Tonga · Maternal Deaths (WHO Estimates)
22023
Unit: deaths. Publisher measure: Number of maternal deaths.
Estimated annual number of maternal deaths during pregnancy, childbirth or within 42 days after termination of pregnancy, from causes related to or aggravated by pregnancy or its management; accidental and incidental causes are excluded.
Measurement basis: UN Maternal Mortality Estimation Inter-Agency Group (MMEIG) Bayesian model estimates disseminated by WHO; counts, not maternal mortality ratios.
Reference-period cadence: annual.
Source update cadence: every 3–5 years. This does not establish a publication date for an individual reading.
- Modelled annual number of maternal deaths, not deaths per live births. Pregnancy-related deaths extend through 42 days after termination; accidental and incidental causes are excluded.
- Numeric estimates and both uncertainty endpoints preserve source precision. A rounded publisher display of 0 can represent a positive estimate; it is not converted to zero.
- Reference years are annual, while WHO describes dissemination every 3–5 years. The interval confidence level and official observation publication vintage are not established by this capture.
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.

Download this immutable source capture · Source and coverage corrections
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.
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.
Reported estimates and uncertainty · 39 rows
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.
