India is the second most populous country in the world next only to China. On March 1, 2011 the total Population of India was at 1.247 billion. This accounted for 17.5% of the world’s total population. In other words, about every sixth person in the world there is an Indian. China, the most populous country of the world, is a step ahead of us as every fifth person in the world there is a Chinese. While India possesses only 2.42% of the world’s total land area, she is required to sustain almost 17.5% of the world’s population.
Two components of population Growth are: Natural growth: It is analysed by assessing the crude birth and death rates. Induced growth: It is assessed by the volume of inward and outward movement of people in any given area. There are four phases of Population Growth in India. The period from 1901-1921 is referred to as a period of stagnant growth of India’s population. The high birth rate was counterbalanced by high death rate. The decades 1921-1951 are referred to as the period of steady population growth. The mortality rate started showing downward trend as a result of improvement in general Health and sanitation conditions after 1921.
The density of population is expressed as the number of persons per square kilometre. According to 2011 census, the density of population in India is 382 persons per square kilometre. Over the last 100 years density has increased more than four times.
Density and its variation across states can be accessed by the following table:-

Population growth is the increase in the number of people in a population. Global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billion in 2022. It is expected to keep growing, although predictions differ as to when and if this growth will plateau.
There are two main components of population growth: natural increase and net Migration. Natural increase is the difference between the birth rate and the death rate. Net migration is the difference between the number of people immigrating to a country and the number of people emigrating from a country.
Population distribution is the pattern of how people are spread out over the Earth’s surface. It is affected by a number of factors, including Climate, Landform, and Resources. Population distribution is also affected by human activities, such as Urbanization and ruralization.
Urbanization is the process of people moving from rural areas to cities. Ruralization is the process of people moving from cities to rural areas. Urbanization is a global trend, with more and more people living in cities. In 2020, for the first time in history, more people lived in urban areas than in rural areas.
Population density is the number of people living in a given area. It is calculated by dividing the population by the area. Population density can be expressed in absolute terms, such as people per square kilometer, or in relative terms, such as people per square kilometer of arable land.
Population density has a number of implications for resources, Environment, health, and social issues. For example, high population density can put a strain on resources, such as water and food. It can also lead to environmental problems, such as pollution and deforestation. High population density can also have a negative impact on health, as it can increase the spread of diseases. Finally, high population density can lead to social problems, such as crime and POVERTY.
In conclusion, population growth, distribution, and density are all important issues that affect the world today. These issues are complex and there are no easy solutions. However, it is important to understand these issues in order to address them effectively.
Here are some additional details on each of the subtopics:
- Population growth: The global human population has grown from 1 billion in 1800 to 7.9 billion in 2022. It is expected to keep growing, although predictions differ as to when and if this growth will plateau. The main factors driving population growth are declining death rates and increasing life expectancy.
- Population distribution: Population distribution is the pattern of how people are spread out over the Earth’s surface. It is affected by a number of factors, including climate, landform, and resources. Population distribution is also affected by human activities, such as urbanization and ruralization. The most populous regions in the world are Asia and Africa.
- Population density: Population density is the number of people living in a given area. It is calculated by dividing the population by the area. Population density can be expressed in absolute terms, such as people per square kilometer, or in relative terms, such as people per square kilometer of arable land. The most densely populated regions in the world are East Asia and South Asia.
- Population density and resources: High population density can put a strain on resources, such as water and food. It can also lead to environmental problems, such as pollution and deforestation. For example, in some parts of the world, the demand for water is outstripping the supply. This is leading to water shortages, which can have a devastating impact on people’s lives.
- Population density and environment: High population density can also lead to environmental problems, such as pollution and deforestation. For example, in some parts of the world, the demand for land is leading to deforestation. This is having a negative impact on the environment, as it is destroying forests that play an important role in absorbing carbon dioxide from the Atmosphere.
- Population density and health: High population density can also have a negative impact on health, as it can increase the spread of diseases. For example, in some parts of the world, the lack of sanitation and clean water is leading to the spread of diseases such as cholera and typhoid.
- Population density and social issues: High population density can also lead to social problems, such as crime and poverty. For example, in some parts of the world, the high cost of living is leading to an increase in crime. This is having a negative impact on people’s lives, as they are less safe and have less Money to spend on basic necessities.
What is the world population?
The world population is the total number of humans currently living on Earth. As of February 2023, it is estimated to be 8 billion people.
How is the world population distributed?
The world population is not evenly distributed. The majority of the world’s population lives in Asia, followed by Africa and Europe. North America, South America, and Oceania have much smaller populations.
What is the population density of the world?
The population density of the world is the average number of people per square kilometer. The world’s population density is 55 people per square kilometer. However, this number varies greatly from region to region. For example, the population density of Europe is 138 people per square kilometer, while the population density of Africa is 49 people per square kilometer.
What are the causes of population growth?
There are a number of factors that contribute to population growth. These include:
- High birth rates: In many parts of the world, the birth rate is still high. This means that there are more births than deaths, which leads to population growth.
- Low death rates: In recent years, death rates have declined in many parts of the world. This is due to improvements in healthcare and living standards. As a result, there are fewer deaths, which also leads to population growth.
- Migration: Migration can also contribute to population growth. When people move from one country to another, they can bring their children with them. This can lead to an increase in the population of the destination country.
What are the effects of population growth?
Population growth can have a number of effects on Society and the environment. These include:
- Increased demand for resources: As the population grows, there is an increased demand for resources such as food, water, and energy. This can put a strain on the environment and lead to shortages.
- Increased pollution: Population growth can also lead to increased pollution. This is because more people produce more waste, which can pollute the air, water, and land.
- Social problems: Population growth can also lead to social problems such as crime, poverty, and Unemployment. This is because there are more people competing for limited resources.
What are the solutions to population growth?
There are a number of solutions to population growth. These include:
- Investing in Education: Education can help people to make informed decisions about family planning. This can lead to lower birth rates.
- Providing access to contraception: Contraception can help people to control their fertility. This can also lead to lower birth rates.
- Promoting Equality/”>Gender Equality: Gender equality can help to reduce poverty and improve access to education and healthcare. This can also lead to lower birth rates.
- Addressing the root causes of migration: Addressing the root causes of migration can help to reduce the number of people who move from one country to another. This can also help to reduce population growth.
What is the future of population growth?
The future of population growth is uncertain. The United Nations estimates that the world population will reach 9.7 billion by 2050. However, this number could be higher or lower depending on a number of factors, such as the rate of Economic Development, the availability of resources, and the effectiveness of population control measures.
