In urban planning, what does the term "CBD" stand for?

The term "CBD" stands for Central Business District. This refers to the commercial and business center of a city, often characterized by a high concentration of retail shops, offices, and cultural institutions. The Central Business District is typically the hub of economic activity in urban areas, playing a critical role in the overall economic landscape of a city. It usually features a dense concentration of skyscrapers, public transportation systems, and is often situated at the geographical heart of the city, making it an essential zone for both residential and commercial developments.

The other options either misinterpret or redefine the standard terminology used in urban planning. For example, the term "Central Building District" does not commonly exist within urban planning lexicon, and "Community Business District" suggests a more localized business focus that lacks the broader significance and investment characteristic of a CBD. "City Bureau of Development" implies a governmental body rather than an area of economic concentration. Thus, Central Business District is the most accurate and widely recognized term for this urban planning concept.
