, although the latter may result from consolidation of a city and a county and may also have the same powers as a consolidated city-county. An independent city is a city not deemed by its state to be located within the boundary of any county and considered a primary administrative division of its state. A consolidated city-county differs from an independent city in that the city and county both nominally exist, although they have a consolidated government, whereas in an independent city, the county does not even nominally exist. Furthermore, a consolidated city-county may still contain independent municipalities maintaining some governmental powers that did not merge with the rest of the county. Not considering

Overview

Consolidated city-counties are typically formed to address particular government challenges. Among the benefits of having a unified jurisdiction include potential cost savings, more efficiency, increased legal powers and revenue sources, and a more streamlined planning system. Most consolidated city-counties have a single chief executive that acts as both the city mayor and as the head of the county government, and a multi-district elected body that serves as both the city council and as the county legislative body. In many states, consolidated city-counties must be approved by voters. According to information compiled by former
