As well as the delta itself, the term Greater Bay Area refers to the dense network of cities that covers nine prefectures of the province of Guangdong, namely Guangzhou, Shenzhen, Zhuhai, Dongguan, Zhongshan, Foshan, Huizhou, Jiangmen and Zhaoqing, and the SARs of Hong Kong and Macau. The 2010/2011 State of the World Cities report, published by the United Nations Human Settlements Programme, estimates the population of the delta region at 120 million people; it is rapidly urbanising.

The eastern side of the GBA (Shenzhen, Dongguan) is the most developed economically and polluted. The western areas (Foshan, Zhuhai, Zhongshan, Jiangmen) are open for development. New transport links between Hong Kong, Macau and Zhuhai in the GBA are expected to open up new areas for development, further integrate the cities, and facilitate trade within the region. The new 50-kilometre Hong Kong-Zhuhai-Macau Bridge is the longest in the world.

The Greater Bay Area has become the world's workshop and is a major manufacturing base for products such as electronic products (such as watches and clocks), toys, garments and textiles, plastic products, and a range of other goods. Much of this output is invested by foreign entities and is geared for the export market. The Greater Bay Area accounts for approximately one third of China's trade value.

Private-owned enterprises have developed quickly in the Greater Bay Area and are playing an ever-growing role in the region's economy, particularly after year 2000 when the development environment for private-owned enterprises was greatly relaxed.

 Greater Bay Area (GBA)

The Greater Bay  Area (GBA) in Guangdong province, People's Republic of China is the low-lying area surrounding the Pearl River estuary where the Pearl River flows into the South China Sea.

It is one of the most densely urbanised regions in the world and one of the main hubs of China's economic growth.

This region is often considered an emerging megacity. The GBA is not a megalopolis but rather one rapidly forming megacity, and itself the southern end of a larger megalopolis running along the southern coast of China.

The river delta, is formed by three major rivers, the Xi Jiang (West River), Bei Jiang (North River), and Dong Jiang (East River). The flat lands of the delta are criss-crossed by a network of tributaries and distributaries of the Pearl River.

The Pearl River Delta is actually two alluvial deltas, separated by the core branch of the Pearl River. The Bei Jiang and Xi Jiang converge to flow into the South China Sea and Pearl River in the west, while the Dong Jiang only flows into the Pearl River proper in the east.

The Xi Jiang begins exhibiting delta-like characteristics as far west as Zhaoqing.. After passing through the Lingyang Gorge and converging with the Bei Jiang, the Xi Jiang opens up and flows as far east as Nasha Qu and as far west as Xinhui.

The Bei Jiang enters the delta plains at Qingyuan but doesn't begin to split until near Sanshui. From here the two main distributaries are Tanzhou Shuidao and Shunde Shuidao which form multiple mouths along the west side of the Pearl River's estuary. Two other distributaries, Lubao Yong and Xinan Yong, split from the Bei further north and converge with the Liuxi He to form the main branch of the Pearl River just north of Guangzhou. The other major city in the north section of the delta is Foshan.

The Dong Jiang flows through Huizhou into the delta. It begins diverging northeast of Dongguan into many distributaries, including the Dongguan Shuidao. Distributuares enter the Pearl River as far north as Luogang and as far south as Hu Men (Tiger Gate).
