What is the population of Singapore?

About 5.64 billion people. As of 2022, Singapore's total population is approximately 5.64 million, with 4.07 million citizens and permanent residents. The main ethnic groups are Chinese, Malay, and Indian, with the Chinese having the largest population. The main reasons for Singapore's population decline are the low fertility rate of the native population and the low willingness of Singaporeans to have children. Secondly, the quantity and quality of immigrants are difficult to control, and resources are scarce and space is limited.
