MailOnline's spell-binding chart tracks how the populations of the world's largest and smallest nations have dramatically shifted over time. 

India, home to 1.41billion people, pips China to top spot, with its population having tripled in size since the 60s. Over a third of the world's 8billion residents live in one of the two nations.

The US ranks a distant third at around 333million people. 

For context, that's approximately one billion fewer than 2nd-placed China, which is battling a population slump that has fuelled concerns of an impending 'disaster' for the economic superpower. 

The Pacific island of Tuvalu, meanwhile, has 124,000 times fewer people (11,312), according to World Bank data spanning 1960 to 2022. 

When the global league table of more than 200 countries is broken down, India has witnessed the largest spike in terms of raw numbers over the past decade (143million). 

China saw the second biggest jump, with a rise of 58million.

Latest UN projections, however, forecast China's population will shrink in size, even falling below 1billion before the end of the century. Births have plunged to a historic low and Beijing's efforts in recent years to encourage women to have more children have failed.

When it comes to percentage growth, however, Jordan saw the biggest jump (56.5 per cent).

Niger (46 per cent), Turks and Caicos Islands (42.5 per cent), Somalia (41.5 per cent) and Qatar (41.4 per cent) rounded out the top five. 

War-torn Ukraine, meanwhile, witnessed the most dramatic population drop, losing 7.6million between 2012 and 2022. 

Japan and Poland also saw huge falls of 2.5million and 1.2million, respectively. 

Ukraine, dragged into a war with Russia when Vladimir Putin's forces invaded Crimea in 2014, saw the third biggest percentage drop (down 16.7 per cent).

It was only beaten by the Marshall Islands (20.4 per cent) and fellow Pacific ocean nation American Samoa (17.5 per cent).  

 The data, captured by The World Bank, also saw Britain plunge from the world's ninth largest nation in 1960 to just 22nd spot by 2022.

This is despite recording a 14.6million hike in population during the same period. 

The US, meanwhile, retained third place throughout witnessing a 152.6million spike, according to the Washington-based organisation. 

Our booming global population is thanks to increasing life expectancy and decreasing mortality rate as a result of improvements in healthcare, according to the UN.

Latest data from the UN's Population Division shows global male life expectancy is predicted to be 70.8 years, with women benefiting from an additional five years at 75.6. 

In 2010, expectancy stood at just 68 and 73 years, respectively.

Women are also expected to outlive men in all regions and countries in the world, including as many as seven years in Latin America.

Latest projections by the UN suggest the world's population could grow to around 8.5billion in 2030 and 9.7billion by 2050. In November 2022 it passed the 8billion mark. 

It is the countries of sub-Saharan Africa that are expected to contribute more than half of the increase anticipated through 2050.

But despite these high fertility rates, global fertility is projected to plummet.

Alarming research last month warned that three in four countries face the threat of 'underpopulation' by 2050 because of plunging birth rates. 

By 2100 this could rise to 97 per cent of all nations, in what experts have described as a 'staggering social change'.

Powerhouses such as Britain and the US will have to become reliant on immigration to avoid 'immense' consequences, The Lancet study concluded.

In the UK, the birth rate is predicted to fall to 1.3 children per woman of childbearing age by 2100.

The rate stood at around 2.2 in the 1950s, dropping to 1.9 in the 1980s.

Currently it stands close to the 1.5 mark.

The US will see a similar downward trajectory as the UK.

Without replenishment of an ageing population, scientists claim public services and economic growth are at risk. Ever-declining birth rates will also heap extra pressure on the NHS and social care.

Commentators warned that policymakers need to 'wake up to the fact that falling fertility rates are one of the greatest threats' to the West.

Fertility replacement doesn't account for the impact of migration, meaning overall population levels can still increase in a country despite a drop in fertility rates.

The threat of underpopulation sparked by 'baby busts' has also been a pet topic of eccentric billionaire Elon Musk, who has preached about it for years.

In 2017, he said that the number of people on Earth is 'accelerating towards collapse but few seem to notice or care'.

Then in 2021 Musk, who has 11 known children, warned that civilisation is 'going to crumble' if people don't have more children.

At Italian Prime Minister Giorgia Meloni's 'Atreju' political festival in Rome in December, Musk also urged Italians to have more children to 'save Italy's culture'.

Later, he added: 'My advice to all government leaders and people is make sure you have children to create a new generation or the culture of Italy, Japan and France will disappear.' 

So what is behind the West's baby bust? 

Women worldwide, on average, are having fewer children now than previous generations.

The trend, down to increased access to education and contraception, more women taking up jobs and changing attitudes towards having children, is expected to see dozens of countries' population shrink by 2100.

