Human Population Distribution And Density (Copy)
8.1 Human Population Distribution and Density – Cheat Sheet
Key Concepts
| Term | Definition | Example |
|---|---|---|
| Population Distribution | How people are spread across the Earth’s surface | Dense in South Asia; sparse in Sahara Desert |
| Population Density | Number of people per km² (population ÷ land area) | Bangladesh >1,200/km² vs Australia ~3/km² |
Global Patterns
| Region | Characteristics | Examples |
|---|---|---|
| High Density | Flat land, fertile soils, good water supply, jobs in cities | Ganges Valley (India), Yangtze Delta (China), Western Europe |
| Low Density | Harsh climates, poor soils, remote, limited resources | Sahara Desert, Arctic tundra, Amazon rainforest |
Factors Influencing Distribution
| Factor | Effect |
|---|---|
| Physical | Climate, relief, water supply, soil fertility affect where people settle |
| Economic | Availability of jobs, trade, industry attract population |
| Social/Political | Wars, stability, services (schools, hospitals) shape distribution |
Quick Pointers
- World population uneven: concentrated in Asia, Europe, coastal areas.
- Population density helps compare crowded vs sparsely populated regions.
- Influenced by physical, economic, and social factors.
