Changi Single Member Constituency, simply the Changi Constituency until 1988, was a single member constituency covering Changi and eastern outer islands such as Pulau Ubin, Singapore.

Note: The Elections Department does not include rejected votes when calculating the vote shares of candidates. Hence, all candidates' vote shares will total to 100% at any given election (may not appear so in multi-way contests due to rounding).

Note 1: In 1957, Singapore Malay Union (SMU) was expelled by its alliance partners consisted of UMNO and MCA for fielding a candidate in that by-election which was the reason for the elections department of Singapore to view Fatimah as another independent candidate.

Note 2: Lim Cher Kheng was the then incumbent seeking for another term. He represented the Democratic Party (Not to be confused with the Singapore Democratic Party, which was only formed after Singapore's independence.) which was dissolved by merging with Progressive Party (Singapore) as Liberal Socialist Party within a year from the 1955 General elections. With that consideration, the vote swing for both independent candidate Lim and Liberal Socialist Party candidate Wee will be taken from Lim's previous election result because that is the result for the candidate himself and his party respectively.

Note 3: UMNO, MCA and MIC together with Singapore People's Alliance was informally formed as an alliance in 1961, where it still within this term of election which was the reason for the elections department of Singapore to view Abdul Rahman as a candidate for Singapore Alliance.

Note: One of the component party in Singapore Alliance is United Malays National Organisation (UMNO), and hence the swing will be based on its previous election of UMNO candidate.
