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.

At the same point in time

Latest comparable common year within this selection: 2026.

United States minus Portugal: 338,640,132 people.

Calculated by World in Stats from the named source values. This comparison includes 2026 projections, not observed outcomes. Differences are not causal effects.

Interpreting this indicator

Use population to compare the scale of countries, not their living standards. Annual population values refer to a reference date; they are not a real-time census. The World Population clock interpolates separate UN projections, so its number can differ from this annual series.

Understand percentages, rates and uncertainty

Data availability varies by country and year. Compare the same definition and time period. Revisions may change historical observations; these values belong to the snapshot retrieved on 13 October 2026.

This feed does not supply uncertainty intervals for these observations. No ranking or causal explanation is inferred.
