Earth population by 2020
It is believed that over time the resources of our planet will be exhausted and the inhabitants of many countries will sorely miss the most necessary. So far we are talking about food and water. Therefore, some readers are interested in what the population of the Earth will be by 2020.
Population growth dynamics
According to experts, ten thousand years ago, the population of our planet totaled five million people. At the beginning of our era, it has already reached two hundred million people. Thus, the annual population growth was approximately 0.05%.
When the industrial revolution began, the population began to grow at an unprecedented rate:
|1800 g||people living on our planet, has become one billion.|
|1930 year||in one hundred and thirty years the population has doubled.|
|1959||the next billion people appeared in about thirty years|
|1974||in fifteen years, the world's population has increased by another billion, reaching four billion.|
|1987 year||it took 13 years to increase the world's population by another billion.|
|2015||Earth's population has reached seven billion people.|
Today, the annual population growth is approximately 1.11%.
The peak of population growth was in 1963. Then it was 2.19%. Then there was a decrease in the birth rate to current levels. The planet’s population is expected to grow more slowly. For example, in 2020, growth will be at the level of 1%, in 2050 - 0.5%. Thus, in the twenty-first century the number of people will increase, but not at such a fast pace.
It is estimated that in 2020 the population growth will be 1.09%. The population in this case will be equal to: 7 758 156 792 people.
Eight billion people will become in 2025. The nine billionth barrier will be overcome in 2040. In 2056, ten billion people will live on planet Earth.
Fertility in different countries
The population of developed countries will remain virtually unchanged:
- 2010 - 1.2 billion people;
- 2020 - 1.25 billion people
The population of less developed countries will almost triple:
- 2010 - 0.8 billion people;
- 2020 - 2.5 billion people.
Thus, very soon the population of 49 backward countries will double the population of industrial powers.
The population of the most populous countries, such as: China, India, Indonesia, Brazil will increase:
- 2010 - 4.8 billion people;
- 2020 - over 6 billion people.
The share of the population of developed countries will continue to decline:
- 1950 - 32.2%;
- 2020 - 17%;
- 2050 - 13.6%.
In 2020, population growth in industrialized countries will be 0.42%. In poor countries this indicator will reach: 2.284%.
According to experts, the population growth of rich countries will stop by the middle of the century, and by the end may even take negative values. The decline in the population of developed countries will most likely be offset by migration.
The proportion of residents of backward countries will increase:
- 2013 - 12.5%,
- 2020 - 17%.
Demographic processes on the continents
During the current century, most people will live in Asia. Although, the population of Africa will continue to grow. By the end of the twenty-first century, it will reach 4.2 billion people, against the current 1.3 billion people.
More recently, sixty percent of people lived on the Asian continent. About 10% lived in Europe, and 15.5% in Africa.
Until the nineties, European countries ranked second in terms of population. In 1996, Africa surpassed Europe. The population of the African continent amounted to 734 million people, exceeding the population of Europe - 730 million people.
Currently, population growth in Africa is 2.465%. This is almost twice as much as in Asia.
The population of the African continent reached its first billion in 2009. It is planned that already in 2040 the population on the black continent will reach two billion people.
It is planned that the population of the Asian continent will grow from 4.3 to 5 billion people already in 2020.
At present, almost four times as many people live in Asia than in Africa. According to UN estimates, at the end of the century more people will live on this continent than in Africa by only 13%.
Today, the population of Europe, North and South America, as well as Oceania is 1.7 billion people. By the middle of the century, it will grow to 2 billion people. Further, this growth will slow down somewhat.
The population of Europe is now - 744 million people. According to experts, at present this continent has reached its maximum.
Fertility in South America and the Caribbean will continue. The population will reach: 792 million. already in the middle of the century.
By 2050, the world's population will be distributed approximately like this:
