Population data and source
Uses the US Census Bureau Population Clock top ten, retrieved 12 September 2026. These are projections, not live population counts. Different official datasets can give different rankings.
The main source page dates its projections to 1 July 2026. Its embedded top-ten table still displays a 2025 heading, so this quiz identifies the retrieved snapshot explicitly.
