By Urooj Arif & Fiza Rafique — Updated on May 17, 2024
A megacity is a large metropolitan area with a population exceeding 10 million, while a conurbation is an extended urban area formed by the merging of multiple towns or cities, without a specific population threshold.

Key Differences
A megacity is defined by its vast population, typically exceeding 10 million inhabitants, making it a significant hub of economic, cultural, and political activity. A conurbation, on the other hand, refers to an extensive urban area created by the merging of several towns or cities, forming a continuous metropolitan region.
Megacities often emerge due to rapid urbanization and economic opportunities, attracting large populations. They face challenges like congestion, pollution, and providing adequate public services. Conurbations, however, typically develop over time as nearby cities grow and eventually merge, leading to complex urban planning needs and coordination among multiple municipalities.
While both megacities and conurbations signify significant urban development, megacities are primarily defined by population size, whereas conurbations are defined by the geographical merging of urban areas.

A megacity is a very large city, typically with a population of more than 10 million people. Precise definitions vary: the United Nations Department of Economic and Social Affairs in its 2018 "World Urbanization Prospects" report counted urban agglomerations having over 10 million inhabitants.
Conurbation
A conurbation is a region comprising a number of metropolises, cities, large towns, and other urban areas that, through population growth and physical expansion, have merged to form one continuous urban or industrially developed area. In most cases, a conurbation is a polycentric urbanised area, in which transportation has developed to link areas to create a single urban labour market or travel to work area.Patrick Geddes coined the term in his book Cities In Evolution (1915).
