The planet's mega-moneyed are scattered far and wide, with 78 nations and territories across four continents all boasting at least one billionaire.
That said, the richest individual's net worth varies wildly from country to country. The wealthiest residents of Portugal and Poland, for example, own nearly 50 times less wealth than that of the global number one.
Read on to find out who rules the roost in the world's biggest economies based on the latest data from Forbes as of 3 May 2024, except where otherwise stated.
All dollar amounts in US dollars.
Pham Nhat Vuong is the richest man in Vietnam with a fortune of $4.3 billion (£3.4bn). The businessman got his start when he created a popular instant noodle business while studying in Russia in the 1990s.
Today he's the chairman of Vingroup, Vietnam's largest conglomerate, which has holdings in real estate, retail and healthcare.
The only billionaire in Portugal is Maria Fernanda Amorim, the widow of Americo Amorim (the couple are pictured here). She and their three daughters inherited his fortune when he passed away in 2017.
Americo oversaw his family's cork business, Corticeira Amorim, which dates back to 1870 and has dominated the industry. He also invested in banks in several countries and held an estimated 18% stake in Portuguese oil and gas company Galp Energia, currently chaired by his eldest daughter, Paula Amorim.
Poland is home to nine billionaires, and Michał Sołowow is the official top dog with a net worth of $6.7 billion (£5.4bn).
The savvy investor started his career at construction firm Mitex in the late 1980s before selling the company in 2002. He channelled the proceeds from the sale into the Polish stock market, mopping up huge stakes in successful companies such as chemicals giant Synthos and biotech firm OncoaArendi.
Ivar Tollefsen, the richest of Norway's 12 billionaires with a $7.8 billion (£6.2bn) net worth, started his DJ and events company at the age of 14.
He used the profits from his first venture to build a real estate empire called Fredensborg AS, which currently owns 100,000 apartments across Europe. The self-made billionaire is also something of an adventurer. In 2016 he set a new world record for the fastest crossing of Greenland on skis, and in 2009 he competed in the Dakar rally.
The richest person in Belgium is old-money sugar baron Éric Wittouck, whose grandfather Paul and great-uncle Frantz (pictured) established the Tiense Suicker company at the end of the 19th century.
Publicity-shy Wittouck has massively expanded his fortune with the help of US private equity firm Invus, which has made several lucrative investments on his behalf in companies such as WW International (formerly known as Weight Watchers) and Blue Buffalo Pet Products.
Since the deaths of his father and brother in 2022, Shapoor Mistry has controlled the 157-year-old Indian engineering and construction company Shapoorji Pallonji Group.

The richest of South Africa's six billionaires is Johann Rupert. He's the chairman of Swiss luxury goods firm Compagnie Financiere Richemont, a holding company that counts Cartier and Montblanc among its portfolio.

While New Zealand is fast becoming a magnet for super-rich doomsday preppers, the country is home to just four people with a net worth in excess of 10 figures: Lord of the Rings director Peter Jackson, investor Richard Chandler, tech whizz Charles Gibbons, and packaging tycoon Graeme Hart.
With a fortune of $10.6 billion (£8.5bn), Auckland resident Hart is the wealthiest of the trio by a long stretch. He's not afraid to splash the cash either, and in 2023 he reportedly took delivery of a swish new superyacht featuring a helipad and incredible glass stairways.
South Korea's wealthiest individual leads its biggest and most successful conglomerate.
Despite serving time in prison for bribery and embezzlement, Samsung Electronics vice chairman Jay Y Lee remains at the top of the globally renowned business and has held on to his substantial $10.6 billion (£8.5bn) fortune in the process.
Manuel Villar's self-made fortune of $11.4 billion (£9.1bn) puts him ahead of the 12 other billionaires in the Philippines, and his wealth comes from a diverse range of companies. These include property development firm Vista Land & Lifescapes, run by his son Manuel Paolo, which includes a portfolio of 10 shopping malls and two office towers.
Villar's wife and other children hold public office, and he too has been actively involved in politics, even running for president in 2010. In recent years he's been bust launching his own TV network.
Robert Kuok (pictured centre) is the richest person in Malaysia with a $12 billion (£9.6bn) fortune.
His wealth is diversified across several industries.

