An SMC is an electoral division that has a single Member of Parliament (MP) representing the interests of those residents in the constituency.
Thus, during a by-election in the SMC or a general election, the registered electors of the SMC will vote for a single individual to be their MP.
The Parliamentary Elections Act requires that there must be at least 8 SMCs at any time.
We currently have a total of 12 SMCs.
Group Representation Constituencies (GRCs)
A GRC is a larger electoral division, both in terms of population as well as physical area. A group of Members of Parliament (MPs) represents the interests of those residents in the constituency.
Thus, during a general election or by-election in the GRC, the registered electors of the GRC will vote for a group of individuals to be their MPs, who must be from the same political party or are all Independents.
The group may be made up of 3, 4, 5 or 6 individuals. The President declares the group number for each GRC by law.
At least one of the MPs in the group representing a GRC must belong to a minority racial community, either the Malay community or the Indian and other minority communities.
By law, the President designates the GRCs for which at least one of the MPs in the constituency must belong to one of these minority racial communities. However, the number of GRCs that can be designated as those belonging to the Malay community cannot be more than three-fifths the total number of GRCs, rounded to the next higher whole number.
The GRC system was established in 1988 to ensure that the minority racial communities in Singapore will always be represented in Parliament. To ensure this, the Parliamentary Elections Act requires that at least one-quarter of the total number of MPs must be representatives of GRCs.
Currently, there are a total of 15 GRCs, represented by a total of 75 MPs.
There are a total of 2,411,188 electors in the current registers of electors of the 27 electoral divisions, as of 1 Feb 2014 (i.e. the date the current registers of electors are based on). The registers are certified on 27 Mar 2014. The list of electoral divisions and the number of electors in each electoral division is set out below.
