Nearly 38 Million People Call This Megacity Home

"In 1950, the world was home to just under three billion people. By 1990, it had surpassed five billion. As this number now approaches eight billion, overpopulation is growing increasingly problematic."

"The matter of boundaries is particularly important to calculating GDP, and while some lists may rank New York as the largest economy among world cities, this list ranks Tokyo as the largest."

"Overpopulation in megacities brings forth a critical question: Are we pushing the Earth's resources past the point of no return, especially with U.S. citizens consuming five times more resources than sustainable?"

"By 2018, the world contained 37 megacities. Today, the count has risen to 44 according to a report from Demographia, emphasizing the continuing trend of urban population growth."
