📖 1. Population Density and Distribution

🔑 Key Concepts & Definitions

• Population Density: The number of people living per unit area, usually expressed as people per square kilometer (people/km²). It indicates how crowded a place is.
• Population Distribution: The spatial arrangement of populations across a geographic area, showing where people live and how they are spread out.
• High Population Density: Areas with a large number of people living in a small space, such as city centers or river valleys.
• Low Population Density: Regions with few people spread over large areas, like deserts or mountain ranges.
• Clustering: The tendency of populations to concentrate in specific areas, often due to favorable conditions like resources or employment.
• Dispersal: The spread of populations across less favorable or less accessible areas.
