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]
The current member for the district, re-elected in the 2024 general election, is Brígido Ramiro Moreno Hernández of the Labour Party (PT).[4][5]
District territory
In its 2023 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 1st district comprises 206 electoral precincts (secciones electorales) across six municipalities in the state's extreme north:[7][8]
The head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Piedras Negras. The district reported a population of 403,123 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.[9] The 1st district had its head town at Saltillo and it covered that city.[16]
