The fifth federal electoral district of Oaxaca(Distrito electoral federal 05 de Oaxaca) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of 10 such districts in the state of Oaxaca.
It elects one deputy to the lower house of Congress for each three-year legislative period, by means of the first-past-the-post system. Votes cast in this district also count towards the calculation of proportional representation ("plurinominal") deputies elected from the third region.[1][2]
Under the 2022 districting plan, which will be used for the 2024, 2027 and 2030 federal elections,[3] the fifth district covers 32 of the state's municipalities.[a]
The district's head town (cabecera distrital), where results from individual polling stations are gathered together and collated, is the port city of Salina Cruz on the Isthmus of Tehuantepec.[6]
With Indigenous and Afro-Mexican inhabitants accounting for over 64% of its population, it is officially deemed an indigenous district.[6]
Between 1996 and 2017, Oaxaca's seat allocation was increased to 11. Under the 1996 districting plan, the head town was moved to Santo Domingo Tehuantepec.[9]
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, Oaxaca's seat allocation rose from nine to ten.[10] The fifth district had its head town at Huautla de Jiménez in the Cañada region.[11]
^Oaxaca accounts for 3.3% of the country's population and 4.8% of its surface area,[4] but it contains almost a quarter of its municipalities: 570 out of 2,446.[5]
