8th district in 2005–2017

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 first region.^[2][3]

The 8th district was created as part of the 1977 electoral reforms. Under the 1975 districting plan, Chihuahua had only six congressional districts;^[4] with the 1977 reforms, the number increased to ten.^[5] The newly created district elected its first deputy in the 1979 mid-term election.

The current member for the district, elected in the 2024 general election, is César Alejandro Domínguez Domínguez [es] of the Institutional Revolutionary Party (PRI).^[6][7]

District territory

Under the 2023 districting plan adopted by the National Electoral Institute (INE), which is to be used for the 2024, 2027 and 2030 federal elections,^[8] the 8th district covers 377 electoral precincts (secciones electorales) in the southern part of the municipality of Chihuahua and the eastern part of the city of Chihuahua.^[9][10]

The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Chihuahua. The district reported a population of 468,890 in the 2020 Census.^[1][10]

2017–2022

Between 2017–2022 the 8th district covered the east and south of the city of Chihuahua and the south of the municipality of Chihuahua.^[12][13]

2005–2017

Under the 2005 districting scheme, the district comprised the eastern and northern portions of the municipality of Chihuahua, including approximately one-half of the urban area of the city of Chihuahua. The head town was the city of Chihuahua. The other half of the city, and the rest of the municipality, was covered by the 6th district.^[14][15]

1996–2005

Chihuahua lost its 10th district in the 1996 redistricting process. Between 1996 and 2005, the 8th district covered the southern portion of the municipality of Chihuahua, the part south of the Río Chuvíscar.^[16][15]

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, Chihuahua's seat allocation rose from six to ten.^[4] The new 8th district covered the urban area of Ciudad Juárez in the north of the state.^[17]
