Real Life Lore looked at the population density of cities around the world to calculate how large a city would need to be to hold all 7.4 billion people in the world. The hypothetical city could range in size to be as large as the continental United States or as small as Palestine depending on how densely that population lives.
What if everybody in the world, all 7.4 billion of us all lived together in the same city? How big or small would this city have to be and how close together or far apart would we all be living from each other? This video explores those concepts and visualizes what a massive global city would look like were it to ever exist in the real world.
