1. London - United Kingdom
London is the capital and largest city of both England and the United Kingdom (UK). It was established by the Romans over 2000 years ago under the name Londinium. The core area of the city, known as the City of London, has retained its medieval boundaries and remains a large-scale commercial hub. It wasn't until the 19th century that the name 'London' referred to a developed metropolis surrounding the central district. The city has grown into a global center for finance, commerce, education, and culture. London and New York are considered the two largest financial hubs in the world, with London's GDP being the largest in Europe. The headquarters of most of the top 100 UK companies and over 100 of the largest 500 companies in Europe are located in central London. The city's influence spans politics, finance, education, entertainment, fashion, and the arts, earning it the status of a global city and 'Caput Mundi'.
London is a major tourist destination, attracting visitors both locally and internationally. It has hosted the Summer Olympics in 1908, 1948, and 2012. The city is home to four UNESCO World Heritage Sites: the Tower of London, the Royal Botanic Gardens in Kew, the area including Westminster Palace, Westminster Abbey, and St. Margaret’s Church; and the historic settlement of Greenwich, which includes the Royal Observatory marking the Prime Meridian (0°) and Greenwich Mean Time (GMT). Other famous landmarks include Buckingham Palace, the London Eye, Piccadilly Circus, St. Paul's Cathedral, Tower Bridge, Trafalgar Square, The Shard, and the British Museum. London Underground is the oldest metro system in the world.
London is culturally diverse, with over 300 languages spoken. As of July 2016, the official population of Greater London stood at 8,787,892, making it the most populous city in the European Union. The Greater London Urban Area (the second-largest urban area in Europe) has a population of 9,787,426, while the entire metropolitan area of London is the largest in Europe, with a population of 14,040,163. Less than 70% of London's population is White, reflecting its high level of internationalism. The city's transport network, managed by Transport for London, is the oldest metro system in the world. London Heathrow is the busiest international airport globally by passenger traffic, with air traffic far exceeding any other city center in the world. The UK capital ranks fourth this year, partly due to the strength of the British pound and inflation, while prices have also surged due to demand and supply chain disruptions.


2. Tokyo - Japan
Tokyo is the capital and one of the 47 prefectures of Japan, located on the eastern coast of the Honshu Island in the Kanto region. It is home to the Imperial Palace and the Japanese government's primary offices. Not just a single city, Tokyo is the center of the Greater Tokyo Area. The administrative center is located in Shinjuku, while Setagaya is the largest district. The Tokyo metropolitan area is the most populous in the world, with a population ranging from 35 to 39 million people (depending on the definition), and it also has the highest GDP globally, reaching 1.479 trillion USD in 2008 (adjusted for purchasing power parity).
Tokyo ranks first in the Global Economic Power Index and third in the Global City Index. In 2014, TripAdvisor’s Global City Survey ranked Tokyo as the best overall city for experience, leading categories like “local friendliness,” “nightlife,” “shopping,” “local public transport,” and “street cleanliness.” In 2015, Tokyo was ranked as the 11th most expensive city for expatriates by Mercer, and the same ranking was held by the Economist Intelligence Unit's cost of living survey. In the same year, Tokyo was named the most livable city globally by Monocle magazine. The city topped the Safe Cities Index in 2017 and was ranked the third-best city for university students globally by QS in 2016 and second in 2018. Tokyo has hosted significant events such as the 1958 Asian Games, 1964 Summer Olympics, 1979, 1986, and 1993 G7 Summits, the 2019 Rugby World Cup, and the 2020 Summer Olympics and Paralympic Games. Despite the pandemic's impact, this densely populated metropolis remains highly ranked by ECA International. The city is renowned for its high housing, food, and living costs, even causing local reluctance to marry or have children.
Tokyo is considered a “command center” of the global economy by Saskia Sassen, along with London and New York. It is a global city, as ranked by GaWC in 2008. Tokyo, alongside New York and London, forms one of the three major global economic hubs. The Greater Tokyo Area, including Yokohama (38 million people), had a GDP of 2 trillion USD in 2012, making it the world’s largest urban economy. As of 2008, Tokyo was home to 47 companies listed in the Global 500, twice as many as Paris.


