VietnamChild Underweight, Under 5 (survey, %)
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 · 2023
Every value is for 2023, 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 |
|---|---|---|
| Vietnam | 9.7% | 2023 |
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.

Each comparison sign applies to its own reading or uncertainty endpoint. Values retain source precision. “Not reported” identifies an absent reading or uncertainty endpoint in this source capture.

Key indicators · latest available
Each country’s most recent figure, so the year can differ between countries and indicators. For a like-for-like comparison of one indicator in a single year, use the same-year comparison above. Figures marked “IMF projection” are forecasts that the IMF revises at each release.
One row per country, indicator and year, with raw values, source links and reuse notices. Empty values mean missing data.
Sources: IMF World Economic Outlook and World Bank. The year under each value is the year it describes. IMF figures for 2026 and later are projections, revised at each release; figures for earlier years can still be estimates. Read the methodology.
