What Is the Largest City in the United States?

New York City holds the title of the largest city in the United States, with a population somewhere around 8.4 to 8.8 million people depending on which recent estimate you use. That's more than double Los Angeles, the second-largest city, and roughly equal to the combined populations of Los Angeles, Chicago, and Houston put together — the country's second, third, and fourth most populous cities.

This isn't a recent development, either. Every single U.S. census since the very first one in 1790 has ranked New York as the country's most populous city. Back then, it had just over 33,000 residents. It has held the top spot through every wave of immigration, industrialization, and urban shift the country has gone through since.

Top 10 Largest U.S. Cities by Population

Only nine U.S. cities currently have more than a million residents within their official city limits — fewer than most people assume, mainly because sprawling metro areas often span dozens of separate incorporated cities rather than one continuous municipality.

New York City Quick Facts

• New York City's population is larger than the entire population of most U.S. states.
• The city has topped every U.S. census since the first one in 1790, when it had roughly 33,131 residents.
• California places more cities in the national top 100 than any other state, followed closely by Texas.
• New York City proper spans about 300 square miles across five boroughs — Manhattan, Brooklyn, Queens, the Bronx, and Staten Island.
• Several Sun Belt cities, including Phoenix, Houston, and Austin, are gaining population fast enough to reshape the rankings within a decade, even as New York and Los Angeles see modest declines.

Why "Largest City" Depends on What You're Measuring

City population rankings look deceptively simple until you dig into how "city" gets defined. The numbers above reflect population within official city limits — the legal boundary drawn by each municipality's government, not the broader urban region people typically picture. New York's metro area, spilling into New Jersey, Long Island, and parts of Connecticut and Pennsylvania, held nearly 19 million residents in recent estimates, and its metro region alone dwarfs the population of many entire countries.

Sun Belt cities complicate the picture further because many of them, especially in Texas and Arizona, have annexed surrounding suburban land over the decades, inflating their official city-limit populations relative to older Northeastern and Midwestern cities that are boxed in by long-established neighboring municipalities. Houston and Phoenix, for instance, rank as high as they do partly because their city boundaries stretch across enormous areas compared to a geographically compact city like Boston or Philadelphia.

New York's Staying Power

Population leadership rarely holds this steady for this long anywhere in the world, let alone in a country that has changed as dramatically as the U.S. has since 1790. Waves of immigration through Ellis Island in the late 19th and early 20th centuries cemented New York's role as the country's demographic gateway, a function the region still serves today as the leading metropolitan entry point for legal immigrants nationwide.

Geography helped too. A deep natural harbor made New York one of the most valuable ports on the Atlantic coast long before the country existed in its current form, and that early commercial advantage compounded over centuries into the financial, cultural, and media dominance the city holds now.

Did You Know?

Life expectancy for New Yorkers has historically outpaced the national average, a detail demographers often attribute to the city's dense public transit access, extensive parkland, and concentration of hospitals and medical research institutions.

San Jose, California briefly held a spot among the nation's ten largest cities in recent years, only to drop back below the million-resident threshold as growth patterns shifted — a reminder that even top-ten rankings aren't permanently fixed.

New York City's population alone exceeds that of dozens of individual U.S. states, meaning more people live within its five boroughs than in the entire states of Vermont, Wyoming, and Alaska combined several times over.

New York City Related Questions People Ask

Is New York City bigger than Los Angeles? By population, yes — more than double. Los Angeles covers more land area than New York, but New York's population density is dramatically higher.

What's the largest U.S. metro area, as opposed to city? The New York metropolitan area, which spans parts of New York, New Jersey, Connecticut, and Pennsylvania, remains the largest metro region in the country by a wide margin over second-place Los Angeles.

Which U.S. city is growing the fastest? Sun Belt cities like Austin, Phoenix, and Houston have posted some of the strongest recent growth rates, driven by job opportunities and comparatively lower costs of living, while cities like New York and Los Angeles have seen slight population declines in recent estimates.

How many U.S. cities have over a million people? Only nine, as of the most recent estimates — a number that has actually shrunk slightly in recent years as some cities dipped just below that threshold.

Why do some Texas cities rank higher than expected for their size? Annexation policy plays a big role. Texas cities have historically been able to expand their municipal boundaries more easily than cities in older, more built-out states, which inflates their official population figures relative to their urban core.

A Title That Hasn't Changed in Over Two Centuries

What's most remarkable about New York's position isn't just its current size, but how long it has held onto the top spot without interruption. Industrial booms, suburban flight, financial crises, a global pandemic — none of it has been enough to knock New York out of first place since the country started counting. Whether that streak survives the next few decades of Sun Belt growth remains an open question, but for now, no other American city is within striking distance.
