We compare distributions of body mass index (BMI) categories among genders in France, the United States, and the United Kingdom on the basis of efficiency and inequality considerations. The new normative criteria that we propose are well suited to the ordinal nature of this variable. Our empirical results, which are supported by robust statistical inference, are twofold. First, BMI categories for the two genders are better distributed in France than in the UK, and in the UK than in the US. Second, BMI categories happen to be more equally distributed among men than among women in all three countries.

男性的体重分布是否比女性更好？针对法国、英国和美国的稳健规范分析*

我们基于效率和不平等的考虑比较了法国、美国和英国的体重指数 (BMI) 类别在性别之间的分布。我们提出的新规范标准非常适合这个变量的序数性质。我们的实证结果得到了稳健的统计推断的支持，是双重的。首先，两种性别的 BMI 类别在法国的分布好于英国，英国的分布好于美国。其次，在这三个国家，BMI 类别在男性中的分布恰好比在女性中更均匀。
