Tamaulipas's districts in 2017–2022

The 1st federal electoral district of Tamaulipas (Spanish: Distrito electoral federal 01 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 current member for the district, elected in the 2024 general election, is Carlos Enrique Canturosas Villarreal of the Ecologist Green Party of Mexico (PVEM).^[4][5]

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;^[6] the 1st district, however, was not affected. It covers the entirety of the municipality of Nuevo Laredo in the state's extreme north.^[7][8]

The head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Nuevo Laredo. The district, comprising 210 electoral precincts (secciones electorales), reported a population of 425,055 in the 2020 Census.^[1]

2017–2022

Between 2017 and 2022, Tamaulipas accounted for nine single-member congressional seats. The 1st district's head town was at Nuevo Laredo and it covered that city and its surrounding municipality (206 precincts).^[12][11]

2005–2017

Under the 2005 plan, Tamaulipas had eight districts. This district's head town was at Nuevo Laredo and it covered 208 precincts across five municipalities:^[13][14]

• Camargo, Guerrero, Mier, Miguel Alemán and Nuevo Laredo.

1996–2005

In the 1996 scheme, under which Tamaulipas lost a single-member seat, the district had its head town at Nuevo Laredo and it comprised six municipalities:^[15][14]

• Camargo, Guerrero, Mier, Miguel Alemán and Nuevo Laredo as in the 2005 plan, plus Gustavo Díaz Ordaz.

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.^[9] The 1st district covered the municipality of Nuevo Laredo.^[16]