Dr Jennifer Sciubba, author of 8 Billion and Counting: How Sex, Death, and Migration Shape Our World, told MailOnline that people are choosing to have smaller families and the change 'is permanent'.

'So it's wise to focus on working within this new reality rather than trying to change it,' she said.

Sex education and contraception

A rise in education and access to contraception is one reason behind the drop off in the global fertility rate.

Education around pregnancy and contraception has increased, with sex education classes beginning in the US in the 1970s and becoming compulsory in the UK in the 1990s.

'There is an old adage that 'education is the best contraception' and I think that is relevant' for explaining the decline in birth rates, said Professor Allan Pacey, an andrologist at the University of Sheffield and former chair of the British Fertility Society.

Elina Pradhan, a senior health specialist at the World Bank, suggests that more educated women choose to have fewer children due to concerns about earning less when taking time off before and after giving birth.

In the UK, three in 10 mothers and one in 20 fathers report having to cut back on their working hours due to childcare, according to ONS data.

They may also have more exposure to different ideas on family sizes through school and connections they make during their education, encouraging them to think more critically about the number of children they want, she said.

And more educated women may know more about prenatal care and child health and may have more access to healthcare, Ms Pradhan added.

Professor Jonathan Portes, an economist at King's College London, said that women's greater control over their own fertility means 'households, and women in particular, both want fewer children and are able to do so'.

More women entering the workplace

More women are in the workplace now than they were 50 years ago — 72 vs 52 per cent — which has contributed to the global fertility rate halving over the same time period.

Professor Portes also noted that the drop-off in the birth rate may also be down to the structure of labour and housing markets, expensive childcare and gender roles making it difficult for many women to combine career aspirations with having a family.

The UK Government has 'implemented the most anti-family policies of any Government in living memory' by cutting services that support families, along with benefit cuts that 'deliberately punish low-income families with children', he added.

As more women have entered the workplace, the age they are starting a family has been pushed back. Data from the ONS shows that the most common age for a women who were born in 1949 to give birth was 22. But women born in 1975, were most likely to have children when they were 31-years-old.

In another sign that late motherhood is on the rise, half of women born in 1990, the most recent cohort to reach 30-years-old, remained childless at 30 — the highest rate recorded.

Women repeatedly point to work-related reasons for putting off having children, with surveys finding that most women want to make their way further up the career ladder before conceiving.

However, the move could be leading to women having fewer children than they planned. In the 1990s, just 6,700 cycles of IVF — a technique to help people with fertility problems to have a baby — took place in the UK annually. But this skyrocketed to more than 69,000 by 2019, suggesting more women are struggling to conceive naturally.

Declining sperm counts

Reproductive experts have also raised the alarm that biological factors, such as falling sperm counts and changes to sexual development, could 'threaten human survival'.

Dr Shanna Swan, an epidemiologist at Icahn School of Medicine at Mount Sinai in New York City, authored a ground-breaking 2017 study that revealed that global sperm counts have dropped by more than half over the past four decades.

She warned that 'everywhere chemicals', such as phthalates found in toiletries, food packaging and children's toys, are to blame. The chemicals cause hormonal imbalance which can trigger 'reproductive havoc', she said.

Factors including smoking tobacco and marijuana and rising obesity rates may also play a role, Dr Swan said.

Studies have also pointed to air pollution for dropping fertility rates, suggesting it triggers inflammation which can damage egg and sperm production.

However, Professor Pacey, a sperm quality and fertility expert, said: 'I really don't think that any changes in sperm quality are responsible for the decline in birth rates.

'In fact, I do not believe the current evidence that sperm quality has declined.'

He said: 'I think a much bigger issue for falling birth rates is the fact that: (a) people are choosing to have fewer children; and (b) they are waiting until they are older to have them.'

Fears about bringing children into the world

Choosing not to have children is cited by some scientists as the best thing a person can do for the planet, compared to cutting energy use, travel and making food choices based on their carbon footprint.

Scientists at Oregon State University calculated that the each child adds about 9,441 metric tons of carbon dioxide to the 'carbon legacy' of a woman. Each metric ton is equivalent to driving around the world's circumference.

Experts say the data is discouraging the climate conscious from having babies, while others are opting-out of children due to fears around the world they will grow up in.

Dr Britt Wray, a human and planetary health fellow at Stanford University, said the drop-off in fertility rates was due to a 'fear of a degraded future due to climate change'.

She was one of the authors behind a Lancet study of 10,000 volunteers, which revealed four in ten young people fear bringing children into the world because of climate concerns.

Professor David Coleman, emeritus professor of demography at Oxford University, told MailOnline that peoples' decision not to have children is 'understandable' due to poor conditions, such as climate change.
