List of country subdivisions by population
This article contains lists of the most populous administrative country subdivisions in the world. Excluded are regions defined for convenience that do not have their own single government: e.g. Calabarzon, East China, Kantō region and Northeastern United States.
List of first-level administrative subdivisions by population
The following is a ranked list of the 62 first-level administrative subdivisions worldwide with populations that are, as of the latest government data (including projections), over 20 million, along with a country of comparable population size, the country that the subdivision belongs to, the date the population statistic is taken from, its capital, its area, population density, and its largest metro area. The latest data issued by the country's government is used, and those subdivisions which are the largest in their respective countries are shown in bold. Countries which have a high proportion of their population enumerated in the largest subdivision include the United Kingdom (80.3% in England) and Pakistan (53.7% in Punjab). England appears on this list but does not have a single government because it is a constituent country.

List of second-level administrative subdivisions by population
Second-level divisions are those subdivisions that are under the first level of administration (states, provinces, etc...) and they go by many names, such as counties, districts, divisions, and regions, but these names vary by country. The list below displays every single second-level subnational division in the world with a population over 10 million, as well as what they are called (a district, county, region?), area, density, the country and first-level subdivision they belong to, the date the population figure dates from, and a country of comparable population size. Only districts and divisions that have a unified administration or government of any kind are listed, so for example, non-governmental statistical regions, such as Media Markets or Combined Statistical Areas in the U.S. are excluded, but Indian Divisions, as they involve some form of administration (mostly concerning revenue), are included.
