Source: UN DESA, World Urbanization Prospects 2025 (cities by the Degree of Urbanisation) · 2025 data. City edges follow the UN’s density rule, so some metros (Hong Kong shows its largest UN city, Tamar; Mumbai excludes satellite towns) are smaller than their usual borders. 2025 values are UN estimates.
Measured, never opinion · every number traceable · nobody can buy a rank.
