List of electoral divisions and wards in Singapore

From Wikipedia, the free encyclopedia

The list of all the constituencies and electoral divisions that have been present in Singapore, as well as changes made in each division over the years in Singapore's history.

There are divisions that have been available from the past to present, although some divisions have been renamed over the years due to population changes. In the first-ever elections of Singapore in 1948, it was simplified to just four divisions, the two-seat Municipal North-East and South-West constituencies, and the single-seat Rural East and Rural West constituencies.[1]

The British authorities tabled an amendment on redistricting the constituency boundaries within Singapore based on municipal districts to reflect population distribution more accurately and to facilitate political contestation within clearer geographic divisions, while removing joint districts. These changes were enacted in 1951 and resulted in the formation of nine constituencies, all single-seats at the time, which later collectively known as Single Member Constituencies (SMC).[2] The number of seats subsequently expanded over the years while Chamber of Commerce were abolished in 1959. The team that oversees the redistricting process would later be called Electoral Boundaries Review Committee (EBRC), which were responsible to maintain even distribution across voters in each election.[3]

On 1 June 1988, the Parliament enacted the creation of Group Representation Constituencies, which was used in the subsequent election held three months later, to ensure the ethnic representation and the Town Council scheme, which was earlier enacted in 1986.[4][5] Under the current Parliamentary Elections Act, the map requires at least one-quarter of the total seats to be allocated as GRCs and to have at least eight SMCs at any time. In that election, 36 (or approximately 45%) of the 79 seats were redistricted into 13 three-member GRCs with the creation of additional SMCs, leaving with 42 SMCs on the map.[6] Subsequent elections raised the GRCs seats to a size between four and six and the SMCs were drastically reduced; in 1991, there were 15 (all) four-member GRCs and 21 SMCs, then in 1997, only nine SMCs remain while the other 74 (approximately 89%) seats were consolidated among 15 GRCs (an average of 4.93 seats). The average size of each GRCs peaked at 5.36 in the 2000s (while also have nine SMCs as well and absence of four-member GRCs), while beginning a practice where a few existing GRCs (between two and five) had no changes in the electoral boundaries, but this was lowered in subsequent elections starting in 2011 due to the increase of parliamentary seats and SMCs under the Prime Minister's advice to EBRC, and by 2015, that average size surpassed those of 1997's size at 4.75 while the number of SMCs and GRCs were gradually increased as well, and these changes persist in subsequent elections, culminating to the elimination of six-member GRCs beginning in the 2020 election.[7][8] Conversely, divisions are also formed but most of the divisions had never carved out as an SMC on its lifetime or were renamed.

As of the 2025 revision of boundaries, there were 196 divisions and 37 Group Representation Constituencies (GRC) created in total. Per consistency reasons, the 13 GRCs that either had double-barrelled names or as an entire place of GRC, were not considered as a division and therefore these are being excluded from the list.[a]
