The world’s eight billionth resident has been born today, according to projections by the United Nations Population Division.
The global population has reached eight billion – three times the size it was in 1950 – and although there are more people on Earth than ever before because we’re living longer, population growth is at its slowest rate in more than 70 years.
In 2020 the global population growth rate fell below 1%. This is largely due to a reduced birth rate, with women having fewer children due to widespread contraception and better education and mobility for women and girls.
The global population is also getting older – 10% are aged over 65, and this will increase to 16% by 2050.
By 2050 the number of over-65s will be twice that of those under five.
Where is it growing the fastest?
The two fastest-growing regions in the world are East and Southeast Asia, home to 2.3 billion people, and central and South Asia, which has 2.1 billion people.
China and India are the joint-most populated countries in the world, with 1.4 billion people each.
Based on UN projections, India will surpass China for the first time next year.

More than half of the projected increase up to 2050 will be concentrated in eight countries: the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and Tanzania.
Countries in sub-Saharan Africa are expected to contribute more than half of the increase anticipated through 2050.
The biggest increases will come specifically from the Democratic Republic of Congo and Tanzania, with both populations doubling in the next 30 years.
Elsewhere in Africa, the biggest surges will be in Nigeria, Ethiopia and Egypt.
In Asia outside India and China, the biggest growth will happen in Pakistan and the Philippines.
More generally, 46 of the least-developed countries in the world will have the fastest-growing populations between now and 2050.
Most of this growth (two-thirds) will be driven by what has already happened – and the youthful structure of the population.

Where is the population shrinking?
The world population is growing more slowly than it has in decades due to long periods of low fertility.
More than two-thirds of people live in countries where women have 2.1 children or fewer.
This is roughly the level that would produce zero growth worldwide.
The population of 61 countries will decrease by 1% or more between now and 2050 – either due to decreased birth rates or increased levels of migration.
The war in Ukraine is having a huge impact on its population size – with projections showing it will have lost more than 20% of its population by 2050.
Four other central and eastern European countries – Bulgaria, Latvia, Lithuania and Serbia – will experience similar population decreases in the next three decades.
Overall life expectancy fell from 72.8 before the pandemic in 2019 to 71 last year.
COVID’s impact was not the same for every region, however.
Central and southern Asia, Latin America and the Caribbean were hit the most – with life expectancy decreasing by around three years.
But in Australia and New Zealand, which both shut their borders and pursued a “zero COVID” policy for most of the pandemic, life expectancy increased by 1.2 years due to a decreased risk of dying from other causes during successive lockdowns.
Coronavirus may have resulted in some short-term reductions in pregnancies, but there was no evidence of an overall decline, UN experts said.

What’s next?
The global population will continue to grow – to around 8.5 billion people by 2030 and 9.7 billion by 2050.
It will start to peak at around 10.4 billion people in the 2080s and remain at that level until 2100.
Australia, New Zealand, the rest of Oceania, North Africa and Western Asia will still be growing in population by the end of this century.
But the rest of the world, including Europe and North America, will have reached their peak and started to decline before the year 2100.
Antonio Guterres, the UN secretary-general, said of the eight billion milestone: “This is an occasion to celebrate our diversity, recognise our common humanity and marvel at advancements in health that have extended lifespans and dramatically reduced maternal and child mortality rates.”
But he added: “At 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.”
Vladimir Putin has played down the possibility of a meeting with Volodymyr Zelenskyy, saying that while it is possible, certain conditions must be met.
The Russian president was responding to an American proposal of a trilateral meeting between him, the Ukrainian president and Donald Trump.
The idea was floated by Steve Witkoff, the US president’s envoy during talks with Mr Putin on Wednesday, Kremlin aide Yuri Ushakov said.
Mr Ushakov said the three-way option was “simply mentioned by the American representative during the meeting in the Kremlin”.
He added, however: “This option was not specifically discussed.”
On the prospect of meeting Mr Zelenskyy, Vladimir Putin said: “I have already said many times that I have nothing against it in general – it is possible.”
However, he distanced himself from any such meeting happening soon, adding: “But certain conditions must be created for this. Unfortunately, we are still far from creating such conditions.”

