Singaporeans are an ethnic group comprising citizens who identify themselves as a nation with the sovereign island city-state of Singapore. Singapore is a multi-racial, multi-cultural, multi-religious, and multi-lingual country. Singaporeans of Chinese, Malay, Indian and Eurasian descent have made up the vast majority of the population since the 19th century. The Singaporean diaspora is also far-reaching worldwide. In 1819, the port of Singapore was established by Sir Stamford Raffles, who opened it to free trade and free immigration on the island's south coast. Many immigrants from the region settled in Singapore. By 1827, the population of the island was composed of people from various ethnic groups2. Singapore is a multilingual and multicultural society. It is home to people of many different ethnic, religious and national origins -- the majority of which are of Chinese, Malay, Indian and Eurasian descent. The Singaporean identity was fostered as a way for these different groups to integrate and identify as one with the nation, while preserving the culture and traditions of each group without assimilating minority cultures into a single majority culture. According to a 2017 survey by the Institute of Policy Studies, 49% of Singaporeans identify with both the Singaporean identity and their ethnic identity equally, while 35% would identify as "Singaporeans" first and 14.2% would identify with their ethnic identity. As of 2019, the population of Singaporeans stands at 4,026,200 and the population of Overseas Singaporeans stands at 340,751, with 217,200 individuals retaining their citizenship. The earliest records of settlement on the island date back to the 2nd century, where the island was identified as a trading port which was part of a chain of similar trading centres that linked Southeast Asia with the Tamil Indians and the Mediterranean. The earliest settlers of the island were known as the Orang Laut, and the island was an outpost of the Srivijaya Empire until it was invaded by the Tamil Emperor Rajendra Chola I of the Chola Empire in the 11th century.
