UNITED NATIONS -

The United Nations estimated Monday that the world鈥檚 population will reach 8 billion on Nov. 15 and that India will replace China as the world鈥檚 most populous nation next year.

In a report released on World Population Day, the UN also said global population growth fell below 1% in 2020 for the first time since 1950.

According to the latest UN projections, the world鈥檚 population could grow to around 8.5 billion in 2030, 9.7 billion in 2050 and a peak of around 10.4 billion during the 2080s. It is forecast to remain at that level until 2100.

The report says more than half the projected increase in population up to 2050 will be concentrated in just eight countries: Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and Tanzania.

The report, 鈥淲orld Population Prospects 2022,鈥 puts the world's population at 7.942 billion now and forecasts it will reach 8 billion in mid-November.

John Wilmoth, director of the UN Population Division, said at a news conference to release the report that the date when the UN鈥檚 projection line crosses 8 billion is Nov. 15.

But, he noted, 鈥渨e do not pretend that that鈥檚 the actual date 鈥 and we think that the uncertainty is at least plus or minus a year.鈥

Nonetheless, UN Secretary-General Antonio Guterres called 2022 a 鈥渕ilestone year,鈥 with 鈥渢he birth of the Earth鈥檚 eight billionth inhabitant.鈥

鈥淭his is an occasion to celebrate our diversity, recognize our common humanity, and marvel at advancements in health that have extended lifespans and dramatically reduced maternal and child mortality rates,鈥 Guterres said in a statement. 鈥淎t the same time, it is a reminder of our shared responsibility to care for our planet and a moment to reflect on where we still fall short of our commitments to one another.鈥

The report projects that next year India, with a current population of 1.412 billion, will surpass China, with a current population of 1.426 billion, but Wilmoth said there is more uncertainty about that date than the Earth reaching 8 billion inhabitants on Nov. 15.

Wilmoth said the UN moved the date forward from 2027, especially as a result of China鈥檚 2020 census. India had been planning its census in 2021, but he said it was delayed because of the pandemic. The UN will reassess its projection after it takes place.

The UN projects that in 2050 the United States will remain the third most populous country in the world, behind India and China. Nigeria is projected to be No. 4, followed by Pakistan, Indonesia, Brazil, Congo, Ethiopia and Bangladesh. Russia and Mexico, which are in the top 10 most populous countries in 2022, are projected to lose their ninth and 10th spots in 2050.

鈥淭he population of 61 countries or areas are projected to decrease by 1% or more between 2022 and 2050,鈥 the report says.

鈥淚n countries with at least half a million population, the largest relative reductions in population size over that period, with losses of 20% or more, are expected to take place in Bulgaria, Latvia, Lithuania, Serbia and Ukraine.鈥

In other highlights, the report said global life expectancy improved almost 9 years from 1990 鈥 to 72.8 years for babies born in 2019 鈥 and is projected to reach 77.2 years in 2050 as death rates continue to decrease. But in 2021, it said, life expectancy in the world鈥檚 poorest countries lagged 7 years behind the global average.

As for gender balance, the report says, 鈥淕lobally, the world counts slightly more men (50.3%) than women (49.7%) in 2022.鈥 鈥淭his figure is projected to slowly invert over the course of the century," it says. 鈥淏y 2050, it is expected that the number of women will equal the number of men.鈥

The share of working age people between ages 25 and 64 has been increasing in most countries of sub-Saharan Africa, parts of Asia and in Latin America and the Caribbean 鈥渢hanks to recent reductions in fertility,鈥 the report says.

The UN said this 鈥渄emographic dividend鈥 provides an opportunity for accelerated economic growth for those countries.

In another trend, the report said, 鈥渢he population above age 65 is growing more rapidly than the population below that age.鈥

鈥淎s a result, the share of global population at age 65 and above is projected to rise from 10% in 2022 to 16% in 2050,鈥 it said.

Wilmoth said high life expectancy and very low levels of fertility and birth rates in European countries, Japan, North America, Australia and New Zealand are driving the tendency toward rapid population aging, and eventually potential population declines.

As a result, over the next few decades, international migration 鈥渨ill be the sole driver of population growth in high-income countries,鈥 the report said.

鈥淏y contrast, for the foreseeable future, population increase in low-income and lower-middle-income countries will continue to be driven by an excess of births over deaths,鈥 it said.
