Bulgaria · Neonatal Mortality, 0–27 Days (WHO)
2.62024
Unit: per 1,000 live births. Publisher measure: Neonatal mortality rate (per 1000 live births).
Neonatal mortality during the first 28 completed days of life (age 0–27 days), 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.

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 · 61 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.
