This Is The Largest City In North America By Population (And It's Not NYC)

Picturing a crowded city likely brings images of Manhattan's packed subways, busy intersections, and crowds lining up for Broadway shows and touristy restaurants. And those images are certainly not incorrect; New York City is the most populated city in the United States. However, it's not the most populous city in North America. That distinction belongs to its neighbor to the south.

As of 2026, Mexico City, Mexico, has a population of just over 9 million, according to World Population Review. That number surpasses the U.S. Census Bureau's estimated 8.5 million residing in NYC. When you zoom out further and look at the entire Mexico City metro area, that population more than doubles to 21 million people. By comparison, NYC's metro area counts roughly 20 million residents, still slightly behind Mexico City's metropolitan population.

However you look at it, both cities are huge. The capital city is among Mexico's top attractions for adventurous tourists, but Mexico City is more than just a vacation spot. The city is also considered the top destination in the world for business travelers, according to Forbes. Additionally, Mexico City is the political and economic hub of the country, with employment opportunities across a range of industries, which partially explains its large population.

While it's not without the problems many massive cities encounter, Mexico City has undergone an urban renewal over the past decade. This has combined a more laid-back lifestyle with cultural and economic opportunities for city residents. Another contributing factor to the city's growth can be linked to the COVID-19 pandemic. Since then, a wave of Americans have relocated to Mexico City, with many attracted to its relatively low cost of living.

Of course, as with all cities, a person's lifestyle will dictate expenses. But overall, the cost of food and transportation is lower than in other North American cities. The city is also navigable, even for those without a vehicle. In fact, Mexico City has the largest subway system of any Latin American city, according to Ibero Ciudad de México. Combined, its 12 lines stretch more than 140 miles, and an estimated 7 million people use the service every day.

Mexico City's urban renewal and strong infrastructure aren't an accident: The city has invested in its housing, cultural institutions, transportation, and a revitalization of its historic city center since the beginning of the 21st century. Of course, it's recommended to visit any city or country before making a big move. Since Mexico is considered one of the 10 most affordable countries to visit, a quick trip to explore it for yourself should certainly be on your calendar.

Just because Mexico City is the continent's most populous hub doesn't mean you have to relocate your entire life there, of course. The city remains a popular tourist destination for its cultural, historic, and gastronomic experiences. In fact, the travel company Tourlane placed Mexico City at the top of its "World's Best Cities for Art and Museums" list. The site specifically cited Mexico City's National Museum of Anthropology, which is Mexico's largest and most-visited museum. The museum has more than 1 million pieces spanning 16 galleries. Since it's located in the city center, it's easily accessible via transportation routes and nearby accommodations.

For those looking to expand their palate along with their cultural understanding of the country, Mexico City offers a wide range of culinary experiences. Nine Mexico City restaurants were named to La Liste's "Top 1,000 Restaurants Worldwide" in 2026. You'll also find numerous Michelin-approved restaurants.

Mexico City Benito Juárez International Airport (MEX) is the main airport that serves Mexico's capital city and offers connections throughout the continent. More than 20 airlines utilize the airport, and it offers multiple transportation routes into the city center, including taxis and a bus terminal. For those unsure where to begin, consider using the only map of Mexico you'll need for your upcoming trip.
