Jalisco's districts in 2017–2022

The 20th federal electoral district of Jalisco (Spanish: Distrito electoral federal 20 de 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.[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 first region.[2][3]

Suspended in 1930,[a] the 20th district was re-established as part of the 1977 electoral reforms. It was suspended again in 1996 but restored by the National Electoral Institute (INE) in its 2017 redistricting.

The current member for the district, elected in the 2024 general election, is Katia Alejandra Castillo Lozano of the National Regeneration Movement (Morena).[7][8]

District territory

Under the National Electoral Institute's 2023 districting plan, which is to be used for the 2024, 2027 and 2030 federal elections,[9] Jalisco's 20th district is located in the Guadalajara Metropolitan Area and comprises 52 electoral precincts (secciones electorales) across two of the state's 125 municipalities:[10]

The head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Tonalá. The district reported a population of 400,804 in the 2020 Census.[1]

2017–2022

The 20th district was restored in the 2017 redistricting process. Its head town was at Tonalá and it covered 90 precincts across five municipalities in the centre of the state:[14][13]
  • Acatic, Juanacatlán, El Salto, Tonalá (part) and Zapotlanejo.

1996–2017

Between 1996 and 2017, Jalisco had only 19 congressional seats.

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.[11] The 20th district's head town was at Zapopan and it covered a part of the city, a part of its surrounding municipality, and the whole of the neighbouring municipality of Tala.[15]

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 bulk of Tonalá (69 precincts) is assigned to the 7th district.