3. Tel Aviv - Israel
Tel Aviv-Yafo, often referred to simply as Tel Aviv, is the most populous city in the Gush Dan metropolitan area of Israel. Situated along the Mediterranean coast with a population of 460,613, it serves as the country’s economic and technological hub. If East Jerusalem is considered part of Israel, Tel Aviv ranks as the second largest city after Jerusalem; otherwise, it is the largest, ahead of West Jerusalem. Governed by the Tel Aviv-Yafo municipality, led by Mayor Ron Huldai, the city is home to numerous foreign embassies. It is categorized as a Beta global city and holds the 41st position in the Global Financial Centres Index. Tel Aviv has the third or fourth largest economy in Israel and the highest GDP per capita in the Middle East.
Today, Tel Aviv is known for having the highest cost of living in the world. The city attracts over 2.5 million international visitors every year. Often called the “party capital” of the Middle East, it boasts a vibrant nightlife and a 24-hour culture. Tel Aviv is also recognized as the world’s vegan food capital, with the highest per capita vegan population globally and numerous vegan restaurants scattered throughout the city. The city is home to Tel Aviv University, the largest university in Israel, with over 30,000 students.
Much of Tel Aviv’s growth can be attributed to the influx of Jewish refugees, which allowed the city to surpass Jaffa, which had a majority Arab population at the time. In 1950, Tel Aviv and Jaffa were merged into a single municipality, two years after Israel’s declaration of independence was made in Tel Aviv. The White City of Tel Aviv, a UNESCO World Heritage site since 2003, features the largest concentration of Bauhaus and other modernist-style buildings in the world. Israel’s coastal city continues to rank among the top 10 most expensive cities globally, partly due to the strength of its currency against the US dollar. Tel Aviv is also regarded as the new tech innovation center of the Middle East, attracting investments and a growing population.


4. Zurich - Switzerland
Zurich is Switzerland's largest city, with a population of 366,145 in 2004 and an urban area population of about 1.3 million. It serves as the capital of the canton of Zurich and is the nation's primary financial and cultural center. Though Bern is the political capital, Zurich is recognized as one of the most global cities in the world. A survey in 2006 ranked it as the city with the highest quality of life globally. The city's name likely derives from the Celtic term 'Turus,' with evidence found on an inscription from the 2nd century when the area was under Roman occupation; the city’s Roman name was Turicum.
As the largest city and financial hub of Switzerland, Zurich sits at the northern end of Lake Zurich, 409 meters above sea level, in the heart of the Swiss Plateau. The city features the busiest airport and largest railway station in the country, which creates a lasting impression on visitors. Zurich is renowned for its enviable quality of life, something many other nations aspire to. It is famous for its picturesque European-style streets, surrounded by rolling hills, serene lakes, and the distant Alps. When winter arrives, Zurich transforms into a magical wonderland. The city is home to more than 1,200 charmingly designed fountains, making it the city with the most fountains in Europe. The large lake offers a romantic setting for walking, cycling along the shore, or taking a boat ride, with public transportation being the most popular mode of travel.
Additionally, Zurich is often rated as one of the most desirable cities worldwide, known for its world-class museums and unique cultural festivals. During the 19th and 20th centuries, it became a favored destination for renowned writers, artists, and composers. The neighboring city of Geneva also consistently ranks highly, partially due to its use of the Swiss Franc. Zurich frequently appears on lists of the world's most expensive cities due to the high costs of housing, food, and entertainment.


