The 7th federal electoral district of Tamaulipas (Spanish: Distrito electoral federal 07 de Tamaulipas) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of eight such districts in the state of Tamaulipas.[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]

The 7th district was created as part of the 1977 electoral reforms, which increased the state's seat allocation from six to nine. The three new districts returned their first deputies in the 1979 mid-term election.[4][5]

The current member for the district, elected in the 2024 general election, is Olga Juliana Elizondo Guerra of the Labour Party (PT).[6][7]

District territory

Tamaulipas lost a district in the 2023 districting plan adopted by the National Electoral Institute (INE), which is to be used for the 2024, 2027 and 2030 federal elections.[8] The reconfigured 7th district is in the north of the state and comprises 219 electoral precincts (secciones electorales) across six of the state's 43 municipalities:[9][10]

The head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Reynosa. The district reported a population of 383,847 in the 2020 Census.[1]

2017–2022

Between 2017 and 2022, Tamaulipas accounted for nine single-member congressional seats. Under the 2017 plan, the 7th district was in the south-east of the state. Its head town was at Ciudad Madero and it covered a portion of Ciudad Madero (65 precincts, with the remainder assigned to the 8th district) and the whole of Altamira.[12][11]

2005–2017

Under the 2005 plan, Tamaulipas had eight districts. This district's head town was at Ciudad Madero and it covered the eastern part of that municipality, plus the municipalities of Altamira and Aldama.[13][14]

1996–2005

In the 1996 scheme, under which Tamaulipas lost a single-member seat, the district had its head town at Ciudad Madero and it covered the municipalities of Aldama, Altamira and Ciudad Madero.[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, Tamaulipas's seat allocation rose from six to nine.[4] The new 7th district's head town was at Río Bravo and it covered Río Bravo, Valle Hermoso and a portion of Reynosa.[16]
