How many megacities are predicted by 2020?

By 2020, it was predicted that there would be around 33 megacities globally, which are defined as urban areas with populations exceeding 10 million people. This trend reflects rapid urbanization and population growth in various regions, particularly in developing countries. Cities like Tokyo, Delhi, and Shanghai were among the largest at that time. However, the actual number of megacities may vary due to demographic changes and urban development trends.
