# 9th federal electoral district of the State of Mexico

The 9th federal electoral district of the State of Mexico (Spanish: Distrito electoral federal 09 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 9th district covers five municipalities in the west of the state, on the border with Michoacán:
* Donato Guerra, San Felipe del Progreso, San José del Rincón, Villa de Allende and Villa Victoria.
The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of San Felipe del Progreso.
The district has a population of 443,541. With Indigenous and Afrodescendent inhabitants accounting for over 63% of that number, the 9th district is classified by the National Electoral Institute (INE) as an indigenous district.
