Christmas Island had a population of 1,843 residents as of 2016, the majority of whom live in settlements on the northern tip of the island. The main settlement is Flying Fish Cove. Around two-thirds of the island's population is estimated to have Malaysian Chinese origin (though just 21.2% of the population declared a Chinese ancestry in 2016), with significant numbers of Malays and white Australians as well as smaller numbers of Malaysian Indians and Eurasians. Several languages are in use, including English, Malay, and various Chinese dialects.
