Baja California Sur under the 2017–2022 districting plan

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]

The current member for the district, elected in the 2024 general election, is Manuel Alejandro Cota Cárdenas of the National Regeneration Movement (Morena).^[4][5]

District territory

Under 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 first district covers 355 electoral precincts (secciones electorales) across the municipalities of Comondú, Loreto, Mulegé, and La Paz: i.e., the entire state except for Los Cabos at the southern tip of the peninsula.^[7]

The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the state capital, the city of La Paz. The district reported a population of 447,347 in the 2020 Census.^[1]

Previous districting schemes

Evolution of electoral district numbers

	1974	1978	1996	2005	2017	2023
Baja California Sur	2	2	2	2	2	2
Chamber of Deputies	196	300
Sources: [1][8][9][10]

2017–2022

The state's three northern municipalities (Comondú, Loreto and Mulegé), plus the northern portion of La Paz. The head town was La Paz.^[11][10]

2005–2017

The state's three northern municipalities and the westernmost two-thirds of the La Paz. The district's head town was the city of Santa Rosalía.^[12][13]

1996–2005

The state's three northern municipalities only, with the head town at Santa Rosalía.^[14][13]

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. Baja California Sur's seat allocation, however, remained unchanged at two.^[8] The 1st district had its head town at La Paz and covered that city and its municipality.^[15]

Pre-1974

Before Baja California Sur acquired statehood in 1974 and was still a federal territory, it was entitled to return only one deputy to Congress; the district known as the sole district of the Southern Territory of Baja California (Distrito único del Territorio Sur de Baja California) therefore covered the whole of modern-day Baja California Sur. The state's first district is considered the successor of the territory's sole district.
