The Growth of Human Population: Four Major Periods or Stages

An early period of hunters and gatherers  

This period ranges between the first evolutions of humans on this planet to the beginning of agriculture. During this period, it is estimated that the total population was probably less than a million, population density was about 1person per 130-260 sq km in the most habitable areas, and the Average rate of growth was perhaps less than 0.00011% per year.  

 Early, per-industrial agriculture  

This period began sometime between 9,000 BC and 6,000 BC and lasted approximately until the 16th century AD. The first major increase in population came during this period. The total human population of the world was approximately 100 million by 1AD that further increased to about 500 million by 1600 AD. The population density increased greatly to about 1 or 2 people per sq km or even more. The average rate of growth was probably about 0.03%.

The age of Industrial revolution  

The second and much more rapid increase in population started about 400 years ago with the industrial revolution associated with the advances in medicines and Health care. Experts are of the opinion that Renaissance in Europe, (beginning about 1600 AD) marks the transition from agricultural to liberate societies, when medical care and sanitation were factors responsible in reducing the death rate. The total human population of about 900 million in 1800 AD almost doubled in the next century and again doubled to approximately 3 billion by 1960. The average rate of growth by 1600 AD was about 0.1% per year, which increased about one-tenth of a percent every 50 years until 1950. The main reasons of this rapid increase in population were discovery of the causes of diseases, invention of Vaccines, improvement in sanitation, and advances in agriculture that led to a great increase in the production of food, shelter and clothing.

 

The modern era  

Though the rate of Population Growth has slowed down in developed countries, but population still continues to increase rapidly in many parts of the world, particularly developing countries. At mid 2002, the world population stood at 6.215 billion. The average rate of growth reached 2% in the middle of the 20th century and has declined to 1.3% in 2002 AD. According to projections, the global population will be Approximately 8 billion by 2025 and 10 billion by 2050 AD.  According to World Bank projections, the world population may stabilize between 10.1 to 12.5 billions. Developed countries would only increase from 1.2 billion today to 1.9 billion, but developing countries would increase from 5 billion to 9.6 billion. In these projections, the developing countries using by 95%.

Variation of Population Among Nations  

The distribution of world population densities show that while the great majority of the land surface is sparsely or moderately populated, but some limited areas are densely populated. The densely populated areas include Western Europe, the Indian subcontinent, the plains and river valleys of China, and north-eastern USA. High concentrations of people are also found in some relatively smaller areas, for example—the Nile valley of Egypt, the Islands of Java in Indonesia and the Southern part of Japan.  In terms of continents and countries, the world’s population is very ill-balanced. More than half of the world’s people live in Asia (approximately 3.7 billion), which accounts for only one-fifth of the world’s land area; while North, Central and South America together occupying more than a quarter of the land surface, have only one-fifth of the population (1.3 billion). The African continent also accounts for a quarter of the land surface but has just over one-eighth (840 million) of the world population. On the other hand, Europe whose area is only one twenty-fifth of the total has about one-ninth (729 million) of the world’s people.

The distribution within the continents is also uneven. In Asia, China alone, with about 1.29 billion people, accounts for one-third Asian and one-fifth of the world population. The Indian subcontinent has a further 1.3 billion people—India, 1.05 billion; Pakistan, 143.5 million; Bangladesh, 133.6 million; Nepal , 23.9 million; Sri Lanka , 18.9 million; Bhutan, 0.9 million; and Maldives, 0.3 million. In Europe too, the population is an evenly distributed. Far less people live in Northern European countries than in other European countries .The most populous European countries are Russia (143.5 million), Germany (82.4 million), United Kingdom (60.2 million), France (59.5 million); Italy (58.1 million), Ukraine (48.2 million), Spain (41.3 million) and Poland (38.6 million). In Africa and Americas people are for the most part spread very thinly across the land, leaving large sections such as Northern Canada, Southwest USA, the Sahara desert and the Amazon forest practically uninhabited.

The world’s population is constantly changing, and the rate of change is accelerating. In 1950, the world’s population was 2.5 billion. By 2020, it had reached 7.8 billion. And by 2050, it is projected to reach 9.7 billion.

This rapid population growth is having a profound impact on the world, and it is important to understand the factors that are driving it. One of the most important factors is the decline in mortality rates. In the past, people died at a much younger age than they do today. This was due to a number of factors, including poor sanitation, lack of access to healthcare, and high rates of infectious diseases. However, thanks to advances in medicine and public health, mortality rates have declined dramatically in recent decades. As a result, people are living longer and healthier lives.

Another factor that is driving population growth is the decline in fertility rates. In the past, Women had many more children than they do today. This was due to a number of factors, including cultural norms, economic necessity, and lack of access to contraception. However, as women have become more educated and have entered the workforce in greater numbers, they have chosen to have smaller families.

The combination of declining mortality rates and declining fertility rates is leading to a rapid increase in the world’s population. This growth is having a number of impacts on the world, including environmental, economic, and social impacts.

One of the most significant environmental impacts of population growth is the strain it is putting on natural Resources. As the population grows, so does the demand for food, water, energy, and other resources. This is leading to deforestation, Water Pollution, and Climate change.

Population growth is also having a significant economic impact. As the population grows, so does the demand for goods and Services. This is leading to economic growth, but it is also leading to increased inequality. The gap between the rich and the poor is growing, and this is leading to social unrest.

Population growth is also having a significant social impact. As the population grows, so does the demand for housing, Education, and healthcare. This is putting a strain on public services, and it is leading to overcrowding and pollution.

The rapid growth of the world’s population is a complex issue with no easy solutions. However, it is important to understand the factors that are driving it and the impacts it is having on the world. Only then can we begin to develop strategies to address the challenges it poses.

In addition to the subtopics you have listed, there are a number of other factors that can affect population growth, including:

These are just some of the factors that can affect population growth. It is important to understand these factors in order to understand the causes and consequences of population growth.

What is the population of the world?

The population of the world is currently over 7.9 billion people.

How is the population of the world distributed?

The population of the world is not evenly distributed. Asia is the most populous continent, with over 4.6 billion people. Africa is the second most populous continent, with over 1.3 billion people. Europe is the third most populous continent, with over 740 million people. North America is the fourth most populous continent, with over 330 million people. South America is the fifth most populous continent, with over 650 million people. Oceania is the least populous continent, with over 40 million people.

What are the factors that affect population growth?

The factors that affect population growth include birth rate, death rate, and migration. Birth rate is the number of births per 1,000 people per year. Death rate is the number of deaths per 1,000 people per year. Migration is the movement of people from one place to another.

What are the consequences of population growth?

The consequences of population growth include environmental problems, economic problems, and social problems. Environmental problems include deforestation, pollution, and Climate Change. Economic problems include POVERTY, Unemployment, and Inflation. Social problems include crime, violence, and overcrowding.

What are the solutions to population growth?

The solutions to population growth include family planning, education, and Economic Development. Family planning is the practice of controlling the number of children that a couple has. Education is the process of Learning and acquiring knowledge. Economic development is the process of increasing the wealth of a country.

What is the future of the world’s population?

The future of the world’s population is uncertain. Some experts believe that the population will continue to grow, while others believe that it will eventually stabilize or even decline. The factors that will affect the future of the world’s population include birth rate, death rate, migration, and economic development.