5. Shanghai - China
Shanghai is China's largest city by population and the largest city in the world excluding suburbs. Located on China's eastern coast, it is one of the country's four direct-controlled municipalities. With an area of 6,340.5 km², Shanghai was ranked 25th globally by population in 2018, with 27 million residents, equivalent to the population of Cameroon. Economically, it ranks 11th in China, with a GDP of 3.82 trillion CNY (550 billion USD), comparable to Thailand. Shanghai also boasts one of the highest GDP per capita in China, second only to Beijing, at 137,000 CNY (approximately 20,130 USD). Shanghai is regarded as China's economic capital.
Today, Shanghai has the busiest port in the world, surpassing even Singapore and Rotterdam. Originally a small fishing village, Shanghai grew into one of the most important cities by the 20th century, becoming a major cultural, political, and intellectual hub during the Republic of China era. At one point, it was the third-largest financial center globally, trailing only New York and London, and was the largest trade center in the Far East in the late 19th and early 20th centuries. Following the rise of Mao Zedong and the Chinese Communist Party in 1949, Shanghai's economic growth slowed due to high taxation and anti-capitalist policies. However, following economic reforms and China's market liberalization in 1992 under Deng Xiaoping's leadership, Shanghai underwent rapid economic development, surpassing Shenzhen and Guangzhou to become the leading economic force in China.
Shanghai is often considered the financial and commercial hub of mainland China. Since 1992, the city has experienced exponential growth, outpacing southern Chinese cities like Guangzhou, Shenzhen, Zhuhai, and Xiamen. The Port of Shanghai ranks number one in the world for cargo throughput, handling about 443 million tons of goods annually. In terms of container traffic, Shanghai's ports rank third, behind Singapore and Hong Kong. Recently, Shanghai and Hong Kong have been competing for the title of China’s economic center. Shanghai’s GDP per capita is 12,784 USD, while Hong Kong's is 37,400 USD. The city has also become a global center for the headquarters of many multinational corporations in finance, commerce, banking, and education. Shanghai's GDP growth has consistently been in the double digits for 14 years. In 2005, its GDP growth rate was 11.1%, reaching 114 billion USD. By 2010, Shanghai’s GDP had reached 1.687 trillion CNY (256.3 billion USD), with GDP per capita at 76,000 CNY (11,540 USD). Shanghai continues to be recognized as China's economic capital.
In 2022, Shanghai saw further economic growth, particularly during the COVID-19 lockdowns, with prices skyrocketing in the city.


6. Guangzhou - China
Guangzhou is the capital and most populous city of Guangdong Province in southern China. It sits at the heart of the most densely populated urban region in mainland China. Administratively, it serves as the capital of the province. In 2015, the city's population in the administrative area was estimated at 1 million. Guangzhou is classified as a global city, and in recent years, has seen a significant influx of immigrants from Southeast Asia, the Middle East, Eastern Europe, and especially Africa. This has led to it being nicknamed "The Capital of the Third World." By 2008, 40% of Guangzhou's population had migrated from other Chinese provinces. Together with cities like Shanghai, Beijing, and Shenzhen, Guangzhou is one of China's most expensive real estate markets.
Guangzhou has a long history of over two centuries as a key player in foreign trade. It was the only port in China accessible to most foreign merchants, and during the First Opium War, it fell under British control. After losing its trade monopoly, Guangzhou continued to play a pivotal role as a major trading hub. In modern commerce, Guangzhou is known for the Canton Fair, China's oldest and largest trade show. Between 2013 and 2015, Forbes ranked Guangzhou as the best city for business in China. Guangzhou is the economic center of the Pearl River Delta and the heart of China's leading manufacturing economy. In 2006, the city's GDP exceeded 600 billion RMB (76.8 billion USD), with a per capita GDP of 85,000 RMB (11,000 USD), making it the top city in China for GDP. However, due to rapid industrialization, it is also considered one of the most polluted cities in China.
The China Export Commodities Fair, also known as the Canton Fair, is held annually in Guangzhou and has been a significant event for the city since 1957. The fair is the longest-running and largest trade show in China. From its 104th session onward, the fair has been held at the Guangzhou International Convention and Exhibition Center. As the capital of Guangdong and the largest city in the province, Guangzhou continues to see rising property prices due to its massive population and growing demand for housing.


