About these numbers
Source: GeoNames administrative-unit record. Reference: Population reference date not supplied in local record; GeoNames record modified 2026-04-16 (not the population date). Live method: exponential projection from modelling anchor 2025-07-01 using World Bank national growth (2025); not measured local growth (−0.13% per year). This anchor is a modelling convention, not an observed population date. Tiles, ranks and comparisons use the recorded base figure 1,470,336, 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.
