# 1st federal electoral district of the State of Mexico

The 1st federal electoral district of the State of Mexico (Spanish: Distrito electoral federal 01 del Estado de México) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of 40 such districts in the State of Mexico.
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 fifth region.

## District territory

Under the National Electoral Institute's 2022 districting plan, which is to be used for the 2024, 2027 and 2030 federal elections, the 1st district covers ten municipalities in the north of the state:
* Acambay, Aculco, Chapa de Mota, El Oro, Jilotepec, Morelos, Polotitlán, Soyaniquilpan de Juárez, Temascalcingo and Timilpan.
The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Jilotepec de Molina Enríquez.
The district has a population of 418,923. With Indigenous and Afrodescendent inhabitants accounting for over 49% of that number, the first district is classified by the National Electoral Institute (INE) as an indigenous district.
