CompareFollow the selected indicator from its value to its history.
Displayed reference years run from 2023 to 2025. These are each indicator's published periods, not a single-year country snapshot. A comparison may use an older common period; follow Compare to check it.
The notes below use the currently published values. Years and sources may differ across indicators.
The US population total and growth rate answer different questions: size and change. Their sources and years may differ, so multiplying them does not yield an official change count. Use consecutive periods from the same source to check a count.
