Short Answer
The United States is home to some of the largest municipal populations in the world, but ‘largest city’ depends heavily on whether you count city proper, urban area, or metropolitan region. By the most common official measure—resident population within incorporated city limits—New York has held the top spot for generations. According to U.S. Census Bureau Vintage 2025 estimates released May 14, 2026, New York City’s population was 8,584,629, followed by Los Angeles at 3,869,089 and Chicago at 2,731,585. More recent 2026 projections from World Population Review show a similar order, with New York at 8,546,038, Los Angeles at 3,863,148, and Chicago at 2,727,758. The differences reflect estimation timing and methodology, but the overall picture is clear: the largest U.S. cities are concentrated in a handful of states, and the fastest growth is in Texas and the Sun Belt.

Explanation
When people ask about the largest U.S. cities, they are usually referring to the city proper—the population living within the legal boundaries of a municipal corporation. The U.S. Census Bureau defines an incorporated place as a city, town, village, or borough with legally established limits. This measure excludes suburbs and unincorporated areas that may be part of the same urban region, which is why a city like Miami ranks much lower than its metropolitan area would suggest.
The rankings change depending on the geography used. A metropolitan statistical area includes a core city plus surrounding counties with strong commuting ties, while an urban area is a densely developed region that may cross city and even state lines. For example, the New York metropolitan area has roughly 19 million people, but the city proper has about 8.5 million. This article focuses on city-proper populations, the most common basis for official city rankings.
Population estimates are updated annually by the Census Bureau using the latest decennial census as a baseline. The Vintage 2025 estimates, released in May 2026, incorporate births, deaths, domestic migration, and international migration. Because these are estimates rather than full counts, small year-to-year changes should be interpreted with caution, but the broad ranking order has been stable for decades.
Ranking Table
The table below shows the 12 largest U.S. cities by population using 2026 estimates from World Population Review, which are based on recent Census data and annual change rates. The official 2025 Census estimates for the top three are slightly higher, but the ranking order is identical.
| Rank | City | State | 2026 Population | Annual Change |
|---|---|---|---|---|
| 1 | New York | New York | 8,546,038 | -0.40% |
| 2 | Los Angeles | California | 3,863,148 | -0.14% |
| 3 | Chicago | Illinois | 2,727,758 | -0.08% |
| 4 | Houston | Texas | 2,419,191 | +0.86% |
| 5 | Phoenix | Arizona | 1,677,947 | +0.67% |
| 6 | San Antonio | Texas | 1,572,360 | +1.50% |
| 7 | Philadelphia | Pennsylvania | 1,567,280 | -0.35% |
| 8 | San Diego | California | 1,410,522 | +0.33% |
| 9 | Dallas | Texas | 1,336,440 | +0.42% |
| 10 | Fort Worth | Texas | 1,049,355 | +2.15% |
| 11 | Jacksonville | Florida | 1,032,061 | +1.36% |
| 12 | Austin | Texas | 1,011,743 | +0.84% |
Only these 12 cities have populations above one million. The next tier includes San Jose, Charlotte, Columbus, Indianapolis, San Francisco, Seattle, Denver, Oklahoma City, Nashville, and Washington, D.C., all between roughly 700,000 and 1 million residents.
Year-over-Year Change
Growth rates among the largest cities reveal a clear Sun Belt advantage. Among the top 12, Fort Worth, Texas grew fastest at +2.15% annually, followed by San Antonio at +1.50% and Jacksonville, Florida at +1.36%. Other fast-growing large cities include Charlotte (+1.94%), Seattle (+1.14%), and Oklahoma City (+1.06%).
By contrast, several older industrial and coastal cities are losing population. San Francisco declined by -1.23% annually, the steepest drop among major cities. San Jose fell -0.42%, New York -0.40%, Philadelphia -0.35%, Los Angeles -0.14%, and Chicago -0.08%. These declines are generally modest but reflect high housing costs, domestic out-migration, and post-pandemic shifts in where people choose to live.
Historical Data
Comparing 2026 estimates with the 2020 Census shows how the largest cities have changed over six years. The table below highlights the top five cities.
| City | 2020 Census Population | 2026 Estimate | Change | Percent Change |
|---|---|---|---|---|
| New York | 8,751,188 | 8,546,038 | -205,150 | -2.3% |
| Los Angeles | 3,896,473 | 3,863,148 | -33,325 | -0.9% |
| Chicago | 2,741,640 | 2,727,758 | -13,882 | -0.5% |
| Houston | 2,298,295 | 2,419,191 | +120,896 | +5.3% |
| Phoenix | 1,612,458 | 1,677,947 | +65,489 | +4.1% |
Houston and Phoenix have added the most residents among the top five, while New York, Los Angeles, and Chicago have all lost population since 2020. This pattern underscores the broader shift toward the South and West.
