5th federal electoral district of Yucatán

Yucatán gained a congressional seat in the 2023 redistricting process carried out by the National Electoral Institute (INE). Under the new districting plan, which is to be used for the 2024, 2027 and 2030 federal elections,^[7] the reconfigured 5th district is located in the south and west of the state. It comprises 186 electoral precincts (secciones electorales) across 29 municipalities:^[8][9]

• Abalá, Akil, Celestún, Chapab, Chocholá, Chumayel, Dzan, Halachó, Hunucmá, Kinchil, Kopomá, Mama, Maní, Maxcanú, Mayapán, Muna, Opichén, Oxkutzcab, Sacalum, Samahil, Santa Elena, Teabo, Tekax, Tekit, Tetiz, Ticul, Tzucacab, Ucú and Umán.

The head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Umán. The district had a population of 415,271 in the 2020 Census and, with Indigenous and Afrodescendent inhabitants accounting for over 81% of that number, Yucatán's 5th – like all the state's electoral districts, both local and federal – is classified by the INE as an indigenous district.^[1][a]

2017–2022

Between 1996 and 2022, Yucatán had five federal electoral districts. Under the 2017 scheme, the 5th district's head town was at Ticul and it covered 34 municipalities in the south and west of the state but, unlike the 2022 plan, excluding the coastal municipalities:^[13][12]

• Abalá, Akil, Cantamayec, Chacsinkín, Chapab, Chochola, Chumayel, Cuzamá, Dzán, Halachó, Homún, Huhí, Kopomá, Mama, Maní, Maxcanú, Mayapán, Muna, Opichén, Oxkutzcab, Peto, Sacalum, Sanahcat, Santa Elena, Sotuta, Tahdziú, Teabo, Tecoh, Tekax, Tekit, Ticul, Tixmehuac, Tzucacab and Umán.

2005–2017

Under the 2005 districting scheme, the district covered 33 municipalities in the west and south of the state, including the coastal municipalities to the west of Progreso. The district's head town was the city of Ticul.^[14][15]

1996–2005

Between 1996 and 2005, Yucatán's new 5th district covered a similar territory as under the 2017 scheme: without the coastal municipalities of the north-west and with a larger slice of the south of the state. The head town was Ticul and the district covered 37 municipalities.^[16][15]
