Coahuila under the 2017–2022 districting plan

The 4th federal electoral district of Coahuila (Spanish : Distrito electoral federal 04 de Coahuila) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of eight such districts in the state of Coahuila. ^[1]

It elects one deputy to the lower house of Congress for each three-year legislative session using the first-past-the-post system. Votes cast in the district also count towards the calculation of proportional representation ("plurinominal") deputies elected from the second region. ^{[2] [3]}

The current member for the district, re-elected in the 2024 general election, is Jericó Abramo Masso of the Institutional Revolutionary Party (PRI). ^{[4] [5]}

District territory

In its 2022 districting plan, which is to be used for the 2024, 2027 and 2030 federal elections, the National Electoral Institute (INE) assigned Coahuila an additional district. ^[6] The reconfigured 4th district covers 187 electoral precincts (secciones electorales) in the north-eastern, urban portion of the municipality of Saltillo. ^{[7] [8] [a]}

The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the state capital, the city of Saltillo. The district reported a population of 443,238 in the 2020 Census. ^[1]

2017–2022

Between 2017 and 2022, the district covered a part of the municipality of Saltillo and the whole of the neighbouring municipality of Arteaga. The head town was at Saltillo. ^{[11] [12]}

2005–2017

Between 2005 and 2017, the district covered the eastern portion of the municipality of Saltillo, with the city of Saltillo serving as the head town. ^{[13] [14]}

1996–2005

Under the 1996 scheme, the district covered the north-eastern portion of the city of Saltillo – the head town – together with the municipalities of Arteaga, General Cepeda, Parras and Ramos Arizpe. ^{[15] [14]}

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, Coahuila's seat allocation rose from 4 to 7. ^[9] Located in the north of the state, the 4th district had its head town at Piedras Negras and it covered the municipalities of Acuña, Jiménez, Morelos, Nava, Piedras Negras, Sabinas and Zaragoza. ^[16]
