Final answer:
Virginia's cities are unique because they are not located in counties, making them independent municipal entities with their own governing systems.
Step-by-step explanation:
In contrast to other states, Virginia's cities are unique because they are not located in counties. This means that cities in Virginia are independent entities and are not administratively subordinate to any county. This is an exception to the common practice wherein most cities across the United States fall under the jurisdiction of the county in which they are geographically situated.
Virginia's form of municipal organization ensures that each city governs itself and handles its own municipal affairs without county oversight. This independent city status allows for the provision of services and governance directly by the city government, which in many cases, includes a city council and a city manager system.
Within Virginia, this approach to local governance is part of the state's broader commitment to a system where cities and counties are distinct and operate with separate governing bodies.
