# 2nd federal electoral district of Sonora

The 2nd federal electoral district of Sonora (Distrito electoral federal 02 de Sonora) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of seven such districts in the state of Sonora.
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 National Electoral Institute's 2022 districting plan, which will be used for the 2024, 2027 and 2030 federal elections, the 2nd district comprises 11 municipalities in the north-eastern part of the state:
* Agua Prieta, Arizpe, Bacoachi, Cananea, Cucurpe, Fronteras, Ímuris, Magdalena, Naco, Nogales and Santa Cruz.
The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the border city of Nogales.

## Previous districting schemes
### 2017–2022

Between 2017 and 2022, the district had the same configuration as at present.

### 2005–2017

Under the 2005 plan, the district had the same configuration as in 2022 and 2017.

### 1996–2005

Under the 1996 districting plan, the head town was moved to Magdalena de Kino and the district covered the state's northern municipalities.

### 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, Sonora's seat allocation rose from four to seven. The 2nd district had its head town at the state capital, Hermosillo, and it covered a part of that city.
