What difference does the choice of SES make in health inequality measurement?
探讨了在测量健康的社会经济不平等时，选择不同社会经济地位指标（如消费或资产财富指数）的影响，发现对五岁以下儿童营养不良的不平等测量结果影响不大。
This note explores the implications for measuring socioeconomic inequality in health of choosing one measure of SES rather than another. Three points emerge. First, whilst similar rankings in the two the SES measures will result in similar inequalities, this is a sufficient condition not a necessary one. What matters is whether rank differences are correlated with health - if they are not, the measured degree of inequality will be the same. Second, the statistical importance of choosing one SES measure rather than another can be assessed simply by estimating an artificial regression. Third, in the 19 countries examined here, it seems for the most part to make little difference to the measured degree of socioeconomic inequalities in malnutrition among under-five children whether one measures SES by consumption or by an asset-based wealth index.
