PROJECTION · 2025 / 2026 · dashed lines; diamonds only in 2026. Unclassified source values are not certified observed.How to read this chart
Unclassified means the provider did not supply an explicit observation/estimate flag. It does not mean the value is unreliable. Source or methodology changes can affect trends across editions.
Countries publish data on different schedules. A shorter line or a gap means the source has no value for that country and year. Missing values are not zero. Only separately sourced official estimates or projections may fill gaps; we do not invent intermediate values. Use Table to inspect individual years.
The source-check date tells you when we retrieved the data, not the year it describes. Use the observation year when citing a value.
Compare the same definition and period. Differences are descriptive, not causal. National measurement methods may differ; crude rates are not age-standardised. Missing uncertainty intervals in this feed do not mean an estimate is exact.

Life expectancy at birth
Life expectancy at birth indicates the number of years a newborn infant would live if prevailing patterns of mortality at the time of its birth were to stay the same throughout its life.
deaths per 1,000 live births · 216/217 profiles · latest year by country 2026–2026Infant mortality
Infant mortality rate is the number of infants dying before reaching one year of age, per 1,000 live births in a given year.

Under-five mortality rate is the probability per 1,000 that a newborn baby will die before reaching age five, if subject to age-specific mortality rates of the specified year.
