The UN says that the global population has hit eight billion, in just 11 years after crossing the seven billion mark, which is seen as a milestone in human development. The UN has also projected that after the big boom in the second half of the 20th century, population growth will begin to slow down.&nbsp;

The latest estimates by the United Nations show that the global population could grow up to 8.5 billion in 2030, 9.7 billion in 2050, and 10.4 billion in 2100. In its annual World Population Prospects report, the UN mentioned that "The world's population continues to grow, but the pace of growth is slowing down."

Population growth of any region is based on two factors, declining levels of mortality and life expectancy at birth. Globally, life expectancy has increased and reached 72.8 years in 2019, which is almost a 9-year of increment since 1990.&nbsp;On the other hand, further reductions in mortality will increase life expectancy to an average of 77.2 years globally in 2050.&nbsp;

Life expectancy at birth in males and females is taken into account separately; in 2019, female life expectancy exceeded male expectancy by 5.4 years globally. With female life expectancy standing at 73.8 years and male life expectancy at 68.4 years, female survival advantage is observed across all regions and countries.&nbsp;

The number of 8 billion may look promising but further projections by the UN shows that the global population is gradually slowing down. Though the global population took 12 years to reach 8 billion from 7 billion, it will take approximately 15 years for it to reach 9 billion.

The UN has also projected that India will surpass China as the world's most populous country in 2023. It has also been estimated that countries of sub-Saharan Africa are expected to continue to grow through 2100 and will contribute more than half of the global population increase of 2050.&nbsp;

The results of&nbsp;the UN report also show that the 46 least developed countries (LDCs) are among the world's fastest-growing unlike Latin America, Europe and Northern America, which are projected to reach their peak and then will begin to decline before 2100.

The effects of COVID-19 have also played a role in affecting components of population change, including fertility, mortality and migration. Global life expectancy at birth fell to 71.0 years in 2021 from 72.8 years in 2019, mostly due to the pandemic.

The COVID-19 pandemic has also affected many data collection processes worldwide, which is why the UN has told countries to give priority to the national censuses, as such data will be critical in development planning and achieving the Sustainable Development Goals (SDGs).

World population reaches eight billion today

Every year on the 11th of July, World Population day is celebrated. It&nbsp;is celebrated globally, so as to create awareness regarding the global population issues. Established by the United Nations Development&nbsp;Programme (UNDP)&nbsp;in 1989, people have observed World Population Day for more than 30 years.&nbsp;As overpopulation has become one of the major concerns in today's time with the world population increasing rapidly day by day, it&nbsp;is of much significance now. Family planning should be taught to people all over the world so that the rapidly increasing global population can be somewhat slowed down. Overpopulation puts pressure on the existing resources and hence it may pose problems for future generations. The UNDP aims to make people aware of all these issues that overpopulation can create. According to a report by the United Nations Population Fund, it is expected that&nbsp;the world population will hit the 8 billion mark in 2022.&nbsp;

<h2>World Population Day 2022: History and Significance&nbsp;</h2>

The United Nations Development Programme established&nbsp;World Population Day in 1989. This was done soon after the world population crossed the 5 billion mark on July 11, 1987. The United Nations also, by resolution 45/216, in&nbsp;December 1990 had decided to continue observing World Population Day in order to increase awareness&nbsp;regarding existing population issues and also their relations to the environment and development. The day holds a lot of significance because of the issue of overpopulation and hence&nbsp;it is very important to raise awareness. It&nbsp;poses a risk not only to the environment or resources, but also to the mothers and children, who may face health problems or the family may face financial problems.

<h2>What is the theme of World Population Day 2022?</h2>

The theme for this year's World Population Day is,&nbsp;"A world of 8 billion: Towards a resilient future for all – Harnessing opportunities and ensuring rights and choices for all".

The theme focuses on the problems that people are facing due to overpopulation and mentions that all the 8 billion people living in the world don't have equal rights and opportunities,&nbsp;due to overpopulation, discrimination and inequality increase. Some have access to adequate resources while some cannot even get the basic necessities like food and water. Gender-based discrimination, violence, discrimination based on class and other things are still faced by many people around the world.

<h2>World Population Day 2022: Which are the countries with the least&nbsp;population?</h2>

According to a report by Worldpopulationreview.com,&nbsp;Vatican City is the least populated country in the world, which has approximately 800 citizens. After that comes Naura which has&nbsp;10,876 citizens. Followed by this comes&nbsp;Tuvalu with a population of approximately&nbsp;11,931. Other countries that come on the list are Palau with a population of&nbsp;18,169,&nbsp;San Marino with 34,017,&nbsp;Liechtenstein with&nbsp;38,250,&nbsp;Monaco with 39,511, and&nbsp;Saint Kitts and Nevis with&nbsp;53,544.

However, the most populated country in the world is China with a population of&nbsp;1.426 billion, followed by India with a population of&nbsp;1.412 billion.&nbsp;

Not just on World Population Day, but every day, the important population issues existing nowadays should be addressed as a global issue, and people should be taught and made aware of the same. Countries with the highest population like China, India, the United States, and Indonesia should be focused on and people taught the importance of family planning.
