Population density is simply how many people are crammed into a certain space, usually a square mile or kilometer. It’s the math of “How close are my neighbors, really?” And that math can tell you everything from how long your commute will be to whether you need to fight a seagull for a parking spot.
Think of it like a party. You’ve got a small apartment (the space) and you invite five friends (the population). That’s high density—everyone’s bumping into each other, spilling dip on your couch, and someone is definitely sitting on the cat. Now imagine that same party in a football stadium. That’s low density—you’re yelling across the bleachers just to ask for the salsa.
