# 1st federal electoral district of Guerrero

The 1st federal electoral district of Guerrero (Distrito electoral federal 01 de Guerrero) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of eight such districts in the state of Guerrero.
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 fourth region.

## District territory

Guerrero lost a congressional seat in the National Electoral Institute's 2022 redistricting process. Under the new districting plan, which will be used for the 2024, 2027 and 2030 federal elections, the reconfigured 1st district is located in the state's Tierra Caliente region and covers 19 municipalities:
* Coyuca de Catalán, Ajuchitlán, San Miguel Totolapan, Apaxtla, Cuetzala del Progreso, Teloloapan, Ixcateopan, Pedro Ascencio Alquisiras, General Canuto A. Neri, Arcelia, Tlapehuala, Tlalchapa, Cutzamala, Pungarabato and Zirándaro (all included in the 2017 scheme)
* Pilcaya, Tetipac, Taxco and Buenavista de Cuéllar (new additions)
The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Ciudad Altamirano in the municipality of Pungarabato.
