NOTES: The definition of agglomerations varies significantly from city to city, hence the difficulty of compiling an accurate, comparative list of the world's most populous urban areas. 1. Includes metropolitan areas and surrounding urban agglomerations. Agglomerations include a central city and bordering urban areas. Some agglomerations have more than one central city (e.g., Tokyo includes Yokohama and Kawasaki).
