Unit: percent of children under age 5
Source: World Health Organization (Global Health Observatory) [WHO.CHILD_UNDERWEIGHT]
Measurement definition and metadata source
Publisher measure: Underweight prevalence among children under 5 years of age (% weight-for-age <-2 SD), survey-based estimates
Weight-for-age below -2 SD, WHO country-level survey estimates, both sexes, no additional disaggregation; retain survey comments. Reference years are irregular survey labels; fieldwork windows were not supplied by the retained projection. Matching year labels do not prove matching collection periods.
Publisher metadata, retrieved . That is when the definition was last checked, not when these figures were published.
Measurement basis: survey-based estimate; reference years are irregular.
Reference-period cadence: irregular survey reference years.
Label correction: These are survey-based country estimates for children under five, both sexes. Missing uncertainty intervals remain absent. Correction record.
These are source-reported readings. A “<” sign means strictly below the stated number. Upper bounds remain visible in tables and downloads; point charts and statistics omit them. A common year can include a reported upper bound.

Same-year comparison · 2021
Every value is for 2021, the latest year before 2026 in this history range with a figure for every selected country, so the values compare directly. Figures for past years can still be revised.
| Country | Value | Year |
|---|---|---|
| Nigeria | 25.5% | 2021 |
Displayed values are rounded. Downloads retain stored numerical precision and identify missing readings.
The year is the one the source reports. Check the source definition and notes for what is measured; the date the data was retrieved is not the date the source published it.
One row per country, indicator and year, with raw values, source links and reuse notices. Thresholds have an empty numeric value and separate number/operator fields; value_kind distinguishes upper bounds from absent readings.
