Under to Section 377A of the Penal Code of Singapore, sex between males is illegal. While this law is rarely enforced in Singapore, this makes efforts to estimate the SGM population very difficult and limited. However, a 2019 study conducted by researchers at the National University of Singapore’s Saw Swee Hock School of Public Health estimated that there are 210,000men who have sex with men in Singapore. This may provide an insight on one aspect of SGM. There is also very little information surrounding population estimates of other SGM individuals.
