9.7%2023
Publisher note: Viet Nam National Nutrition Surveillance Network, 2023
Unit: percent of children under age 5. 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.
Measurement basis: survey-based estimate; reference years are irregular.
Reference-period cadence: irregular survey reference years.
Displayed values are rounded, with extra precision when needed to keep a positive estimate positive. Downloads retain the full numeric estimate and the publisher's original display text separately.
A “<” sign means strictly below the stated number. Numeric readings and uncertainty endpoints keep their own comparison signs. A number without a sign does not establish certainty or an observed outcome.

History and uncertainty
Charts plot numeric readings. Reported upper bounds create gaps; their values, uncertainty endpoints and source notes remain available in the table and downloads.
