Total Number of Mayors in the United States
The United States has thousands of incorporated municipalities, and each city or town with a mayor form of government has at least one mayor. The exact count changes as cities incorporate, merge, or change their charter structures. According to the U.S. Census Bureau's most recent municipal counts, there are roughly 19,500 to 20,000 incorporated places, and the vast majority operate under a mayor-council or council-manager system where a mayor serves as the chief elected or appointed leader. For detailed city and town counts, see the U.S. Census Bureau's data on incorporated places here.
Not every municipality uses a strong mayor system; many smaller towns use a council-manager structure where the mayor is a ceremonial chair of the city council. In these cases, the number of individuals holding the formal title of mayor still equals the number of incorporated municipalities that choose a mayor-led governance model. The National League of Cities tracks trends in municipal governance and provides updated reports on how cities structure their executive leadership here.
Types of Mayors and City Government Structures
Mayor-Council System
In the mayor-council system, the mayor acts as the chief executive of the city, with powers that can range from strong executive authority to a more limited role depending on the charter. Large cities like New York, Los Angeles, and Chicago use a strong mayor system where the mayor controls the city budget, appoints department heads, and enforces city laws. Smaller cities often use a weak mayor system where the mayor has limited administrative power compared to the city council.

Council-Manager System
In the council-manager system, the city council appoints a professional manager to run day-to-day operations, while the mayor typically serves as a presiding officer and representative of the city. This structure is common in mid-sized and smaller cities across the country. The International City/County Management Association provides data on how many municipalities use this form of government here.
Notable Mayoral Roles and Recent Trends
Mayors in Major U.S. Cities
The largest cities in the United States have high-profile mayors who often influence national policy on issues like housing, transportation, and public safety. As of the latest available data, the mayors of the top 10 most populous cities, including New York, Los Angeles, and Chicago, are elected every four years in most cases. Some cities, such as Washington, D.C., have a mayor with a unique status as the head of a federal district rather than a state municipality.
Recent trends show an increasing number of cities adopting strong mayor systems to streamline decision-making, while others are shifting toward council-manager models to emphasize professional administration. The number of cities with term limits for mayors has also grown, with many major municipalities capping mayoral service to two or three consecutive terms.
