National Registration Identity Card in the context of "Demographics of Singapore"

As of June 2025, the population of Singapore stood at 6.11 million. Of these 6.11 million, 4.20 million are residents, consisting of about 3.66 million citizens and 540,000 permanent residents (PRs). The remaining 1.91 million people living in Singapore are classed as non-residents, defined as "foreign workforce acrossall pass types, dependants and international students".

Singapore is a multi-racial, multi-ethnic and multi-cultural society. Major religions include Buddhism, Christianity, Islam, Taoism and Hinduism. Its population is broadly classified under the CMIO system: Chinese, Malay, Indian and Other. While Malays are recognised as the indigenous community, 75.5 percent of citizens and permanent residents are ethnic Chinese, with Malays and Indians making up 15.1 and 7.6 percent respectively. These three groups make up 98.2 percent of the ethnic citizen population, while the remaining 1.8 percent, categorised as Other, are largely Eurasians. Non-residents, who make up 29 percent of the overall population, are excluded from resident statistics. Officially, mixed-race Singaporeans are typically assigned their father's race, though their identity card may also reflect both parents' ethnicities.
