5.2. Distribution of Population

The way in which people are spread across the earth's surface is known as the pattern of population distribution. More than 90 per cent of the world’s population lives in about 30 per cent of the land surface. The distribution of population in the world is extremely uneven.

Population distribution refers to how people are spread out across the planet. It's important to note that while the Earth has a vast land area, most of the population is concentrated in specific regions. In fact, over 90% of people live on only 30% of the land. This means that some areas are very crowded, while others have very few people. Understanding this distribution helps us grasp where resources and services are needed the most.

Think of a small pie cut into many pieces. If most of the guests at a party only eat from the small section of the pie, that part becomes empty quickly, while other parts remain full. Similarly, in terms of population, some regions (like urban areas) 'get eaten up' by high population density, leaving vast areas (like deserts) much less populated.

Some areas are very crowded and some are sparely populated. The crowded areas are South and Southeast Asia, Europe, and northeastern North America. Very few people live in high latitude areas, tropical deserts, high mountains, and areas of equatorial forests.

Around the world, some regions have a high density of people, meaning there are many people living in a small area. For example, South and Southeast Asia, parts of Europe, and northeastern North America are known for having a lot of people in them. In contrast, extreme environments such as deserts, high mountains, and forests near the equator contain very few inhabitants. Understanding these patterns helps in planning infrastructure, services, and resources in urban areas versus rural or uninhabitable areas.

Imagine a classroom filled with students. On a test day, some kids sit closer to the front and are surrounded by friends, while others sit at the back, spread out and lonely. The front row can be compared to densely populated areas, where people are close together, while the back row is like the sparsely populated regions.

Many more people live north of the Equator than south of the Equator. Almost three-quarters of the world’s people live in two continents: Asia and Africa. Sixty per cent of the world’s people stay in just 10 countries. All of them have more than 100 million people.

The geographic distribution of the population indicates where people live in relation to the Equator. Notably, the majority of the global population resides in the Northern Hemisphere, specifically in regions like Asia and Africa. Interestingly, 60% of people live in just 10 countries, all of which have populations exceeding 100 million. This concentration illustrates the significant disparities in population density across different nations.

Take a world map, and if you color in the countries with the most people, you would notice that Southeast Asia has a lot of bright colors while South America might have only a few. It’s like a pizza where most of the toppings are concentrated on one half but not the other, showcasing how unevenly spread the population is.

Factors such as geography, climate, soil fertility, and availability of resources significantly affect how population is distributed. Areas with favorable conditions such as good climate, fertile soil, and access to water sources tend to be more densely populated.

Geographic and environmental factors play a critical role in shaping population distribution. Regions that are flat, have a mild climate, fertile soil, and ample fresh water are more likely to attract people. Conversely, harsh climates, rough terrains, and lack of resources result in lower populations. Recognizing these factors helps researchers and policymakers understand and manage human settlements.

Think about a camping trip. You and your friends would prefer a flat area with trees for shade and a water source nearby rather than camping on a rocky mountain or in an arid desert. Similarly, people are drawn to areas where the environment supports life and economic activities.