The successful and long-established business magnate celebrated his 100th birthday in October 2023.

Povlsen's parents started the family business in 1975, and its subsidiaries include the clothing brands Jack&Jones, Only, and Vero Moda. Taking over the company at 28, the businessman has gone on to invest in online retailer ASOS, grocer Nemlig, and payments firm Klarna.
Thailand's richest billionaire is Dhanin Chearavanont, chairman of the Charoen Pokphand Group, one of the world's largest producers of animal feed and livestock.
The Charoen Pokphand Group has lucrative stakes in Chinese insurer Ping An, Hong Kong conglomerate CITIC, and telecom company True Corp. It also controls UK supermarket Tesco's operations in Thailand and Malaysia. Chearavanont is one of 26 Thais to feature on Forbes' global billionaires list.
Charlene de Carvalho-Heineken is the wealthiest person in the Netherlands by far and one of the richest women in the world.
The heiress's staggering wealth is derived from her 23% stake in Heineken. The Amsterdam-based multinational brewing company was launched by her great-grandfather, Gerard Adriaan Heineken, in 1864. Her husband Michel de Carvalho, sons Charles and Alexander de Carvalho and daughter Louisa Brassey all occupy seats on Heineken boards.
Forbes opted to leave Saudi Arabia's mega-rich off its 2018 list of global billionaires following a corruption crackdown in the kingdom and continues to omit the country's elite due to a lack of clarity over net worth figures.
However, Bloomberg has provided estimates. It ranks Prince Alwaleed Bin Talal Al Saud, who has interests in everything from real estate to oil, as the nation's number one thanks to his rumoured $14.8 billion (£11.8bn) fortune.
Once called the "Zuckerberg of Russia", Pavel Durov is the founder and owner of messaging app Telegram.

Li Xiting is the wealthiest man in Singapore with a $15.6 billion (£12.5bn) fortune.

The UK boasts some world-famous billionaires, including Sir Richard Branson and Sir James Dyson.
However, the richest citizen is Michael Platt, cofounder and CEO of BlueCrest Capital Management, one of the world's largest hedge fund firms. Platt recently edged out Sir James Ratcliffe to take the top spot among the UK's 55 billionaires and has largely flown under the radar. He maintains a low profile with one newspaper report claiming that many of his employees don't even know who he is.
Eyal Ofer is the most monyed person in Israel. The son of shipping magnate Sammy Ofer, who was the country's richest person until his death in 2011, Ofer inherited part of his father's business empire that very same year.
He has since expanded into other money-making areas, including real estate. He counts New York's 15 Central Park West, 1250 Broadway, and 50 United Nations Plaza among the prestigious properties he owns.
With over 50 billionaires – more than any other Latin American country – Brazil is awash with ultra-rich residents. Eduardo Saverin is the richest, with a net worth of $24.5 billion (£19.6bn).
Saverin cofounded Meta Platforms, formerly Facebook, with his Harvard classmate Mark Zuckerberg in 2004. He's now a venture capitalist, but the bulk of his wealth comes from his small but extremely lucrative stake in Meta.

Mining magnate Gina Rinehart is the richest person in Australia with a fortune of $30.1 billion (£24bn). Rinehart has transformed her late father's floundering iron ore company, Hancock Prospecting, into a flourishing business, raking in billions in the process.
In recent years she's made big investments in the rare earth minerals sector. Rinehart is also Australia's leading landowner and one of its premier cattle producers.
Swiss shipping magnate Rafaela Aponte and her Italian businessman husband Gianluigi (pictured) each have a net worth of $34 billion (£27.2bn).
This makes them the richest of Switzerland's many billionaires by some distance. The couple entered the shipping industry in 1970 when they purchased their first ship with a loan of $200,000. Today, they each own a 50% stake in MSC, the world's largest shipping line.
The richest person in Japan is Tadashi Yanai, the founder of Fast Retailing, the parent company of global fast-fashion chain Uniqlo.
