About these numbers
Source: UN DESA, World Urbanization Prospects 2025. Reference: 2025 annual estimate. Live method: exponential projection from modelling anchor 2025-01-01 using UN 2025–2026 annual growth (+2.12% per year). This anchor is a modelling convention, not an observed population date. Tiles, ranks and comparisons use the recorded base figure 458,225, not the ticking estimate. Country/world denominators are World Bank values and can differ in date and method from local/UN values. Ranks cover only records with the same definition label in this database, not all cities in the world.
