The 23rd federal electoral district of Mexico City (Distrito electoral federal 23 de la Ciudad de México; previously "of the Federal District") is a defunct Mexican electoral district. It was in existence from 1961 to 2023.
During that time, it returned one deputy to the Chamber of Deputies for each three-year legislative session by means of the first-past-the-post system, electing its first in the 1961 mid-term election and its last in the 2021 mid-terms. From 1979 onwards, votes cast in the district also counted towards the calculation of proportional representation ("plurinominal") deputies elected from the country's electoral regions.[1][2]
The 23rd and 24th districts were abolished in the National Electoral Institute's 2022 redistricting process because the capital's population no longer warranted that number of seats in Congress.[3]
District territory
1996–2023
Under the districting schemes in force between 1996 and 2022, the 23rd district covered different portions of the borough of Coyoacán.[4][5][6][7]
1978–1996
The districting scheme in force from 1978 to 1996 was the result of the 1977 electoral reforms, which increased the number of single-member seats in the Chamber of Deputies from 196 to 300. Under that plan, the Federal District's seat allocation rose from 27 to 40.[8]
Between 1978 and 1996, the 23rd district comprised the whole of the borough of Cuajimalpa and part of Álvaro Obregón.[9]
