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 talled, is the state capital, the city of Saltillo. The district reported a population of 441,607 in the 2020 Census.^[1]

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.
