The document discusses key concepts in population geography, including population distribution, density, and growth rates around the world. It notes that over half of the world's population lives in East, South, and Southeast Asia despite these regions making up under 10% of the world's total land area. Birth and death rates vary significantly between regions and are linked to factors like modernization and development. Exponential population growth has led to shorter doubling times in recent decades.

2. Population Geography: Essential Questions Where is the world's population distributed? Where has the world's population increased? Why is population increasing at different rates in different countries? Why might the world face an overpopulation problem? 10/03/11

3. Population Geography Density refers to the frequency with which something occurs Distribution refers to the arrangement of a feature in space 10/03/11

4. Population Density a measure of the number of people per unit area of land arithmetic: people per unit area of land physiologic: people supported by arable land agricultural: farmers to amount of arable land 10/03/11

9. Bangladesh Population: 144,000,000 Area: 144,000 sq miles 62% arable land (89,280 sq miles) physiologic density=1612 people per square mile of arable land 10/03/11

10. Montana/United States Montana Population: 145,000 Area: 902,195 square miles 18% arable land = 162,395 square miles Physiologic density = 1119 per square mile US Population: 300,000,000 Area: 3,717,810 square miles 19% arable land = 706,383 square miles Physiologic density = 424 per square mile 10/03/11

11. World Population Concentrations East Asia South Asia Southeast Asia Europe 10/03/11 In the three Asian clusters, more than ½ the world’s population lives on less than 10% of the world’s land.

13. East Asia China, Korea, Japan, Taiwan 1/5 the world’s total population 5/6 of the region’s population live in China, mostly river and coastal regions 2/3 of people in China live as farmers in rural areas In Japan and Korean Peninsula, ¾+ live in urban areas and work in industry and service 10/03/11

14. South Asia India, Pakistan, Bangladesh, Sri Lanka 1/5 the world’s population most are rural farmers (3/4), not city dwellers centered along Ganges and Indus river valleys, lowlands and coastal areas restrained by mountains 10/03/11

15. Southeast Asia Indonesia, Papua New Guinea, Philippines Island nations in the Pacific Around river valleys and deltas 10/03/11

16. Europe Britain, Germany, Poland, Ukraine, Belarus, France, N Italy ¾ live in cities Less than 20% are farmers Highest concentration near coal fields 10/03/11
