Urban area = contiguous built-up land and the people living in it in 2025, drawn the same way for every city regardless of administrative boundaries. Source: GHSL Urban Centre Database R2024A, European Commission, Joint Research Centre (CC BY 4.0); some names adjusted to the city names people use, and country attribution follows the dataset.
Official city limits are drawn differently in every country: some take in farmland and mountains, others stop at the historic core. Ranking cities by those limits mostly ranks boundary decisions. These lists use the built-up area instead, so a city's figure includes its suburbs wherever they are continuous with it, and nothing beyond.
