List of counties in Delaware

Wikimedia list article

The state of Delaware has three counties: New Castle, Kent, and Sussex, the fewest counties of any U.S. state.[1] The origin of the county boundaries goes back to former court districts. The powers of the counties' legislative bodies are limited to issues such as zoning and development.

Politics and governmentEdit

Each county elects a legislative body (known in New Castle and Sussex counties as the County Council, and in Kent County as the Levy Court). The counties are able to raise taxes and borrow money. They also have control over garbage disposal, water supply, sewerage, zoning, development, and building codes.[2]

Most functions which are handled on a county-by-county basis in other states—such as court and law enforcement—have been centralized in Delaware, leading to a significant amount of power in the Delaware state government.
