1. Distribution in Human Geography Objective: Describe how the concept of distribution is used to analyze population patterns

2. Distribution has to do with arrangement.

3. Three kinds of distribution: Density – frequency Density – frequency Concentration – spread, clustered or dispersed? Concentration – spread, clustered or dispersed? Pattern - Is there one? Pattern - Is there one?

4. Arithmetic density: people per square mile (P/A or population / area) people per square mile (P/A or population / area) A large population is not always the densest. Think: China. A smaller population could be much more dense. (Bangladesh)

6. Physiological Density Number of people per arable land; this may explain whether a country has enough food Number of people per arable land; this may explain whether a country has enough food

8. Agricultural density Number of farmers per arable land; this shows up in standard of living Number of farmers per arable land; this shows up in standard of living

9. Agricultural density

11. Concentration Clustered Dispersed

12. Concentration is not the same as density: Concentration focuses on changes in distribution Concentration focuses on changes in distribution The U.S. population has shifted from the Northeast to be more evenly dispersed across the country. The U.S. population has shifted from the Northeast to be more evenly dispersed across the country.

13. Patterns Geographers look for linear and geometric patterns. Common city grid pattern

14. Can you see a distribution pattern?

15. How is what we learned like... a kitchen item?an animal? a food item?a hobby? Arithmetic density, Agricultural density, physiological density, clustered, dispersed, patterns
