What is Megalopolis?

In today's rapidly urbanizing world, the concept of megalopolis has become increasingly relevant. But what exactly is a megalopolis, and how does it differ from other types of urban areas?

A megalopolis (Greek: μέγας, "great" + πόλις, "city") is a massive metropolitan area that comprises several cities or urban agglomerations that have merged to form a single, enormous conurbation. Megalopolises are characterized by their immense size, population density, and economic influence.

Defining a Megalopolis

The term "megalopolis" was first coined in the 1960s by American urban planner and geographer, Jean Gottman. According to Gottman, a megalopolis is a region that spans at least 100 miles (160 kilometers) along a transportation corridor, such as a highway or a rail line, and has a population of over one million people.

Characteristics of Megalopolises

Megalopolises share several distinct characteristics:

Massive Population: Megalopolises are home to millions of people, often exceeding 10 million residents.
Urban Agglomeration: A megalopolis is formed by the merging of multiple cities or urban areas into a single, cohesive entity.
Economic Hubs: Megalopolises are major economic drivers, with significant industries such as finance, technology, manufacturing, and services.
Transportation Corridor: Megalopolises typically have a dominant transportation artery, like a highway, rail line, or airport, which connects the various urban centers within the region.
