Sierra Leone: Prevalence of undernourishment (% of population)

Key figures

What the numbers say

In 2024, Sierra Leone's prevalence of undernourishment (% of population) fell 1.1 percentage points on 2023 (from 26.4% to 25.3%).

Across the 22 yearly changes before that (2002 to 2023), the average change was −1.07 percentage points and a typical year strayed about 2.06 percentage points from that (the standard deviation). This year's change was 0.0 standard deviations below 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 1.8 percentage points in 2015 and the biggest yearly fall was 4.4 percentage points in 2005. 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 1% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.

How it compares

In 2024, Sierra Leone had the 14th highest value of the 164 economies reporting that year. Higher is not always better: for some indicators the lowest value is the one to aim for. See the full ranking.

What this measures

Prevalence of undernourishment is the percentage of the population whose habitual food consumption is insufficient to provide the dietary energy levels that are required to maintain a normal active and healthy life. Data showing as 2.5 may signify a prevalence of undernourishment below 2.5%.

Limitations: The prevalence of undernourishment is a model-based estimate, and its reliability depends on the quality of the data used to estimate the model parameters. Measurement errors may affect estimates of dietary energy consumption derived from household surveys and Food Balance Sheets. Because of the probabilistic nature of the estimation and uncertainty associated with the model parameters, the precision of PoU estimates is generally low. National-level PoU point estimates are available only when they exceed 2.5 percent.

Regional and income-group figures are computed by the World Bank as a weighted average.
