Yucatán under the 2017–2022 districting plan

3rd district in 2005–2017

It elects one deputy to the lower house of Congress for each three-year legislative period 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 third region.^[2][3]

The current member for the district, elected in the 2024 general election, is Óscar Iván Brito Zapata [es] of the National Regeneration Movement (Morena).^[4][5]

District territory

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,^[6] the 3rd district comprises 191 electoral precincts (secciones electorales) in the south of the municipality of Mérida.^[7][8][a]

The head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the state capital, the city of Mérida. The district had a population of 372,609 in the 2020 Census, and with Indigenous and Afrodescendent inhabitants accounting for over 43% of that total, Yucatán's 3rd – like all the state's electoral districts, both local and federal – is classified by the INE as an indigenous district.^[1][b]

2017–2022

Between 1996 and 2022, Yucatán had five federal electoral districts. Under the 2017 scheme, the 3rd district's head town was at Mérida and it covered 240 precincts in the south of the municipality.^[12][11]

2005–2017

Under the 2005 districting scheme, the district covered 192 precints in the north-western portion of the municipality of Mérida, with the city of Mérida as its head town.^[13][14]

1996–2005

Between 1996 and 2005, the district covered the western portion of the municipality of Mérida, with the city of Mérida as its head town.^[15][14]

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, Yucatán's district allocation rose from three to four.^[9] The 3rd district had its head town at Temax in the northern part of the state.^[16]

Notes

1. The 4th and 6th districts cover the remainder of the municipality.
2. Population figure indicates total inhabitants, not voters. The INE deems any electoral district where Indigenous or Afrodescendent inhabitants number 40% or more of the population to be an indigenous district.^[1]
3. Araujo Lara resigned her seat on 6 January 2010 to contend (successfully) for the municipal presidency of Mérida.
4. Aguilar Salazar was elected for the seat but died on 5 September 2018 before he could be sworn in.^[35] Interián Gallegos, his substitute, served the 2018–21 term in his stead.^[36]
