The world’s eight billionth resident will be born today, according to projections by the United Nations Population Division.
The global population will reach 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 over 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, which is home to 2.3 billion people; and central and South Asia, which has 2.1 billion people.

Currently, China and India are the joint-most populated countries in the world, with 1.4 billion people each.
But based on UN projections, India will surpass China for the first time in 2023.

Sub-Saharan Africa is the next most-populous region, with more than 50% of population growth expected to come from there between now and 2050.
The biggest increases in growth will come specifically from the Democratic Republic of Congo and Tanzania, which will both see their populations double in the next 30 years.
Elsewhere in Africa, the biggest surges in growth will be in Nigeria, Ethiopia and Egypt.
In Asia outside of 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 current population.

Where is the population shrinking?
The world population is growing slower 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 in their lifetimes.
This is roughly the level that would produce zero growth worldwide.
Some 61 countries will see their populations decrease by 1% or more between now and 2050 – either due to decreased birth rates or increased levels of migration.

COVID decreases life expectancy
Overall life expectancy fell from 72.8 years before the pandemic in 2019 to 71 years in 2021.
COVID’s impact was not the same for every region, however.
Central and southern Asia, Latin America and the Caribbean’s life expectancies were hit the most – 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.
UN secretary-general Antonio Guterres 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.”
Donald Trump has criticised Vladimir Putin and suggested a shift in his stance towards the Russian president after a meeting with Volodymyr Zelenskyy before the Pope’s funeral.
The Ukrainian president said the one-on-one talks could prove to be “historic” after pictures showed him sitting opposite Mr Trump, around two feet apart, in the large marble hall inside St Peter’s Basilica.
The US president said he doubted his Russian counterpart’s willingness to end the war after leaving Rome after the funeral of Pope Francis at the Vatican.
In a post on his Truth Social platform, he said “there was no reason” for the Russian president “to be shooting missiles into civilian areas, cities and towns, over the last few days”.

He added: “It makes me think that maybe he doesn’t want to stop the war, he’s just tapping me along, and has to be dealt with differently, through ‘Banking’ or ‘Secondary Sanctions?’ Too many people are dying!!!”
The meeting between the US and Ukrainian leaders was their first face-to-face encounter since a very public row in the Oval Office in February.
Mr Zelenskyy said he had a good meeting with Mr Trump in which they talked about the defence of the Ukrainian people, a full and unconditional ceasefire, and a durable and lasting peace that would prevent the war restarting.
Other images released by the Ukrainian president’s office show Sir Keir Starmer and French President Emmanuel Macron were present for part of the talks, which were described as “positive” by the French presidency.
Mr Zelenskyy‘s spokesman said the meeting lasted for around 15 minutes and he and Mr Trump had agreed to hold further discussions later on Saturday.

But the US president left Rome for Washington on Air Force One soon after the funeral without any other talks having taken place.
The Ukrainian president’s office said there was no second meeting in Rome because of the tight schedule of both leaders, although he had separate discussions with Mr Starmer and Mr Macron.
The French president said in a post on X “Ukraine is ready for an unconditional ceasefire” and that a so-called coalition of the willing, led by the UK and France, would continue working to achieve a lasting peace.
There was applause from some of the other world leaders in attendance at the Vatican when Mr Zelenskyy walked out of St Peter’s Basilica after stopping in front of the pontiff’s coffin to pay his respects.

Sir Tony Brenton, the former British ambassador to Russia, said the event presents diplomatic opportunities, including the “biggest possible meeting” between Mr Trump and the Ukrainian leader.
He told Sky News it could mark “an important step” in starting the peace process between Russia and Ukraine.
Professor Father Francesco Giordano told Sky News the meeting is being called “Pope Francis’s miracle” by members of the clergy, adding: “There’s so many things that happened today – it was just overwhelming.”
The bilateral meeting comes after Mr Trump’s peace negotiator Steve Witkoff held talks with Mr Putin at the Kremlin.
They discussed “the possibility of resuming direct negotiations between Russia and Ukraine”, Kremlin aide Yuri Ushakov said.

