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
This expresses the probability of dying before age five per 1,000 live births. It includes infant mortality: do not add the two rates together. It is not the percentage of all children who died during one calendar year.
