Areas of Hong Kong in the context of "Kowloon"

Hong Kong Island (simplified Chinese: 香港岛; traditional Chinese: 香港島; pinyin: xiāng gǎng dǎo; Jyutping: Hoeng1 gong2 dou2; Cantonese Yale: Hēunggóng dóu) is an island in the southern part of Hong Kong. The island, known originally and on road signs simply as "Hong Kong", had a population of 1,289,500 and a population density of 16,390 per square kilometre (42,400/sq mi), as of 2023. It is the second largest island in Hong Kong, with the largest being Lantau Island. Hong Kong Island forms one of the three areas of Hong Kong, with the other two being Kowloon and the New Territories.

In 1842, following the Qing dynasty's defeat at the First Opium War (1839–1842), Hong Kong Island was formally ceded in perpetuity to the United Kingdom under the Treaty of Nanking. The City of Victoria was then established on the island by British forces, named in honour of Queen Victoria. At that time, the island had a population of about 3,000 inhabitants scattered in a dozen fishing villages.

The New Territories is the largest of the three areas of Hong Kong, alongside Hong Kong Island and Kowloon. It makes up 86.2% of Hong Kong's territory, and contains around half of the population of Hong Kong. Historically, it is the region described in the Convention for the Extension of Hong Kong Territory. According to that treaty, the territories comprise the mainland area north of Boundary Street on the Kowloon Peninsula and south of the Sham Chun River (which is the border between Hong Kong and mainland China), as well as over 200 outlying islands, including Lantau Island, Lamma Island, Cheung Chau, and Peng Chau in the territory of Hong Kong.

Later, after New Kowloon was defined from the area between the Boundary Street and the Kowloon Ranges spanned from Lai Chi Kok to Lei Yue Mun, and the extension of the urban areas of Kowloon, New Kowloon was gradually urbanised and absorbed into Kowloon.

New Kowloon is an area in Hong Kong, bounded to the south by Boundary Street, and to the north by the ranges of the Eagle's Nest, Beacon Hill, Lion Rock, Tate's Cairn and Kowloon Peak. It covers the present-day Kwun Tong District and Wong Tai Sin District, and northern parts of the Sham Shui Po District and Kowloon City District.

The name of this area is rarely used in day-to-day life. Areas that belong to New Kowloon are usually referred to as a part of Kowloon. However, in land leases, it is common to refer to land lots in lot numbers as "New Kowloon Inland Lot number #".
