The section explains the concept of population density, its average figures globally and in specific regions, and factors that affect population distribution, such as geographical, social, cultural, and economic influences. It also elaborates on the characteristics of densely and sparsely populated areas.
This section explores the concept of population density, defined as the number of people living in a unit area, typically expressed per square kilometer. Globally, the average density is approximately 51 persons per square kilometer, while India has a significantly higher average density of 382 persons per square kilometer.
It highlights that the distribution of population is not uniform—more than 90% of the world's population is concentrated on about 30% of the land area. Key factors affecting population density include geographical considerations such as topography (with plains being preferred for habitation), climate (extreme conditions deter settlement), and the availability of resources like water and fertile soil. Moreover, socio-economic factors such as housing, education, and employment opportunities play a crucial role in influencing where people choose to live. The section emphasizes the importance of understanding these dynamics for planning and resource management as population density directly impacts sustainability and development.
Population Density: Measurement of how crowded an area is based on the number of people per square kilometer.
Distribution of Population: The global imbalance in where people live, with certain areas being densely populated while others are sparsely populated.
Factors Influencing Population: Elements such as geography, climate, resources, and socio-economic conditions that affect where populations settle.
Dense and crowded, that’s the game, Population density is its name!
Imagine a boat on a river; it’s overcrowded at one end and empty at the other. That’s like population density! Some spots are bustling with life, while others are quiet.
G.W.E.S. helps to remember the factors affecting density: Geography, Weather, Economy, Social factors.
Example 1: South and Southeast Asia are some of the most densely populated regions due to favorable climate and agricultural conditions.
Example 2: The Sahara Desert is sparsely populated because of its extreme climate and lack of water resources.
