In many instances, individual health statuses are self-reported on several ordinal scales. The ordinal nature of the data creates some challenging problems in the measurement of inequalities of various distributions of health statuses in a population. In this paper, we propose and discuss a class of measures of inequalities of heath status distributions based on such ordinal data. Our measures are easy to compute and have some desirable properties often required for a reasonable measure for health inequality.
Health inequality Self-reported health status Additivity Invariance of parallel shifts Normalization Simple aversion to median-preserving spreads
