12th federal electoral district of Jalisco

The 12th federal electoral district of Jalisco () is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of 20 such districts in the state of Jalisco.

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.

The current member for the district, elected in the 2024 general election, is Sandra Beatriz González Pérez of the National Regeneration Movement (Morena).

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, Jalisco's 12th district covers parts of two of the state's 125 municipalities:

The head town (), where results from individual polling stations are gathered together and tallied, is the city of Santa Cruz de las Flores in Tlajomulco. The district reported a population of 441,598 in the 2020 Census.

Previous districting schemes

2017–2022

Jalisco regained its 20th congressional seat in the 2017 redistricting process. The 12th district's head town was at Santa Cruz de las Flores and it covered the 129 precincts that made up the municipality of Tlajomulco.

2005–2017

Under the 2005 plan, Jalisco had 19 districts. This district's head town was at Tlajomulco and it covered 35 precincts in that municipality, 41 precincts in the municipality of Tlaquepaque, and the whole of El Salto.

1996–2005

In the 1996 scheme, under which Jalisco lost a single-member seat, the district covered 186 precincts in the west of the municipality of Guadalajara.

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, Jalisco's seat allocation rose from 13 to 20. The 12th district's head town was at Ameca and it covered a number of municipalities in the west of the state, including Puerto Vallarta, San Martín de Hidalgo, San Marcos and San Sebastián.
