Megacities: New York (Number 11) and Los Angeles (Number 26)
In 1950, there were just two cities in the world—New York and Tokyo—that were considered “megacities,” that is, urban areas with populations of at least 10 million. By 2018, there were thirty-four such cities and the United Nations estimates that by 2035 there will by forty-eight megacities. America has just two megacities, New York-Newark (18.8 million) and Los Angeles-Long Beach-Santa Ana (12.4 million).
Tokyo (37.39 million), Delhi (30.29 million); Shanghai (27.05 million), São Paolo (22.04 million), and Mexico City (21.78 million) top the list of megacities.
