The world is going to be 8 billion: it took 123 years to reach 1 to 2 billion, then 6 to 7 billion happened in just 12 years

24 hours in 1 day, 60 minutes in 1 hour, and 270 children in every minute… With this speed in the year 2023, the world population will touch the figure of 8 billion. By the way, by the beginning of the 19th century, the world population had reached 1 billion. But after just 220 years, the world population is going to be 8 billion. The world population crossed the 7 billion mark in 2011.

 

So let us tell you today on the occasion of World Population Day, 5 reasons to move towards 8 billion…

 

First reason - the high birth rate from the 18th to 20th century

 

The first reason behind this fast pace of population is the increase in the birth rate. From the 18th century to the end of the 20th century, the birth rate was very high. Till about 250 years ago, a woman gave birth to an average of 6 children. This situation persisted for one and a half hundred years. There was a slight decline in this in 1950. At that time, on average, each woman was giving birth to 5 children. Since 1950, the birth rate has fallen continuously, but in the meantime, conditions of population explosion have been created. Especially in Asia, where the population grew very rapidly in China and India. Today a woman in the world is giving birth to an average of 2.5 babies.

 

Due to the high birth rate, the world population grew rapidly after reaching 100 million in the early 19th century. It took 123 years for the world's population to reach 200 crores, in the year 1927 the world population reached the figure of 200 crores. After this, the world population reached 300 million in 1960. Once the world population crossed the 300 crore mark, after that every 100 crore population of the world went on increasing within just two decades. Through this table, understand in how many years we became a population of 8 billion.

 

The second reason- increasing life expectancy

 

250 years ago, on average, humans lived only 28 years, but today the average age has increased to more than 70 years. If we look at Life Expectancy, it is known that in the year 1770, the average age of people was only 28 years, that is, most human beings would have died in 28 years. The average age of people in the world today is 72 years. Life expectancy has been increasing all over the world since the 18th century. Today there are 30 countries where the average age of people is more than 80 and in 100 countries the average age is over 70. In India, this figure is 69.7 years. With these graphics, understand how life expectancy has increased in the world-

 

The third reason - is the steady decrease in the death rate

 

One of the major reasons for the explosive boom in the world population is the declining death rate faster than the birth rate. In fact, since 1950, there has been a steady decline in the birth rate and death rate. If we assess the figures, it is known that out of 1000 people who died in the year 1950, 20 people died, now that figure has come down to 8 in the year 2020. However, the birth rate is still much higher than the death rate. Understand the comparison between death rate and birth rate from this table-

 

The fourth reason - the lack of information among women about contraception

 

Earlier, there was very little information about contraceptives and methods of preventing pregnancy in women, due to which more children were born even if they did not want to. This is the fourth major reason for the increase in population. Talking about the progressive countries of Asia, Latin America, and Africa, in the year 1960, only 9 percent of married couples used contraception. But by the 1990s, 1 out of every 2 married couples started using contraceptives to prevent unwanted pregnancies. Today women are very aware of Contraception. According to 2015 data, 64 percent of women now use contraceptives.

 

Fifth reason - is a sharp decline in infant mortality

 

The fifth major reason for the world's population being 8 billion is the improvement in infant mortality. In the year 1990, when 93 children out of 1000 died, now this situation improved. Today it has reached the lowest level. In the year 2020, only 37 children out of 1000 died. However, the increase in the incidence of infant mortality depends greatly on the place where the child is born. Even today, 79 out of 1000 children die in sub-Saharan Africa, while the situation is not so bad in Europe and North America. Only 6 out of 1000 children die here. In Australia and New Zealand, it is number 4.

 

Why did the population increase rapidly even after the birth rate declined?

 

According to statistics, in 1951, a woman gave birth to an average of 5 children. Now in the year 2021, this figure has come down to 2.5. The birth rate has halved in the last 70 years. So now the question arises despite halving the birth rate, how did the world population grow so fast? The birth rate only tells half the story of the population. When we look at the mortality rate, we find that now every year 7.60 people die in 1000 people, while about 18 people are born per 1000 people every year. That is, the figure for the birth rate is more than 2 times the death rate. This is one of the main reasons for the increase in population.

 

India will be on top in terms of population… China's population will be reduced to half

 

In the whole world today, 270 children are born in 1 minute, which is 130 million in a year, soon the population of the whole world is going to be 8 billion, but this figure may reach 11 billion by the year 2100. It is believed that within 3-4 years India will become the most populous country in the world. At the same time, a report of the World Economic Forum has claimed that by the end of this century, the population of both India and China will decline significantly. In the year 2100, the population of India will be 1.09 billion. China will be in third place. At the same time, the population of Nigeria will be second in the world.

 

Some interesting facts related to population

 

Tokyo is the world's most populous city, with 37 million people living here, the Indian capital Delhi is second with 29 million people, while the Chinese city of Shanghai is number three where 26 million people live.

 

New Zealand has more wolves than humans, it is such a unique country in the world where more wolves are found than humans. In the year 1982, 33 lakh people used to live here, while the number of wolves was close to 7 crores. That is, 22 wolves for every 1 person, although now the population here has reached 50 lakhs and the number of wolves is 25 million, that is, still 6-7 wolves are found on 1 person.

 

Half of the world's population is young, with more than 50 percent of the world's population under 30.

 

The world population will increase by 2 billion in the next 30 years, Africa will contribute half Arab will grow further.