7. Seoul - South Korea
Seoul, officially known as the Special City of Seoul, is both the capital and the largest metropolitan area of South Korea. Located on the banks of the Han River in the northwest part of the country, Seoul is classified as an Alpha global city and has a GDP of $43 billion, equivalent to Argentina's economy in 2019. It is one of the world's most expensive cities in terms of living costs, ranking third in Asia (after Tokyo and Singapore) and eighth globally on the 2020 Global Power City Index. Seoul is the central hub of the Seoul Capital Area, the most populous urban region in South Korea, and one of the largest cities in the world by population. Despite its small area of just 605.21 km²—smaller than London or New York—Seoul is one of the most densely populated cities worldwide.
Seoul is also known for its high level of digital connectivity, with more internet users than all the Sub-Saharan African nations combined (except for South Africa). Additionally, Seoul ranks as one of the 20 most important global cities. The capital region is home to approximately 26 million people (2020), making it the second-largest metropolitan area in the world after Tokyo. Seoul is the political, economic, and cultural heart of South Korea. The city has played a significant role in the country's history and was the birthplace of the 'Miracle on the Han River.' In 2020, Seoul registered over 24.3 million vehicles, contributing to the city's frequent traffic congestion. In recent years, the city government has implemented various measures to reduce pollution, with the successful restoration of Cheonggyecheon Stream—a once-polluted waterway now revitalized as part of major urban beautification projects—being a notable achievement.
As the headquarters for major global conglomerates such as Samsung, LG, Hyundai, Lotte, and CJ, Seoul's service sector has grown rapidly, making significant contributions to the national economy. South Korea derives 63.2% of its GDP from the service industry, surpassing the national average income. Major exports include electronics, automobiles, and machinery. This economic development has helped maintain a low unemployment rate of 3.4%. Seoul also attracts significant foreign direct investment, amounting to over $4 billion. However, South Korea's economy is facing challenges with slower growth, which could potentially impact the country's future development.
Seoul ranks 10th among the world's most expensive cities. The high costs of housing, rent, and living expenses put significant pressure on residents, particularly the younger population.


8. Hong Kong – China
Hong Kong is a Special Administrative Region located on the southeastern coast of China. It is one of the two Special Administrative Regions of the People's Republic of China, the other being Macau. This region consists of over 260 islands and lies east of the Pearl River Delta, bordered by Guangdong Province to the north and the South China Sea to the east, west, and south. The area includes Hong Kong Island, ceded to China in 1841, the Kowloon Peninsula, ceded in 1860, and the New Territories, which were leased to the UK for 99 years in 1898. All of these were returned to China in 1997. Hong Kong has grown to become one of the world's leading financial and manufacturing hubs.
Hong Kong’s economy is a highly developed capitalist system built on a market economy, low taxes, and minimal government interference. It is an important financial and trade center, housing the headquarters of many Asia-Pacific companies. With its high GDP per capita and total GDP, Hong Kong is the wealthiest urban center in China. As of 2016, Hong Kong’s GDP reached $316,070, ranking 34th globally and 11th in Asia. The currency of Hong Kong is the Hong Kong Dollar, which has been pegged to the US Dollar since 1983. The currency exchange rate fluctuates within a narrow band of 7.75 to 7.85 HKD per 1 USD. The Hong Kong Stock Exchange ranks as the sixth-largest in the world, with a market capitalization of approximately $1.71 trillion. In 2006, the value of initial public offerings conducted in Hong Kong was the second-largest globally, only behind the London Stock Exchange.
The Hong Kong economy is predominantly service-based, with services accounting for 92.7% of its GDP. In the past, manufacturing played a key role in the economy, especially after World War II when Hong Kong industrialized rapidly. During the 1970s, Hong Kong's economy grew at an average annual rate of 8.9%, driven by exports. However, in the 1980s, the economy swiftly transitioned into a service-based one, growing at 7.7% annually. Manufacturing activities largely moved to Mainland China, and today industry accounts for just 9% of the economy. As Hong Kong matured into a financial center, its growth slowed to 2.7% annually in the 1990s. Along with Singapore, South Korea, and Taiwan, Hong Kong is often referred to as one of the Four Asian Tigers due to its rapid growth and industrialization from the 1960s to the 1990s.
In the 2022 annual rankings, which are based on various factors such as basic food prices, housing costs, transportation, and currency exchange rates, Hong Kong ranked as the most expensive city in the world for the third consecutive year.
