The Central Business District of Sydney, Australia.

A central business district (CBD) is the commercial and often geographic heart of a city. In Australia, Bosnia & Herzegovina, China (especially Hong Kong), Ireland, Kenya, New Zealand, Singapore and South Africa, the phrase is commonly used, and is often colloquially abbreviated to "CBD".

Definition

Overview

The term city centre (or city center) is similar to CBD in that both serve the same purpose for the city, and both are seen by a higher-than-usual urban density as well as the often having the tallest buildings in a city. City centre differs from downtown in that the latter can be geographically located anywhere in a city, while a city centre is generally located near the geographic heart of the city. London, United Kingdom, effectively has three city centres, the City of London, the medieval City of Westminster and Canary Wharf. Lucknow, India has three CBDs. The shape and type of a CBD or downtown almost always closely reflect the city's history. Cities with maximum building height restrictions often have a separate historic section quite apart from the financial and administrative district. In cities that grew up suddenly and more recently, such as those in the western half of North America, a single central area will often contain all the tallest buildings. It has been said that downtowns (as understood in North America) are therefore a separate phenomenon.^[2]

Central business districts usually have very small resident populations. For example, the population of the City of London declined from over 200,000 in 1700 to less than 10,000 today. In some instances, however (and particularly in large Australian cities), CBD populations are increasing as younger professional and business workers move into city centre apartments.

The alternative term city centre is used in Britain and Ireland, and also in some urban areas of British-influenced countries, such as the Commonwealth) and China (). It can also be translated as "city core". In the United Kingdom, Australia, South Africa, Canada and New Zealand, the term is often just shortened to "city", as in "going to the city". This term is also used in the New York City area in the same manner, using the term the city to mean Manhattan. One exception is in London where "the City" specifically refers to the City of London financial district rather than to any other part of central London. In the UK, Australia, Kenya, New Zealand, and Ireland, it is often also referred to as "town" ("going (in)to town", "going up town", or "going down town"). In Kenya "going (in)to town" usually means going to Nairobi, while going to the "city centre" means going to the financial core of Nairobi, which is now also referred to as the CBD.

Germany

In Germany the terms Innenstadt or Stadtmitte may be used to describe the central business district. Both terms can be literally translated to mean "inner-city" and "city-centre". While most German cities only have one central business district, Berlin has three. Due to Berlin's history of division during the Cold War, the city contains central business districts both in West Kurfürstendamm and East Berlin (Alexanderplatz), as well as a newly built business center near the Potsdamer Platz. The city's historic centre, location of the Reichstag building as well as the Brandenburg gate and most federal ministries was largely abandoned as the Berlin Wall cut through it. Only after the re-unification with the construction of numerous shopping centers, government ministries, embassies, office buildings and entertainment venues, was the area revived.

Lebanon

Although officially called Beirut Central District, the Lebanese use the French term Centre Ville to refer to the city center, which overlooks the Saint George Bay.?

Turkey

In Turkey, the term Çar?? is used to describe the central business district.

United States and Canada

Some cities in the United States and Canada, such as Vancouver, Minneapolis, and Dallas, Texas, have mixed use districts known as "uptown" in addition to the primary downtown core areas. In some cities, such as Charlotte, Chicago, and Oklahoma City, "uptown" is instead the historic name for a separate business center or neighborhood. Philadelphia and Wilmington, Delaware use the term center city instead of downtown for their central business districts. Some cities, such as Toronto, regard as many as four business districts as being central. Whereas in Los Angeles, the city core is simply known as downtown LA.

By broad definition, New York City's CBD comprises the whole southern half or third of Manhattan island. Narrow definitions include only a square mile or two (3-5 km²) of Midtown as central, with the lowest tenth of the island, including the Financial District, being a secondary business district rather than the central one. Similar narrow and broad definitions are applied to the Chicago's downtown high rise districts.
