Samoa: GNI, PPP (constant 2021 international $)

Key figures

What the numbers say

In 2025, Samoa's GNI, PPP (constant 2021 international $) rose 7.1% on 2024 (from 1.75 billion to 1.88 billion).

Across the 15 yearly changes before that (2010 to 2024), the average change was +3.5% and a typical year strayed about 7.1% from that (the standard deviation). This year's change was 0.5 standard deviations above that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 17.6% in 2023 and the biggest yearly fall was 8.7% in 2021. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2016 to 2025 the straight-line trend is upward, about 46.07 million a year. A straight line explains 59% of the movement over 10 observed years.

What this measures

This indicator provides values for gross national income (GNI) expressed in constant international dollars, converted by purchasing power parities (PPPs). PPPs account for the different price levels across countries and thus PPP-based comparisons of economic output are more appropriate for comparing the output of economies and the average material well-being of their inhabitants than exchange-rate based comparisons. Gross national income is the total income earned by all residents within an economic territory during an accounting period. It is equal to gross domestic product plus earned income receivable from abroad minus earned income payable abroad. This indicator is expressed in constant prices, meaning the series has been adjusted to account for price changes over time. The reference year for this adjustment is 2021. The PPP conversion factor is a currency conversion factor and a spatial price deflator. PPPs convert different currencies to a common currency and, in the process of conversion, equalize their purchasing power by eliminating the differences in price levels between countries, thereby allowing volume or output comparisons of GDP and its expenditure components.

Regional and income-group figures are computed by the World Bank as a gap-filled total.
