18th federal electoral district of Veracruz

Veracruz lost a congressional district in the 2023 districting plan adopted by the National Electoral Institute (INE), which is to be used for the 2024, 2027 and 2030 elections.^[9] The reconfigured 18th district covers 217 electoral precincts (secciones electorales) across 25 municipalities in the state's Mountains region:^[10][11]

• Acultzingo, Aquila, Astacinga, Atlahuilco, Camerino Z. Mendoza, Coetzala, Cuichapa, Los Reyes, Magdalena, Maltrata, Mixtla de Altamirano, Naranjal, Nogales, Omealca, Rafael Delgado, San Andrés Tenejapan, Soledad Atzompa, Tehuipango, Tequila, Texhuacan, Tezonapa, Tlaquilpa, Tlilapan, Xoxocotla and Zongolica.

The head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Zongolica. The district reported a population of 423,573 in the 2020 Census and, with Indigenous and Afrodescendent inhabitants accounting for over 62% of that total, it is classified by the INE as an indigenous district.^[1][12][a]

Because of shifting demographics, Veracruz currently has four fewer districts than the 23 the state was allocated under the 1977 electoral reforms.^[13]

2017–2022

Between 2017 and 2022, Veracruz was assigned 20 electoral districts. The 18th district comprised 26 municipalities: the same 25 as under the 2023 plan, plus Huiloapan de Cuauhtémoc, which the 2023 scheme assigned to the 15th district.^[11] Its head town was the city of Zongolica.^[15][14]

2005–2017

Veracruz's allocation of congressional seats fell to 21 in the 2005 redistricting process.^[13] Between 2005 and 2017 the 18th district had its head town at Zongolica and it comprised 24 municipalities in the same region as the later schemes:^[16][17]

• Acultzingo, Astacinga, Atlahuilco, Camerino Z. Mendoza, Coetzala, Cuichapa, Cuitláhuac, Huiloapan de Cuauhtémoc, Magdalena, Mixtla de Altamirano, Omealca, Rafael Delgado, Los Reyes, San Andrés Tenejapan, Soledad Atzompa, Tehuipango, Tequila, Texhuacan, Tezonapa, Tlaquilpa, Tlilapan, Xoxocotla, Yanga and Zongolica.

1996–2005

Under the 1996 districting plan, which assigned Veracruz 23 districts, the head town was at Zongolica and the district covered 19 municipalities.^[18][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, Veracruz's seat allocation rose from 15 to 23.^[4] The newly created 18th district had its head town at Temapache in the state's northern Huasteca Baja region and it covered the municipalities of Álamo Temapache, Castillo de Teayo and Tihuatlán.^[19]
