Coahuila under the 2017–2022 districting plan

The 7th federal electoral district of Coahuila (Spanish : Distrito electoral federal 07 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 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 second region. ^{[2] [3]}

Suspended in 1930, ^[a] the 7th district was re-established as part of the 1977 political reforms and was first contested in the 1979 mid-term election. ^[7]

The current member for the district, elected in the 2024 general election, is Antonio Lorenzo Castro Villarreal of the National Regeneration Movement (Morena). ^{[8] [9]}

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. ^[10] The reconfigured 7th district covers 223 electoral precincts (secciones electorales) in the more rural portion of the municipality of Saltillo. ^{[11] [12] [b]}

The 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 441,607 in the 2020 Census. ^[1]

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. ^[13] The 7th district had its head town at San Pedro de las Colonias and it comprised the municipalities of Cuatrociénegas, Lamadrid, Múzquiz, Ocampo, Sacramento, San Juan de Sabinas, San Pedro and Sierra Mojada. ^[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]
2. The 4th district covers the remainder of the municipality.
3. De las Fuentes resigned his seat on 18 July 2005.
