Hong Kong (??, see Name section) is one of the two Special Administrative Regions of the People’s Republic of China, the other being Macau. It is situated on China’s south coast and, enclosed by the Pearl River Delta and South China Sea, it is known for its expansive skyline and deep natural harbour. With a land mass of 1,104 km2 (426 sq mi) and a population of seven million people, Hong Kong is one of the most densely populated areas in the world. Hong Kong’s population is 93.6% ethnic Chinese and 6.4% from other groups. Hong Kong’s Cantonese-speaking majority originate mainly from the neighbouring Canton (now Guangdong) province, from which many of them fled to escape wars and Communist rule in the 1930s to the 1960s.
