23rd federal electoral district of Mexico City

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 2022.

Mexico City under the 2017–2022 districting plan

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 by the National Electoral Institute (INE) in its 2023 redistricting process because the capital's population no longer warranted that number of seats in Congress.^[3]

1996, 2005 and 2017

Under the three districting schemes in force between 1996 and 2022, the 23rd district covered different portions of the borough of Coyoacán.^{[7][8][9][10]}

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.^[4] Between 1978 and 1996, the 23rd district comprised the whole of the borough of Cuajimalpa and part of Álvaro Obregón.^[11]
