How this list is built

Every row is a published population observation, ranked highest first. The values were observed in 2022. A place appears only when it publishes this exact metric, so an absent place means missing data rather than a low value. Only published cities with at least 20,000 residents and city-level observations qualify.

  • Compare the displayed value, unit, source date and geographic grain together.
  • A city label does not change a regional observation into a city measurement.
