The world's population has reached 8 billion today, will India overtake China in 2023?

The population of the world has reached 8 billion today (November 15). According to the United Nations report, new estimates have shown that by 2030 the global population will reach around 8.5 billion. The United Nations has also projected the world population to be 9.7 billion by 2050 and 10.4 billion by 2100. Increase in birth rate is being seen mostly in those countries where per capita income is very low.

According to this calculation of the United Nations, in 2023, India will have another achievement in its hands and the country will become the most populous country in the world leaving behind China. At present, the population of China is 1.44 billion and that of India is 1.39 billion. These are the two most populous countries in the world.

But, it is a matter of concern that for the first time since 1950, such a period has come when the pace of population growth has slowed down. The rate of population growth in 2020 has been less than 1 percent. According to this estimate of the UN, which came out in 2022 regarding the population, there has been a rapid decline in fertility in many countries in the last few decades. Two-thirds of the world's population lives in areas where the female fertility rate is less than 2.1 percent.

Population growth rate will be less than 1% in 61 countries

It took 12 years for the world population to increase from 7 billion to 8 billion. But now it will take about 15 years to reach 8 billion to 9 billion. This shows that the rate of population growth in the world is decreasing. According to the United Nations, between 2022 and 2050, the population of 61 countries or territories is estimated to decrease by 1 percent. The reason for this is being said to be the continuous decrease in fertility and in some cases the compulsion of migrant life.

Important contribution of India-China population

The population of both countries is estimated to be more than 1.4 billion. By 2050, the focus of the increase in the world's population will be on 8 countries. This includes India, Pakistan, Congo, Egypt, Ethiopia, Nigeria, Philippines and Tanzania.

The decline in the death rate also increases

Population growth occurs partly when there is a decline in the death rate. Globally, the death rate has also declined. According to the 2019 census, the world's average mortality rate is 72.8 years. Since 1990, there has been an increase of about 9 years. By 2050, it may reach around 77.2 years. That is, in the coming time, the death rate will decrease further and the average age of the person will increase.

Rapid population growth in poor countries

If we look at the global population statistics, the rate of population growth has increased in poor countries. Most of them are countries in sub-Saharan Africa. According to the United Nations, it is necessary to meet the objectives of the Paris Agreement to stop the increase in global temperature. In this it is necessary to balance the Sustainable Development Goals and the goal of production as well as consumption. Reducing the rate of population growth can also help in reducing the damage done to the environment faster.
