Abstract. Concentration indices are frequently used to measure inequality in one
variable over the distribution of another. Most commonly, they are applied to
the measurement of socioeconomic-related inequality in health. We introduce
the user-written command conindex, which provides point estimates and
standard errors of a range of concentration indices. The command also graphs
concentration curves (and Lorenz curves) and performs statistical inference
for the comparison of inequality between groups. We offer an accessible
introduction to the various concentration indices that have been proposed to
suit different measurement scales and ethical responses to inequality. We also
demonstrate the command's capabilities and syntax by analyzing wealth-related
inequality in health and health care in Cambodia.
