What the numbers say
In 2024, Tonga's gross savings (% of GNI) rose 0.33 percentage points on 2023 (from 16.67% to 17%).
Across the 30 yearly changes before that (1987 to 2023), the average change was −0.38 percentage points and a typical year strayed about 6.26 percentage points from that (the standard deviation). This year's change was 0.1 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 21.09 percentage points in 1982 and the biggest yearly fall was 16.61 percentage points in 1991. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.
From 2015 to 2024 there is no clear straight-line trend: a straight line explains 25% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.

What this measures
Savings is an amount that represents the part of disposable income (adjusted for the change in pension entitlements) that is not spent on final consumption. Gross savings are calculated as gross national income less total consumption, plus net transfers. This indicator is expressed as a percentage of Gross National Income (GNI) which 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.
Regional and income-group figures are computed by the World Bank as a weighted average.
