1. In the administrative divisions of the United States, counties and cities are parallel levels of governance, and there is no question of one being larger than the other.2. The U.S. system of local government is structured in a three-tiered hierarchy, with states being the first level, counties the second, and cities the third.3. At the sub-county level, there may also be smaller administrative divisions such as townships or districts.4. Counties are subdivisions of a state, and their boundaries and governmental structures are determined by the state's constitution and laws.5. Some areas may not have incorporated cities, only counties, while other regions may have both counties and cities.6. Consequently, counties and cities in the United States are parallel levels of administrative division, and there is no inherent size difference between them.
