Oregon Cities by Population 2025

Oregon’s local governance consists of 36 counties and more than 240 incorporated cities. Counties provide services in rural and unincorporated areas, while cities manage local services, planning, and governance within their boundaries.

Portland, Oregon’s largest city, is unique with its commission form of government. City commissioners serve as heads of specific departments, making Portland one of the few major U.S. cities without a traditional mayor-council structure. This arrangement emphasizes collaborative decision-making and hands-on management of city services like public safety, transportation, and housing.

Eugene and Salem, Oregon’s other major cities, operate under council-manager governments. In these systems, the city council sets policies and a professional city manager oversees daily administration. This structure provides strong policy direction while maintaining a focus on efficient service delivery and local responsiveness.

Smaller cities and towns, such as Bend and Ashland, often use either council-manager or strong-mayor structures, depending on local needs and historical preferences. This flexibility allows communities to adapt governance to their unique challenges and opportunities.

Oregon’s counties, including Multnomah County and Deschutes County, handle services for unincorporated areas, focusing on public health, law enforcement, land use, and infrastructure. Boards of county commissioners manage these services, providing essential support to rural and less densely populated regions.

Unincorporated areas in Oregon often rely on county services, with many residents participating in local advisory committees to communicate community needs. This arrangement ensures representation and access to necessary services without formal incorporation.

Regional planning organizations and councils of governments promote cooperation between municipalities and counties, tackling challenges such as growth management, transportation, and environmental sustainability to balance development across the state.
