特征而有很大差异。
