Human Population Peak Reached 

The world population to reach at 8 billion on November 15

According to the United Nations, the world's population will reach 8 billion on November 15, and India will overtake China as the world's most populous country the following year.

In a report released on World Population Day, the United Nations also stated that global population growth will fall below 1% in 2020 for the first time since 1950.

According to the most recent United Nations projections, the world's population could reach 8.5 billion by 2030. This figure will rise to 9.7 billion by 2050, with a peak of around 10.4 billion in the 2080s. It is expected to stay at that level until 2100.

The following are some key findings from the UN analysis:

Fertility rate drop: According to the UN, the average fertility rate was 2.3 children per woman throughout her lifetime in 2021, down from around five in 1950. The UN predicts that the number will drop to 2.1 by 2050.

"We have reached a stage in the world where the majority of countries and the majority of people are living in a country that is below replacement fertility," or roughly 2.1 children per woman, claims Snow.

Remarkable diversity: There are some significant regional disparities below the global averages. For instance, the UN predicts that by 2050, just eight nations—the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines, and Tanzania—will account for more than half of the global population growth.

According to Snow, the difference in average ages between different regions "has never been as large as it is today," with 41.7 years in Europe and 17.6 years in Sub-Saharan Africa as of the present.

These numbers might balance out, but according to Snow, "in the future, we may be closer in age, mostly old," unlike in the past when countries' average ages were mostly young.

According to some experts, these regional demographic differences could have a big impact on geopolitics in the future.

Population growth slowdown: On November 15, according to the UN Population Division, there will be eight billion people on the planet, more than three times as many as the 2.5 billion people who were counted in 1950. According to Rachel Snow of the UN Population Fund, the rate of population growth worldwide has significantly slowed down since reaching a peak in the early 1960s.

From a peak of 2.1 percent between 1962 and 1965 to less than 1 percent in 2020, annual growth has decreased. The United Nations predicts that due to a continued decline in fertility rates, that percentage may reach as low as 0.5 percent by 2050.

The UN estimates that the population will continue to increase to approximately 8.5 billion in 2030, 9.7 billion in 2050, and a peak of approximately 10.4 billion in the 2080s due to the rise in life expectancy and the number of people who are of childbearing age.

In a study published in 2020, the US-based Institute for Health Metrics and Evaluation (IHME) predicted that the world's population would peak by 2064, never exceeding 10 billion, and then decline to 8.8 billion by 2100.

India will supersede China: According to the UN, the two most populous nations, China and India, will switch places atop the podium as early as 2023, serving as another example of shifting trends. The UN predicts that China's current population of 1.4 billion people will eventually start to decline and reach 1.3 billion by 2050.

There's a possibility that China's population will only be 800 million by the end of the century. Although its fertility rate has already dropped below the replacement level, India's population, which is currently just below that of China, is projected to surpass its northern neighbor in 2023 and increase to 1.7 billion by 2050.
