Communities and Urban Regeneration

Abstract

According to Demographia (2020), there are 35 megacities with a population of more than 10 million people in the world. As 51.4% of the world’s population are living in built-up areas, the number of megacities has increased, alongside the dramatic expansion of urbanization and rapidindustrialization. The growth of cities is also driven by national policies thatfoster megacities, reinforcing their global competitiveness.
