A central business district (CBD) is the commercial and business center of a city. It typically features a high concentration of offices, retail shops, and cultural institutions. The CBD is often characterized by tall buildings and significant foot traffic, making it a hub for economic activity and employment. CBDs are usually well-connected to public transportation, facilitating easy access for workers and visitors. They play a crucial role in urban planning and development, influencing surrounding neighborhoods and contributing to the overall economy of the city. Examples of notable CBDs include Manhattan in New York City and The City of London.
