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 (+0.58% per year). This anchor is a modelling convention, not an observed population date. Tiles, ranks and comparisons use the recorded base figure 4,150,917, 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.

Why the larger number is not automatically the better answer
The bundled GeoNames settlement record shows 5,638,830; the UN urban-centre estimate is 4,150,917 for 2025. The UN figure is smaller here. “Urban area” therefore must not be described as automatically larger than every administrative record.
Differences in boundaries, source vintages and source definitions can all matter. GeoNames does not supply a population reference date for this local record, so the gap cannot be attributed to recent growth or population loss.
Use a consistent definition for Sydney's comparisons, and do not add suburb values to the parent population: they are not additional people. Read the boundary explanation.
