# 1st federal electoral district of Oaxaca

The 1st federal electoral district of Oaxaca (Distrito electoral federal 01 de Oaxaca) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of 10 such districts in the state of Oaxaca.
It elects one deputy to the lower house of Congress for each three-year legislative period 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 third 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 1st district comprises 17 of the state's municipalities in the Papaloapan region. The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of San Juan Bautista Tuxtepec.
With Indigenous and Afrodescendent inhabitants accounting for over 62% of its population, it is classified by the National Electoral Institute (INE) as an indigenous district.

### 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, Oaxaca's seat allocation rose from nine to ten. The 1st district had its head town at Juchitán de Zaragoza on the Pacific coast of the Isthmus of Tehuantepec.
