# 1st federal electoral district of Baja California Sur

The 1st federal electoral district of Baja California Sur (Distrito electoral federal 01 de Baja California Sur) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of two such districts in the state of Baja California Sur.
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.

## District territory

Under the 2022 districting plan, which will be used for the 2024, 2027 and 2030 federal elections, the first district covers the municipalities of Comondú, Loreto, Mulegé, and La Paz: i.e., the entire state except for Los Cabos. 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, Baja California Sur.

## Previous districting schemes
### 2017–2002

The state's three northernmost municipalities, plus the northern portion of La Paz.

### 2005–2017

The state's three northernmost municipalities and the westernmost two-thirds of the La Paz. The district's head town was the city of Santa Rosalía, Baja California Sur.

### 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.
