MEGACITIZENS.com covers not only qua definition 'Megacities' but the so-called 'Global Cities' as well. Megacitizens live in both, Megacities as well as Global Cities.

A Megacity is a metropolitan area with a minimum population density of 2,000 people per square kilometre, a Megacity is associated with conurbation, overpopulation, and pollution. Although this description sounds very negative, Megacities also represent progress and development. Today there are over 20 Megacities in the world and each of them has over 10 million inhabitants. These urban destinations are usually the centres for business and trading in their respective regions and are important in terms of economic development in the nations they belong to. An example for a Megacity would be Manila (Philippines).

A Global City differs from a Megacity in possibly two points. First, a Global City did not yet (and/ or will not) reach the number of inhabitants to make it a Megacity, which is 10 million. A Global City however does make up for the lack of population with international political, financial, geographical or other importance. While a Megacity does not have to be for example politically of international relevance to be a Megacity, a Global City has to. A Global City is for example Brussels, the home of the institution of the European Union - even though Brussels (Belgium) has only just about half a million inhabitants.
