1. Distribution: the arrangement in space

2. Density The frequency with which something occurs in space
people per square km

3. Which has the greater population density: China or Belgium?
Arithmetic Density (“Population”): total number in an area
Which has the greater population density: China or Belgium?

4. Which has the greater population density: China or Belgium?
Pop: 1.3 billion
Pop: 10.5 million
Land: 3,705,473 sq. mi.
Land: 11,780 sq. mi.

5. Large population does not always means high density
Large population does not always means high density! Density is a factor of:
Land Area
Number of People

6. Why is this a more significant measure for Human Geography?
Physiologic Density
Why is this a more significant measure for Human Geography?
Population: million
Land Area: million sq. miles

7. Compare Australia’s arithmetic and physiological density
Physiologic Density
Compare Australia’s arithmetic and physiological density
Population: million
Land Area: million sq. miles
6% of Australia’s land area is arable
“Carrying Capacity”

8. Concentration The extent of a feature’s spread over space “Clustered”
“Dispersed”

9. Pattern Analysis: Density vs. Dispersion
