The paper proposes a new measure of the extent to which differences in population health status between the regions of a country are systematically related to regional prosperity. The headcount index of income-related health stratification has a straightforward interpretation as the population-weighted mean difference in the probabilities that the healthier of any two randomly chosen individuals will be from the richer rather than the poorer region from which they are drawn. Moreover, it is well-defined even if only ordinal health data are available, being directly applicable to polytomous categorical variables without the need for either dichotomisation or cardinalisation. The new index is used to examine the evolution of income-related health differences between the regions of Great Britain over the period from 1991 to 2008.
本文提出了一种新的衡量方法，用以评估一个国家各地区之间人口健康状况差异与地区繁荣之间的系统关联程度。与收入相关的健康分层的人口比例指数有一个直观的解释，即任意两个随机选择的个体中，较健康的个体来自较富裕而非较贫穷地区的概率的人口加权平均差异。此外，即使只有序数健康数据可用，它也有明确的定义，可直接应用于多分类变量，无需进行二分法或定量化。新指数用于考察1991年至2008年期间英国各地区与收入相关的健康差异的演变。
