4. DENSITY vs. DISTRIBUTION What factors impact how many people share one space? What might cause… …an increase in density? …a decrease ? (think indicators of development) What factors impact where a population is located within a physical region?
6. APD = average # of people /unit of land APD = Total Population Total Land Area Arithmetic population density
7. PPD = average # of people/unit of arable land ***Arable: land suitable for agricultural use PPD = Total Population Total Cultivated Area physiologicpopulation density
Density:Size of total populationTotal area of physical space sharedDistribution:Proximity to water (rivers, oceans)Along major trade/transportation routesIn areas with temperate climateProximity to natural resources
