This graphic shows the biggest North American cities by population, based on data from the United Nations World Urbanization Prospects 2025.
Urban populations can be measured in different ways. In this methodology, the UN looks at satellite-mapped urban footprints for consistency. For this reason some city populations may not line up exactly as you may expect.

With the largest population by far, the Mexico City region drives almost 25% of Mexico’s GDP.
Trade and transportation is the capital’s most prominent sector, bolstered by shifting supply chains and nearshoring. After Mexico City, Guadalajara, known as the “Silicon Valley of Mexico” is the country’s second-most populous city, at 4.1 million.
Meanwhile, New York City sits at a population of 13.9 million in 2025. Since 2020, the financial hub has lost about 128,000 residents, with many moving to Florida, Texas, and California. In contrast, Los Angeles has grown by nearly 250,000 over the same period to reach 12.7 million.
Ranking fourth is Toronto, Canada’s leading financial center. Like Los Angeles, it has added roughly 250,000 residents since 2020, making it one of the country’s fastest-growing major cities. Looking ahead, Toronto is projected to grow by another 370,000 people over the next decade, largely driven by international migration.
