When health status is an ordered response variable, Allison and Foster (2004) postulate that a distribution Q ?exhibits more inequality than a distribution P ?if Q ?is obtained from P ?via a sequence of median preserving spreads. This paper introduces a parametric family of inequality indices which are founded on the Allison and Foster ordering.
