Overview
Singapore’s official population estimates are compiled by the Singapore Department of Statistics. Since 2000, we adopted a register-based approach where basic population count and characteristics such as age, sex, ethnic group, type of dwelling, geographical distribution and other basic demographic statistics were obtained from multiple administrative sources.
