Federal electoral districts of Sonora since 2023

Sonora under the 2017–2022 districting plan

The 7th federal electoral district of Sonora (Spanish : Distrito electoral federal 07 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. ^[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 first region. ^{[2] [3]}

The 7th district was created in 1978 and was first contested in the 1979 legislative election. ^[4]

The current member for the district, elected in the 2024 general election, is Alma Manuela Higuera Esquer of the National Regeneration Movement (Morena). ^{[5] [6]}

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, ^[7] Sonora's 7th district covers 205 electoral precincts (secciones electorales) across the seven municipalities in the state's south-east: ^{[8] [9]}

• Álamos, Benito Juárez, Etchojoa, Huatabampo, Navojoa, Quiriego and Rosario.

The head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Navojoa. The district reported a population of 358,031 in the 2020 Census and, with Indigenous and Afrodescendent inhabitants accounting for over 55% of that total, it is classified by the National Electoral Institute (INE) as an indigenous district – the only indigenous federal electoral district in the state. ^{[1] [a]}

Previous districting schemes

Evolution of electoral district numbers

	1974	1978	1996	2005	2017	2023
Sonora	4	7	7	7	7	7
Chamber of Deputies	196	300
Sources: [1] [4] [10] [11]

2005–2022

In the 2017 ^{[11] [12]} and 2005 ^{[13] [14]} districting plans, the 7th district had the same configuration as at present.

1996–2005

Under the 1996 plan, it covered only the five southernmost municipalities: Rosario was assigned to the 4th district, and Benito Juárez was at the time part of Etchojoa. ^{[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, Sonora's seat allocation rose from four to seven. ^[4] The newly created 7th district comprised the municipality of Cajeme. ^[16]
