List of metropolitan areas by population

This page lists the 100 largest metropolitan areas of the world by population. This is a controversial issue rather difficult to quantify, as unlike national subdivisions, there are no defined borders. These figures include suburban areas immediately surrounding a major city and sometimes multiple major cities which may be close enough together to function essentially as one area (e.g. Washington, D.C.-Baltimore).