State Comparison
Texas stands out as the dominant state in the city population rankings. Five of the 12 largest U.S. cities are in Texas: Houston (4th), San Antonio (6th), Dallas (9th), Fort Worth (10th), and Austin (12th). California has three cities in the top 12—Los Angeles, San Diego, and San Jose—while New York has two if the town of Hempstead is included, though New York City alone is the largest.
Other states with one top-12 city each include Illinois (Chicago), Arizona (Phoenix), Pennsylvania (Philadelphia), and Florida (Jacksonville). The concentration of large cities in Texas reflects the state’s strong job growth, relatively lower housing costs, and business-friendly environment, which have attracted both domestic and international migrants for decades.
Methodology
The U.S. Census Bureau produces annual population estimates for all incorporated places using a cohort-component method. The process starts with the most recent decennial census count, then adds births, subtracts deaths, and estimates net domestic and international migration. Housing unit estimates and group quarters data are also used to refine the numbers. The Vintage 2025 estimates, released on May 14, 2026, cover the period through July 1, 2025.
For city rankings, the Census Bureau reports population for incorporated places, which include cities, towns, villages, and boroughs. A few census-designated places (CDPs) are also included in some listings, but the primary ranking focuses on municipal corporations. Consolidated city-counties, such as Jacksonville, Florida, and Indianapolis, Indiana, are counted as single entities, which can inflate their city-proper populations relative to cities with smaller boundaries.
Definitions
City proper refers to the population within the legal boundaries of a municipality. It is the most common measure for ranking cities but can be misleading because municipal boundaries vary widely. For example, Jacksonville covers 747 square miles, while San Francisco covers only about 47 square miles.
Metropolitan statistical area (MSA) is a larger region that includes a core city and surrounding counties with strong economic ties. The New York MSA, for instance, includes parts of New Jersey, Connecticut, and Pennsylvania and has a population of about 19 million, more than double the city proper.
Urban area is a densely developed region defined by the Census Bureau based on population density and land use. Urban areas can cross city and state lines and are useful for comparing the physical extent of cities, but they are not the same as municipal populations.
Why It Matters
City population rankings are more than trivia. They influence the allocation of federal and state funding for transportation, housing, education, and public safety. Larger cities often receive more formula-based grants, and population counts affect political representation at the local, state, and federal levels. Businesses also use population data to decide where to locate stores, offices, and distribution centers.
For residents and policymakers, understanding whether a city is growing or shrinking helps guide infrastructure investment, zoning decisions, and long-term planning. A city losing population may face declining tax revenue and underused schools, while a fast-growing city must manage housing shortages, traffic congestion, and pressure on public services.
Factors Behind the Trend
The current population shifts among large U.S. cities reflect several long-term forces. Housing affordability is a major driver: cities like San Francisco, Los Angeles, and New York have high housing costs that push residents toward more affordable metros in Texas, Arizona, and Florida. Job growth in technology, energy, and logistics has made Sun Belt cities attractive to workers, while remote work has allowed some people to leave expensive coastal areas without changing jobs.
Domestic migration has been a key factor. Texas and Florida have consistently gained residents from other states, while California, New York, and Illinois have lost more domestic migrants than they gained. International migration still adds population to gateway cities like New York and Los Angeles, but not enough to offset domestic losses in recent years. Climate and quality of life also play a role, with warmer weather and lower taxes drawing people to the South and West.
Limitations of the Data
City-proper population rankings have several limitations. First, municipal boundaries are not standardized, so a city with a large land area can rank higher than a denser city with a smaller footprint. Jacksonville, for example, includes most of Duval County, while Boston’s city proper is only 48 square miles. Second, the estimates are not full counts; they are projections based on administrative records and survey data, so they carry margins of error that are larger for smaller places.
Third, the rankings exclude unincorporated areas and many census-designated places, which can understate the true size of some urban communities. Finally, annual estimates can be revised when new data become available, so small differences between sources—such as the 2025 official estimate and the 2026 projection—should not be overinterpreted. The broad ranking order, however, has remained stable for decades.
