Publisher note: Yemen Multiple Indicator Cluster Survey 2022-2023, Survey Findings Report. Yemen: Central Statistical Organization and United Nations Children’s Fund.

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.
