The United Nation estimated Monday that the world's population will reach 8 billion on November 15.
In a report released on World Population Day, the U.N. also said global population growth fell below 1 per cent in 2020 for the first time since 1950.Â
According to the latest U.N. projections, the world's 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, 바카라World Population Prospects 2022,바카라 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 U.N. Population Division, said at a news conference to release the report that the date when the U.N.'s projection line crosses 8 billion is Nov. 15.
But, he noted, 바카라we do not pretend that that's the actual date 바카라Š and we think that the uncertainty is at least plus or minus a year.바카라
Nonetheless, U.N. Secretary-General Antonio Guterres called 2022 a 바카라milestone year,바카라 with 바카라the birth of the Earth's eight billionth inhabitant.바카라Â
바카라This 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,바카라 Guterres said in a statement. 바카라At 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.바카라
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 U.N. moved the date forward from 2027, especially as a result of China's 2020 census. India had been planning its census in 2021, but he said it was delayed because of the pandemic. The U.N. will reassess its projection after it takes place.
The U.N. 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.
바카라The population of 61 countries or areas are projected to decrease by 1% or more between 2022 and 2050,바카라 the report says.
바카라In 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.바카라
In other highlights, the report said global life expectancy improved almost 9 years from 1990 바카라 to 72.8 years for babies born in 2019 바카라 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's poorest countries lagged 7 years behind the global average.
As for gender balance, the report says, 바카라Globally, the world counts slightly more men (50.3%) than women (49.7%) in 2022.바카라 바카라This figure is projected to slowly invert over the course of the century," it says. 바카라By 2050, it is expected that the number of women will equal the number of men.바카라
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 바카라thanks to recent reductions in fertility,바카라 the report says.
The U.N. said this 바카라demographic dividend바카라 provides an opportunity for accelerated economic growth for those countries.
In another trend, the report said, 바카라the population above age 65 is growing more rapidly than the population below that age.바카라
바카라As a result, the share of global population at age 65 and above is projected to rise from 10% in 2022 to 16% in 2050,바카라 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 바카라will be the sole driver of population growth in high-income countries,바카라 the report said.
바카라By 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,바카라 it said.
