Overview
Tonga's gini index stood at 27.1 in 2021, a decline of +6.4 from 2015. Tonga ranked 7th globally.
Tonga’s Gini index fell from an all‑time peak of 37.70 in 2000 to a trough of 27.10 in 2021, positioning the kingdom at rank 7 globally for income equality in the most recent World Bank data. This 10.60‑point decline over two decades reflects a steady reduction in relative income dispersion, contrasting with the modestly higher inequality recorded in many high‑income peers such as Belgium (26.60) and Finland (27.70). The downward trajectory, observed across only four years of coverage, suggests that policy measures aimed at expanding social protection and improving access to basic services have been effective in narrowing the gap between the richest and poorest households. Continued emphasis on inclusive growth, particularly through investments in education and health, will be crucial to sustain the current trend and prevent any reversal of the gains achieved since the early 2000s.
