Mauritania: Adjusted savings, net national savings (% of GNI)

Key figures

Over five years it is up 10.38 percentage points from 21.04% in 2016. Since 1975 it is up 29.27 percentage points from 2.15% in 1975. The World Bank has no value for 13 of the years in between; the chart leaves those gaps open rather than joining across them.

What the numbers say

In 2021, Mauritania's adjusted savings, net national savings (% of GNI) rose 2.32 percentage points on 2020 (from 29.09% to 31.42%).

Across the 30 yearly changes before that (1977 to 2020), the average change was +0.63 percentage points and a typical year strayed about 10.75 percentage points from that (the standard deviation). This year's change was 0.2 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 37.25 percentage points in 1994 and the biggest yearly fall was 28.55 percentage points in 1995. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2012 to 2021 there is no clear straight-line trend: a straight line explains 9% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.

What this measures

Net national savings are equal to gross national savings less the value of consumption of fixed capital. 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.
