What the numbers say

  • 양천구, South Korea leads at 24,755 people/km².
  • junggu, South Korea sits at the other end with 12,103 people/km².
  • The middle of this ranking is 16,498 people/km², across 30 places that publish the metric.
  • The spread between first and last is 12,652 people/km².

What this measures

Every row is a published population density observation measured in people/km², ranked highest first. The values were observed in 2024. A place appears only when it publishes this exact metric, so an absent place means missing data rather than a low value.

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