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.

Interpreting this indicator
Life expectancy at birth summarises mortality rates in a particular period. It is not the average age of people who died that year or a guaranteed lifespan for babies born then. A projection describes a modelled future mortality pattern.
