Guanajuato's districts in 2017–2022

The 12th federal electoral district of Guanajuato (Spanish : Distrito electoral federal 12 de Guanajuato) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of 15 such districts in the state of Guanajuato. ^[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] Guanajuato's 12th was re-established as part of the 1977 political reforms. The restored district returned its first deputy in the 1979 mid-term election. ^[7]

The current member for the district, elected in the 2024 general election, is María Magdalena Rosales Cruz of the National Regeneration Movement (Morena). ^{[8] [9]}

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, ^[10] Guanajuato's 12th district covers 216 electoral precincts (secciones electorales) in the municipality of Celaya. ^{[11] [b]}

The head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Celaya. The district reported a population of 432,575 in the 2020 Census. ^[1]

2017–2022

Between 2017 and 2022, the 12th district had the same configuration as in the 2023 plan. ^{[14] [13]}

2005–2017

Under the 2005 plan, Guanajuato had only 14 districts. This district's head town was at Celaya and it covered 188 precincts in the north and south-east of the municipality. ^{[15] [16] [c]}

1996–2005

In the 1996 scheme, under which Guanajuato was assigned 15 seats, the district had its head town at Celaya and it comprised the whole of the municipality. ^{[17] [16]}

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, Guanajuato's seat allocation rose from 9 to 13. ^[12] The new 12th district covered five municipalities in the south of the state: ^[18]

• Moroleón, Santiago Maravatío, Uriangato, Valle de Santiago (head town) and Yuriria.

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 remainder of Celaya – 32 precincts – is assigned to the 2nd district.
3. In 2005–2017, the 13th district covered the remainder of Celaya.
4. Usabiaga Arroyo resigned his seat on 28 November 2000 to take office as the federal secretary of agriculture. He was replaced for the remainder of his term by his alternate, Rivera Carranza.