On an extraordinary day, remarkable pictures on the margins that capture what may be a turning point for the world.
In a corner of St Peter’s Basilica before the funeral of Pope Francis, the leaders of America and Ukraine sit facing each other in two solitary chairs.
They look like confessor and sinner except we cannot tell which one is which.
In another, the Ukrainian president seems to be remonstrating with the US president. This is their first encounter since their infamous bust-up in the Oval Office.

Other pictures show the moment their French and British counterparts introduced the two men. There is a palpable sense of nervousness in the way the leaders engage.
We do not know what the two presidents said in their brief meeting.
But in the mind of the Ukrainian leader will be the knowledge President Trump has this week said America will reward Russia for its unprovoked brutal invasion of his country, under any peace deal.
Mr Trump has presented Ukraine and Russia with a proposal and ultimatum so one-sided it could have been written in the Kremlin.
Kyiv must surrender the land Russia has taken by force, Crimea forever, the rest at least for now. And it must submit to an act of extortion, a proposed deal that would hand over half its mineral wealth effectively to America.

Afterwards, Zelenskyy said it had been a good meeting that could turn out to be historic “if we reach results together”.
They had talked, he said, about the defence of Ukraine, a full and unconditional ceasefire and a durable and lasting peace that will prevent a war restarting.
The Trump peace proposal includes only unspecified security guarantees for Ukraine from countries that do not include the US. It rules out any membership of Ukraine.
Ukraine’s allies are watching closely to see if Mr Trump will apply any pressure on Vladimir Putin, let alone punish him for recent bloody attacks on Ukraine.
Or will he simply walk away if the proposal fails, blaming Ukrainian intransigence, however outrageously, before moving onto a rapprochement with Moscow.
If he does, America’s role as guarantor of international security will be seen effectively as over.
This could be the week we see the world order as we have known it since the end of the Second World War buried, as well as a pope.
Tens of thousands of people have packed St Peter’s Square as the funeral of Pope Francis begins.
Royals, world leaders and cardinals joined scores of worshippers at the Vatican, as mourning of the 266th pontiff transcended wealth and social class.
In keeping with Francis’s life as a breaker of tradition, many of the more elaborate and expensive rituals customary for the burial of popes have been foregone in favour of simpler options.
Around 200,000 people are attending the funeral, with around 50,000 packing out St Peter’s Square.

His body had been lying in state since his death aged 88 on Easter Monday, spending the last few days in St Peter’s Basilica to allow mourners to pay their respects.
The Vatican – where the funeral service is taking place – and Rome – where Francis will be laid to rest – are under heavy security, with a no-fly zone in place overhead.

Francis’s coffin has been taken out into St Peter’s Square where 220 cardinals and 750 bishops and priests are sitting in rows, waiting to say goodbye to the Bishop of Rome.
A series of readings and prayers are being read before the 50,000 faithful gathered before the basilica, and the coffin will be sprinkled with holy water and incense.

It began with Cardinal Giovanni Battista Re reading the Penitential Act – a way for the faithful to confess their sinfulness.
This was followed by the Liturgy of the Word, a part in Catholic mass where faithful gather to hear and reflect on the word of God.
Cardinal Re then delivered the homily, speaking about Pope Francis’ life and service to God.

The cardinal praised the pontiff as someone who “touched the minds and hearts of people” who was “attentive to the signs of the times”.
He added: “Despite his frailty and suffering towards the end, Pope Francis chose to follow this path of self-giving until the last day of his earthly life.”
He said Francis “was a pope among the people, with an open heart towards everyone”.

At the end of the mass, the choir will sing in Latin: “May the angels lead you into paradise; may the martyrs come and welcome you and take you into the holy city, the new and eternal Jerusalem.”
After the service, Pope Francis’s body will be taken in procession through the streets of Rome to his final resting place at his favourite church, the Basilica of Santa Maria Maggiore.

He will be ushered into the basilica – dedicated to the Virgin Mary – by prisoners and migrants, a last reflection of his priorities as pope.
In a break with tradition, the Popeoutlined in his will his request to be buried “in the ground, without particular ornamentation” but simply with the inscription “Franciscus”.
