As of the past century, the analysis and the graphical representation of inequality play a very important role in economics. In the literature, several curves have been proposed and developed to simplify the description of inequality. The aim of this paper is a review and a comparison of the most known inequality curves, evaluating the features of each, with a particular focus on interpretation.

Key words: Bonferroni Curve, Inequality Index, Income Distribution, Lorenz Curve, Zenga Inequality Curve.

Desde el siglo pasado el análisis y representación gráfica de la desigualdad juega un papel importante en la economía. En la literatura varias curvas han sido propuestas y desarrolladas para simplificar la descripción de la desigualdad. El objetivo de este artículo es revisar y comparar las curvas de la desigualdad más conocidas evaluando sus características y enfocándose en su interpretación.

Palabras clave: curva de Bonferroni, curva de Lorenz, curva de Zenga, distribución del ingreso, índice de desigualdad.
