The Earth will be home to 8.8 billion people in 2100, two billion fewer than current UN projections, says new study.

More than 20 countries, including Italy, Japan, Poland, Portugal, South Korea, Spain and Thailand, will see their numbers diminish by at least half by the year 2100, according to projections in a major study.

China’s population will fall from 1.4 billion people today to 730 million in 80 years, said the study led by an international team of researchers, published in The Lancet on Wednesday.

World’s population will continue to grow and will reach nearly 10 billion by 2050

July 23, 2019

There has been tremendous growth in the size of the world’s population in the last half century. Global population was around 3 billion in 1960. By 1987, in less than three decades, it had surpassed 5 billion and there were around 7.6 billion people in the world in 2018.

This growth varies greatly across regions. Since 1960, the largest relative growth has taken place in Sub-Saharan Africa where the population expanded from 227 million in 1960 to more than 1 billion in 2018—a nearly fivefold increase. The second largest growth over the period can be seen in Middle East and North Africa, where the population increased more than 4 times, from 105 million to 449 million.

World’s population is projected to nearly stop growing by the end of the century

July 8, 2019

For the first time in modern history, the world’s population is expected to virtually stop growing by the end of this century, due in large part to falling global fertility rates, according to a Pew Research Center analysis of new data from the United Nations.

By 2100, the world’s population is projected to reach approximately 10.9 billion, with annual growth of less than 0.1% – a steep decline from the current rate. Between 1950 and today, the world’s population grew between 1% and 2% each year, with the number of people rising from 2.5 billion to more than 7.7 billion.

As of this month, the world’s population is 7.63 billion, according to the United Nations, which celebrates World Population Day today. More than half of all people around the globe (3.97 billion) live in just seven countries, according to the UN’s estimates. China has the world’s largest population (1.42 billion), followed by India (1.35 billion). The next five most populous nations – the United States, Indonesia, Brazil, Pakistan and Nigeria – together have fewer people than India.
