Income share held by lowest 10% SI.DST.FRST.10
Tonga's income share bottom 10% was 4.00% in 2021, ranked 7th globally. This represents a 25.0% increase from 2020. Data from World Bank, covering 2000–2021.
Overview
Tonga's income share bottom 10% stood at 4.00% in 2021, a rise of +0.80pp from 2015. Tonga ranked 7th globally.
Tonga’s share of total national income accruing to the bottom 10 % of the population rose from 2.40 % in 2000 to 4.00 % in 2021, marking the highest level recorded in the series and placing the kingdom seventh globally in the most recent year. The upward movement reflects a modest improvement in the distribution of income to the poorest decile over the 21‑year span, although the absolute share remains well below the median for the region. By comparison, Armenia recorded an identical share of 4.00 % in the same year, while the Czech Republic was slightly lower at 3.90 %, underscoring that Tonga’s progress aligns with the upper end of its peer group. The trend suggests that continued fiscal reforms aimed at expanding social protection and enhancing low‑income productivity could sustain or further raise the bottom‑10 % share, while stagnation in these policies might reverse the gains achieved since the early 2000s.
