# 7th federal electoral district of Chiapas

The 7th federal electoral district of Chiapas (Distrito electoral federal 07 de Chiapas) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of 13 such districts in the state of Chiapas.
It elects one deputy to the lower house of Congress for each three-year legislative session 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.
Suspended in 1930, the 7th district was re-established as part of the 1977 electoral reforms. Under the 1975 districting plan, Chiapas had only six congressional districts; under the 1977 reforms, the number increased to nine. The restored 7th district elected its first deputy, to the 51st Congress, in the 1979 mid-term election.

## District territory

Under the 2022 districting plan, which will be used for the 2024, 2027 and 2030 federal elections, Chiapas's 7th district covers nine municipalities along the Pacific Ocean coast and the border with the state of Oaxaca:
* Acacoyagua, Acapetahua, Arriaga, Cintalapa, Escuintla, Jiquipilas, Mapastepec, Pijijiapan and Tonalá.
The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Tonalá.

Between 2017 and 2022, the 7th district comprised nine municipalities in the same region of the state, but with some changes: Acacoyagua, Acapetahua, Arriaga, Escuintla, Huixtla, Mapastepec, Pijijiapan, Tonalá and Villa Comaltitlán.

### 2005–2017

In 2005–2017, the district was located on the Pacific coast. It comprised the municipalities of Acacoyagua, Acapetahua, Arriaga, Escuintla, Mapastepec, Pijijiapan, Tonalá and Villa Comaltitlán. The head town was the city of Tonalá.

### 1996–2005

Between 1996 and 2005, the district had a slightly different configuration in the same region. It covered Arriaga, Pijijiapan, Tonalá, Cintalapa and Jiquipilas.

### 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, Chiapas's seat allocation rose from six to nine. The restored 7th district had its head town at Huixtla and it covered 14 municipalities.
