A growth incidence curve presents the growth in income of each percentile over a given period. The shape of the curve indicates the nature of pro-poor growth: a downward-sloping curve indicates that the poor benefit disproportionally more from growth, which is therefore pro-poor, while an upward curve indicates that the better-off do. As Gini coefficients merely quantify the rise or fall in inequality using a scalar measure, they thus tell the policy maker much less than a growth incidence curve about which part of the income distribution changed and affected inequality.
