The 10 Largest Cities in California by Population
California’s cities aren’t just population hubs; they’re economic powerhouses, cultural melting pots, and innovation epicenters driving the world’s 5th-largest economy. From Los Angeles’ entertainment empire to Silicon Valley’s tech dominance, discover how these 10 largest cities shape global trends, attract millions, and define the Golden State’s unstoppable growth.
California is the most populous state in the United States, with an estimated population of nearly 40 million people as of 2024—more than the entire population of countries like Canada or Poland. Spanning over 163,000 square miles (approximately 423,970 square kilometres), it is also the third-largest state by area. Known for its vast and varied geography, California features deserts, mountains, forests, and a coastline stretching over 800 miles along the Pacific Ocean.
Its urban centres are hubs of economic activity, cultural expression, technological innovation, and political influence, contributing to what is recognised as the largest sub-national economy in the world. California’s gross state product (GSP) surpassed $4 trillion in 2023, placing it as the fifth-largest economy globally if it were a standalone nation.
The state’s urban landscape is marked by an impressive number of densely populated cities. According to the United States Census Bureau, two California cities, Los Angeles and San Diego, have populations exceeding 1 million, while at least 72 cities have between 100,000 and 1 million residents.
