As of June 2021, the population of Singapore stands at 5.45 million. Of these 5.45 million people, 4 million are residents, consisting of 3.5 million citizens and 500,000 permanent residents (PRs). The remaining 1.45 million people living in Singapore are classed as non-residents, a group consisting mainly of foreign students and individuals on work passes.
Singapore is a multiracial, multiethnic, and multicultural Asian society. Major religions include Buddhism, Christianity, Islam, Taoism, and Hinduism. Its people are broadly organised under the CMIO (Chinese–Malay–Indian–Other) system of categorisation. Although Malays are recognised as the indigenous community, 75.9% of the citizens and permanent resident visa holders are ethnic Chinese, with ethnic Malays and Indians comprising 15.0% and 7.5% respectively. Together, the three largest ethnic groups comprise 98.4% of the citizen population. The remaining 1.6% comprises members of "Other" races, which comprises largely Eurasians. Despite long term occupancy, Singapore excludes 27% of the population as non-residents for the purpose of resident statistics. Officially, mixed-race Singaporeans are often regarded as having the race of their father. However, race categorisation, for example on an individual's identity card, may also reflect both ethnicities of their parents.
There are four official languages in Singapore – English, Malay, Mandarin and Tamil. Malay is the symbolic national language, while English is the main working language. Education in Singapore is bilingual, with English being the medium of instruction. Students are also required to learn a second language, usually Malay, Mandarin, or Tamil. Singlish, a local creole and accent, is often used in colloquial speech between all native races of Singapore. There is also Singdarin, a Mandarin creole.
The annual total population growth rate for the year 2020 was -0.3%. Singapore's resident total fertility rate (TFR) was 1.10 in 2020; the Singaporean Chinese, Malay and Indian fertility rates were 0.94, 1.
