How close does the observed distribution of an economic variable approach its optimal distribution? The reply to this question leads immediately to the topic of inequality. Attempts are made to quantify inequality for a variety of purposes, one of the most notable of which has a regulating function over its desirable characteristics for improved market performance. In this context, the traditional metrics of inequality are reviewed and, without underestimating their usefulness, a new metric that distinguishes two dimensions - homogeneity and inclusion - is proposed. Finally, a combination of both dimensions for expressing the level of good in the market is proposed.
