How Tonga's population changed across key years (World Bank estimates).
Overview
Tonga, an upper-middle-income country in the East Asia & Pacific region, has experienced a modest population decline in recent years. The latest 1-year growth rate is -0.40%, while the 10-year average growth rate is -0.23%, indicating a sustained trend of negative population change. This decline is likely driven by factors such as emigration and low fertility rates, common among many Pacific island nations. Despite the shrinking population, Tonga maintains a relatively high income level for the region, which may influence migration patterns and demographic structure. The country's small population size (ranked 193rd globally) means that even minor absolute changes can produce noticeable percentage shifts.
