Annual population growth rate SP.POP.GROW
American Samoa's population growth was -2.03% in 2025, ranked 210th globally. This represents a 26.9% decrease from 2024. Data from World Bank, covering 1961–2025.
Overview
American Samoa's population growth stood at -2.03% in 2025, a decline of +0.43pp from 2024. Based on recent trends, this figure is projected to reach -2.03% by 2025. American Samoa ranked 210th globally.
American Samoa’s population growth has shifted from a modest increase of 2.61 % in 1961 to a sustained decline, reaching –2.03 % in 2025, the lowest figure among 210 economies and the all‑time trough after 65 years of observation. The peak expansion of 3.87 % occurred in 1982, after which the territory entered a gradual deceleration that accelerated in the 2000s, reflecting out‑migration and low fertility. By 2025 the negative rate surpasses that of Tuvalu (–1.79 %) and approaches the decline recorded in the Northern Mariana Islands (–2.34 %), positioning American Samoa among the few jurisdictions with shrinking populations. The reversal from growth to contraction mirrors broader Pacific island trends where limited economic opportunities and climate vulnerability drive demographic outflows. If policies that enhance local employment, improve health services, and address climate‑related displacement are implemented, the downward trajectory could be moderated, potentially stabilising the population in the coming decade.
