Chiapas under the 2017–2022 districting scheme

7th district in 2005–2017

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.^[2][3]

Suspended in 1930,^[a] the 7th district was re-established as part of the 1977 electoral reforms. Under the 1975 districting plan, Chiapas had only six congressional districts;^[7] with the 1977 reforms, the number increased to nine.^[8] The restored 7th district elected its first deputy in the 1979 mid-term election.

The current member for the district, elected in the 2024 general election, is Azucena Arreola Trinidad of the National Regeneration Movement (Morena).^[9][10]

District territory

Under the 2023 districting plan adopted by the National Electoral Institute (INE), which is to be used for the 2024, 2027 and 2030 federal elections,^[11] Chiapas's 7th district covers 214 electoral precincts (secciones electorales) across nine municipalities along the Pacific Ocean coast and the border with the state of Oaxaca:^[12][13]

• Acacoyagua, Acapetahua, Arriaga, Cintalapa, Escuintla, Jiquipilas, Mapastepec, Pijijiapan and Tonalá.

The head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Tonalá. The district reported a population of 435,249 in the 2020 Census.^[1]

2005–2017

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.^[15]

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.^[16]

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.^[17]

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.^[18] The restored 7th district had its head town at Huixtla and it covered 14 municipalities.^[19]

Notes

1. An amendment to Article 52 of the Constitution in 1928 changed the original provision of "one deputy per 60,000 inhabitants" to "one deputy per 100,000";^[4][5] as a result, the size of the Chamber of Deputies fell from 281 in the 1928 election to 171 in 1934.^[6]
