Definition of Density of Population

Unlock Audio Book

Signup and Enroll to the course for listening the Audio Book

Density of population is expressed as number of persons per unit area. It helps in getting a better understanding of the spatial distribution of population in relation to land.

Detailed Explanation

Density of population is a measure of how many people live in a specific area, usually calculated per square kilometer. This metric helps to understand how populated different regions are, allowing for comparisons between areas. For instance, if a city has a high population density, it means there's a large number of people living in a relatively small space, leading to crowded conditions, while a sparsely populated area might have a more relaxed atmosphere.

Examples & Analogies

Think of it like a party at a home. If you have 100 people in a small living room, it's very crowded (high density). If you have the same number of people in a large backyard, it feels spacious (low density).

Current Density Statistics in India

The density of population in India (2011) is 382 persons per sq km. There has been a steady increase of more than 200 persons per sq km over the last 50 years as the density of population increased from 117 persons/ sq km in 1951 to 382 persons/sq km in 2011.

Detailed Explanation

As of the 2011 Census, India has a population density of 382 individuals for every square kilometer. This statistic reflects an increase in population density over time; in 1951, the density was only 117 persons per square kilometer. The continued rise indicates not just an increase in population, but possibly a trend towards more people living in urban areas, where space is limited.

Examples & Analogies

This can be compared to a school classroom. If the classroom has 20 desks but now fits 30 students, it's crowded. Over time, if more students keep coming, the school needs to find either larger classrooms or create more classes. Similarly, India is experiencing growing numbers of people in limited space.

Spatial Variation of Population Density

The data shown in Appendix (i) give an idea of spatial variation of population densities in the country which ranges from as low as 17 persons per sq km in Arunachal Pradesh to 11,297 persons in the National Capital Territory of Delhi.

Detailed Explanation

Population density varies significantly across India. For example, Arunachal Pradesh has one of the lowest population densities with only 17 individuals per square kilometer due to its hilly terrain and remote location, while Delhi, being a bustling metropolis, has a staggering density of 11,297 people per square kilometer. This stark difference is primarily due to geographic, economic, and infrastructural factors, which influence migration, settlement patterns, and resource availability.

Examples & Analogies

Imagine a vast wild area like a national park, which has very few visitors compared to a concert venue filled to capacity. People tend to gather in places that offer resources or opportunities, which explains why cities are more densely populated than remote wilderness areas.

Factors Influencing Population Density

Such an uneven spatial distribution of population in India suggests a close relationship between population and physical, socio-economic and historical factors. Physical factors such as climate, terrain, and the availability of water largely determine the pattern of the population distribution.

Detailed Explanation

Population density is influenced by a variety of factors. Physical characteristics of a region, such as climate and terrain, play a crucial role. For instance, fertile plains might support larger populations since they can sustain agriculture, while mountainous or arid regions may be underpopulated due to harsh living conditions. Socio-economic elements like job opportunities, healthcare, and education systems also draw people into densely populated areas.

Examples & Analogies

Consider a farm: if one field has exceptional soil and is close to a water source, farmers will flock there to grow crops, while barren land far from water remains empty. The location's attractiveness determines how many people settle in that area.

Population Density and Economic Development

Regions falling in the river plains and coastal areas of India have remained regions of larger population concentration. Even though the uses of natural resources like land and water in these regions have shown signs of degradation, the concentration of population remains high because of early human settlement.

Detailed Explanation

Areas such as river plains and coastal regions have historically supported larger populations. These regions offer natural resources like fertile soil and access to water, which have enabled agriculture and trade. Despite challenges like resource degradation, people continue to inhabit these areas due to existing infrastructure and economic opportunities, illustrating how economic development can attract population growth.

Examples & Analogies

Think of a city that was once thriving due to a factory. Even if the factory is running low on materials, people will often stay because their jobs, homes, and communities are established there. The familiarity and conveniences keep them from moving away.

Understanding Physiological and Agricultural Density

Unlock Audio Book

Signup and Enroll to the course for listening the Audio Book

To get a better insight into the human-land ratio in terms of pressure of population on total cultivable land, the physiological and agricultural densities should be calculated.

Detailed Explanation

Physiological density measures the number of people per unit of cultivated land, while agricultural density measures how many agricultural workers exist per unit of arable land. These metrics provide deeper insight into how population pressures affect land usage and resource allocation, important for understanding agricultural productivity and sustainability.

Examples & Analogies

Imagine a pizza: if it's cut into small slices but too many people want a piece, tension can arise over who gets what. Similarly, if too many people rely on a limited amount of farmland, it can lead to conflicts over resources, unsustainable farming practices, and food shortages.
