只要人口中某个亚群体的贫困程度有所下降，而该群体之外的贫困程度保持不变，那么总的贫困程度就应该下降，这似乎是可取的。然而，近年来提出的许多贫困指数都违反了这一简单而有吸引力的性质，我们称之为"亚组一致性"。本文刻画了子群一致性贫困指数类的特征，并确定了与此属性相关的特殊性。版权所有1991年由计量经济学会。
It seems desirable that the overall level of poverty should fall whenever poverty decreases within some subgroup of the population and is unchanged outside that group. Yet this simple and attractive property, which we call "subgroup consistency," is violated by many of the poverty indices suggested in recent years. This paper characterizes the class of subgroup consistent poverty indices, and identifies the special features associated with this property. Copyright 1991 by The Econometric Society.
