Gross Density

Urban Sprawl: This term describes when cities expand outwards, typically involving low-density residential housing. Like adding more pizzas but not necessarily more toppings or variety.

Population Distribution: Refers to how people are spread across an area, like how pizza slices might be distributed among different tables at your party.

Carrying Capacity: The maximum population size that an environment can sustain indefinitely, given available resources - akin to how many pizzas you'd need for everyone at your party to have enough.
