»City Population« provides a page tabulating all urban agglomerations of the world with at least 1 million inhabitants. To compare the population of cities, which have rather arbitrary boundaries, is not really reasonable.
For definition of terms, please consult the glossary.
This is an international website. Therefore, not the English name of a city is given in the first place, but its native name. English or other names are given in brackets. For names in languages not written by using the Roman alphabet, the locally official transliteration system has been used (if one exists). Diacritical marks are displayed if such information is available.

As explained in the glossary, an agglomeration requires an economically and culturally linked population. Thus, most people from both sides of the border should be able pass it without any obstacles.
