According to the government, alarm over a low birthrate prompted the creation of the SDU in 1984.
But to many Singaporeans, the SDU's focus on "educated" singles is nothing short of social engineering: an effort to preserve the current racial balance between the city's Chinese majority and the Malays, who tend to be less educated.
It can be a form of courtship that consists of social activities done by the couple.
When it was first established in 1984 as SDU, it functioned on its own, organising activities for its members without the help of commercial agencies.
It was only in 2006 that the then SDU decided on a major change in approach: it let the private sector be the main provider of matchmaking and dating services, focusing instead on accrediting and funding private dating agencies and projects.
This was done in the hopes of creating a more vibrant dating scene and of allowing singles to have more options to interact with others of different educational levels.
A census conducted in 1980 revealed that a large number of highly educated women were still unmarried, despite being above 40 years of age.