Mr Zelenskyy offered to speak to Vladimir Putin in May, challenging him to meet in Istanbul for talks on ending the war in Ukraine – an invitation the Russian leader declined.
While a trilateral meeting appears to be off the agenda, Mr Ushakov said an agreement had been reached for Donald Trump and Vladimir Putin to meet “in the coming days”.
After the US president touted a “very good prospect” of the leaders meeting for Ukraine ceasefire talks, Mr Ushakov said on Thursday that Russian and American officials had started working on the details.
“At the suggestion of the American side, an agreement was essentially reached to hold a bilateral meeting at the highest level in the coming days,” he said.
“We are now beginning concrete preparations together with our American colleagues.”
Regarding a trilateral meeting, Mr Ushakov said: “We propose, first of all, to focus on preparing a bilateral meeting with Trump, and we consider it most important that this meeting be successful and productive.”

Will Putin agree to Trump’s condition to meet Zelenskyy?
It would be the first time the two leaders have met since Mr Trump returned to office, and follows a three-hour meeting between Mr Putin and Steve Witkoff in Moscow on Wednesday.
Following the meeting, Volodymyr Zelenskyy said it appeared that Russia was “more inclined to a ceasefire”.
The Ukrainian president said he planned to speak on Thursday to German Chancellor Friedrich Merz, as well as contacts from France and Italy.
He said he planned to discuss a ceasefire, a leaders’ summit and long-term security, adding: “Ukraine has never wanted war and will work toward peace as productively as possible.”

A poll from Gallup suggests 69% of Ukrainians support a negotiated end to the war with Russia – an almost complete reversal from 2022, when 73% favoured fighting until victory.
Most said they were sceptical the war would end soon, with 68% saying they believed it was unlikely that active fighting would stop within the next 12 months.
Staff at a zoo in Germany which culled 12 baboons and fed some of their carcasses to the lions say they have received death threats.
Tiergarten Nuremberg euthanised the healthy Guinea baboons at the end of July due to overcrowding in their enclosure.
Some remains were used for research while the rest were fed to the zoo’s carnivores.
Plans to kill the baboons were first announced last year after the population exceeded 40, and protestors gathered outside the zoo to show their outrage.
When the site closed last Tuesday to carry out the cull, several activists were arrested after climbing the fence.
The director of the zoo defended the decision, saying efforts to sterilise and rehome some baboons had failed.
“We love these animals. We want to save a species. But for the sake of the species, we have to kill individuals otherwise we are not able to keep up a population in a restricted area,” Dr Dag Encke told Sky News.

‘The staff are suffering’
He said police are investigating after he and the staff were sent death threats.
“The staff are really suffering, sorting out all these bad words, insults and threats,” Dr Encke said.
“The normal threat is ‘we will kill you, and we’ll feed you to the lions’.
“But what is really disgusting is when they say that’s worse than Dr Mengele from the National Socialists, who was one of the most cruel people in human history.
“That is really insulting all the victims of the Second World War and the Nazi regime.”
Josef Mengele was a Nazi officer who performed deadly experiments on prisoners at the Auschwitz concentration camp during the Second World War.

Zoo animals ‘treated as commodities’
Culling animals and feeding them to predators isn’t unheard of in zoos.
At the time, the zoo said it was due to a duty to avoid inbreeding.
Dr Mark Jones, a vet and head of policy at Born Free Foundation, a charity which campaigns for animals to be kept in the wild, denounced the practice and said thousands of healthy animals are being destroyed by zoos each year.
“It reflects the fact animals in zoos are often treated as commodities that are disposable or replaceable,” he said.

Zoo asks for unwanted pets
Earlier this week, a zoo in Denmark faced a backlash for asking for unwanted pets to be donated to be used as food for its predators.
In a Facebook post, Aalborg Zoo said it could take smaller live animals such as chickens, rabbits and guinea pigs, as well as horses under 147cm. It said the animals would be euthanised by specially trained staff before being fed to carnivores like the European lynx.
While some people supported the scheme, saying they had donated animals in the past, others are outraged.
“The very idea of a zoo offering to take unwanted pets in order to kill them and feed them to their predators will, I think, horrify most right-minded people,” said Dr Jones.
Aalborg Zoo has now closed the post to comments and said in a statement: “For many years at Aalborg Zoo, we have fed our carnivores with smaller livestock.
“When keeping carnivores, it is necessary to provide them with meat, preferably with fur, bones, etc., to give them as natural a diet as possible.
“Therefore, it makes sense to allow animals that need to be euthanised for various reasons to be of use in this way.
“In Denmark, this practice is common, and many of our guests and partners appreciate the opportunity to contribute.”
