Ohio Cities by Population 2026
About Ohio
Ohio’s local governance is defined by 88 counties and over 900 incorporated municipalities, which include cities and villages. Ohio’s counties and municipalities provide essential services, with counties often serving rural and unincorporated areas while municipalities focus on localized governance and services.
Columbus, Ohio‘s largest city, operates under a strong mayor-council government, where the mayor holds executive power and oversees city departments such as police, public health, and public works. The Columbus City Council serves as the legislative branch, passing ordinances, approving budgets, and shaping policy for the city’s diverse and growing population.
Cleveland and Cincinnati similarly follow a mayor-council structure, with executive authority concentrated in the mayor’s office and legislative functions handled by city councils. These cities manage comprehensive services such as public transportation, safety, utilities, and economic development independently of county jurisdiction.
Smaller municipalities often opt for a council-manager system, in which an elected council sets policies and hires a professional city manager to handle daily operations. Cities like Dayton and many smaller villages have adopted this structure, promoting professionalized management while retaining democratic oversight through elected councils.
Counties like Franklin County, Cuyahoga County, and Hamilton County administer services in unincorporated areas, managing public health, emergency services, and infrastructure. Boards of county commissioners oversee these functions, ensuring effective service delivery across rural and suburban regions.
Unincorporated communities, prevalent in Ohio’s rural counties, depend on county government for services such as law enforcement, zoning, and infrastructure. Townships, which function as a form of local government in unincorporated areas, often manage parks, roads, and other localized issues, with elected trustees serving as leaders.
Regional planning agencies and councils of government foster cooperation between Ohio’s counties and municipalities, addressing cross-jurisdictional concerns like transportation, water resources, and economic development to ensure balanced growth across the state.
