Hong Kong consists of a peninsula and 263 islands. The Islands District consists of some twenty large and small islands which lie to the south and southwest of Hong Kong. Notable areas that are part of the Islands District include Chek Lap Kok, the reclaimed island on which Hong Kong International Airport is located, Tung Chung on northern Lantau near the airport, and Discovery Bay, a large private residential area on eastern Lantau.
With an area that is 16% of Hong Kong and a population that is 2% of Hong Kong, the Islands District is the largest in terms of area and also the least populated. It is therefore the district with by far the lowest population density of 783/km2 (2,030/sq mi). The outlying islands are notable for a more relaxed way of life than that of Hong Kong Island and Kowloon Peninsula. The district has the third-youngest residents.
As of 2021, the district has a population of 185,282. 78.1% of the population are Chinese. Ethnic minority groups include White (5.8%) and Filipino (5.3%).
