Japan · Infant Mortality, Under Age 1 (WHO)

1.82024

Unit: per 1,000 live births. Publisher measure: Infant mortality rate (probability of dying between birth and age 1 per 1000 live births).

Infant mortality probability before the first birthday (age 0–11 months), both sexes, expressed per 1,000 live births under reference-year mortality conditions.

Measurement basis: UN Inter-agency Group for Child Mortality Estimation (UN IGME) modelled or adjusted mortality probabilities/rates, disseminated by WHO.

Reference-period cadence: annual.

Source update cadence: annual. This does not establish a publication date for an individual reading.

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.

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 · 76 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.
