The constituency existed in its two-seat form for three general elections and returned two Liberal PartyMembers at each election until its abolition. At abolition it was noted intense house- and apartment (tenement block-) building had occurred within its boundaries and it was divided into seven single seats.
In 1885 the two-member constituency was abolished. In 1889 the former area, for administrative purposes, became part of the London County Council local authority. In 1900 the main civil vestry was dissolved and the Metropolitan Borough of Hackney was created (with the same boundaries as the Parliamentary Borough). Since 1965 it has been part of Greater London.
Turnout, in multi-member elections, is estimated by dividing the number of votes by two. To the extent that electors did not use both their votes, the figure given will be an underestimate.
Change is calculated for individual candidates, when a party had more than one candidate in an election or the previous one. When a party had only one candidate in an election and the previous one change is calculated for the party vote.
