# 10th federal electoral district of Oaxaca

The 10th federal electoral district of Oaxaca (Distrito electoral federal 10 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 the district also count towards the calculation of proportional representation ("plurinominal") deputies elected from the third region.
Oaxaca's 10th district was created as part of the 1977 electoral reforms. Under the 1975 districting plan, Oaxaca had only nine congressional districts; under the 1977 reforms, the number increased to ten. The newly created district elected its first deputy, to the 51st Congress, in the 1979 legislative election.

## District territory

Under the National Electoral Institute's 2022 districting plan, which is to be used for the 2024, 2027 and 2030 federal elections, the 10th district covers 77 municipalities. The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Miahuatlán de Porfirio Díaz in the Sierra Sur region.
With Indigenous and Afrodescendent inhabitants accounting for over 63% of its population, it is classified by the National Electoral Institute (INE) as an indigenous district.

## Previous districting schemes

2017–2022 Oaxaca's 11th district was dissolved in the 2017 redistricting process. Under the 2017 to 2022 scheme, the 10th district had its head town at the city of Miahuatlán and it covered 65 municipalities.
2005–2017 Between 2005 and 2017, the district comprised 56 municipalities and its head town was Miahuatlán.
1996–2005 Between 1996 and 2017, Oaxaca's seat allocation was increased to 11. Under the 1996 districting plan, the head town was moved to Miahuatlán.
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. The new 10th district had its head town at Santo Domingo de Tehuantepec in the Istmo de Tehuantepec region.
