The Most Populous Cities Around the World

Towering skyscrapers, concrete jungles, and endless traffic; these are the features we think of when picturing the world’s most populous cities. Over 50% of the world’s population live in megacities, a metropolitan area with more than 10 million inhabitants. Even more people travel to visit these megacities and sample everything they have to offer. Come with us to some of the most populous cities around the world and discover the hidden worlds within these bustling metropolises.

Coming in at the most populated city in the world, Tokyo feels like a well-oiled machine. Once a small Japanese fishing village called Edo, Tokyo’s population exploded in the 18th century after becoming Japan's official capital. Unlike most major cities, Tokyo’s population is actually decreasing, a trend that is thought to be caused by drops in birth rates as well as a major decline in immigration.

Despite the city’s large size, Tokyo maintains a high level of order. Its streets are immaculately clean and subways run smoothly, even during rush hour. Some of the most popular tourist attractions include the Senso-ji Temple, Shibuya Crossing, and Tsukiji Fish Market. For a unique cultural experience, be sure to attend a traditional tea ceremony or Sumo wrestling match. A visit in spring or fall is particularly beautiful due to the cherry blossoms and vibrant maple leaves.

Shanghai, China (26.3 million pop.)

China is no stranger to cities with immense populations — in fact, 10 of the world's 32 megacities are located here. Home to over a whopping 26 million people, Shanghai is China’s most populous city by metropolitan area.

Located on China’s central eastern coastline, Shanghai enjoys a subtropical climate year-round. The undulating Yangtze river flows lazily through the city and provides a unique addition to the stunning skyline. This area, known as The Bund, is a famous and historical promenade west of the city’s financial district. For even better views, take a cruise on the river by night. Shanghai is also the birthplace of xiaolongbao, or soup dumplings, which were first invented on the outskirts of the city in 1875. A visit to “The Paris of the East” isn’t complete without trying these delectable mouthfuls.

New Delhi, India (29.4 million pop.)

India is a feast for the senses, and as the country's capital city, New Delhi is a concentrated version of the nation in chaotic splendor. While oftentimes overwhelming for the first-time visitor, the city has evolved in the last few years to become not only a bustling megalopolis but a burgeoning creative hub as well.

No visit to New Delhi is complete without witnessing the India Gate, a 138-foot-tall WWI memorial in the center of the city. If you’re in search of the most popular tourist attraction in India, the Taj Mahal is only 2 hours outside the city by train. For a taste of the local Delhiite cuisine try paranthas, flatbread that is sometimes filled with cheese or vegetables, or chole bhature, a spicy chickpea curry with leavened bread.

São Paulo, Brazil (21.8 million pop.)

As the most populous city in the Americas, São Paulo had humble beginnings. Originally a small settlement founded by the Tupi people, it was discovered by Portuguese explorers in 1554 but regained its independence in 1822. For a respite from “Sampa’s” bustling urban sprawl, head to Parque do Ibirapuera for 390 acres of green space. Stroll the famous Avenida Paulista on Sundays when it is closed to through traffic and admire the towering skyscrapers the city is known for. For a truly unforgettable experience, snag tickets to a futbol match to get a true sense for this electric city and her inhabitants.

No visit to Brazil, and Sao Paulo in particular, is complete without trying feijoada, a hearty meat stew, and pão de queijo, cheesy bread rolls made with tapioca flour. Interestingly, São Paulo is home to the largest Japanese diaspora in the world. This has brought about a unique blend of Brazilian and Japanese cuisine in the form of temaki. You can find these hand rolled sushi cones at a temakeria in Sao Paulo’s Liberdade neighborhood.

Mexico City, Mexico (21.6 million pop.)

Sitting at 7,349 feet in elevation, Mexico City is a breathtaking capital. Once known as Tenochtitlan by the Mexica people, the city was originally built on an island surrounded by the enormous Lake Texcoco. The city has evolved from its former Aztec glory to become a tourist hotspot and popular weekend trip destination that is an enchanting mixture of ancient tradition and modernity.

Head to the center of town to see one of the largest Zocalos, or plazas, in the world. Stand in line to be blessed by an Aztec shaman and grab a delicious esquite, Mexican street corn in a cup, from a vendor. For a taste of Aztec cuisine itself head to a pulqueria where they serve pulque, a milky alcoholic beverage that is made from fermented maguey and comes in dozens of delicious flavors.

You can still see remnants of Lake Texcoco in the Xochimilco neighborhoods canals. Hop aboard one of the colorful floats for a cruise to the floating gardens or chinampas. Bring beer and snacks and drift the day away while being serenaded by local mariachi bands.
