A borough is a specific type of administrative division found in various countries, particularly in the United States and the United Kingdom. In the U.S., boroughs can refer to a town or a district within a city, often with its own local government. For example, Brooklyn is a borough of New York City.
In the UK, a borough is typically a town or urban area that has been granted certain administrative powers. Boroughs can be classified as either metropolitan or non-metropolitan, depending on their location and population density. Each borough has its own council, responsible for local governance and services.
