# 1st federal electoral district of Yucatán

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

Yucatán gained 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 first district is located in the east and south-east of the state. It comprises 27 municipalities:
* Cantamayec, Yaxcabá, Cuncunul, Chacsinkín, Chankom, Chemax, Chichimilá, Chikindzonot, Dzitás, Espita, Kaua, Panabá, Peto, Quintana Roo, Río Lagartos, San Felipe, Sucilá, Tahdziú, Calotmul, Tekom, Temozón, Tinum, Tixcacalcupul, Tixméhuac, Tizimín, Uayma and Valladolid.
The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Valladolid.
The district has a population of 376,469. With Indigenous and Afrodescendent inhabitants accounting for over 84% of that number, Yucatán's first – like all the state's electoral districts, both local and federal – is classified by the National Electoral Institute (INE) as an indigenous district.

## Previous districting schemes
### 2017–2022

Between 1996 and 2022, Yucatán had five federal electoral districts. Under the 2017 scheme, the first district's head town was at Valladolid and it covered 35 municipalities in the east of the state:
* Buctzotz, Calotmul, Cenotillo, Cuncunul, Chankom, Chemax, Chichimilá, Chikindzonot, Dzinzantún, Dzilam de Bravo, Dzilam González, Dzitás, Dzoncauich, Espita, Izamal, Kantunil, Kaua, Panabá, Quintana Roo, Río Lagartos, San Felipe, Sucilá, Sudzal, Tekal de Venegas, Tekom, Temax, Temozón, Tepakán, Tinum, Tixcacalcupul, Tizimín, Tunkás, Uayma, Valladolid and Yaxcabá.

### 2005–2017

Under the 2005 districting scheme, the district covered 33 municipalities in the east and south-east portions of the state and had its head town at Valladolid.

### 1996–2005

Between 1996 and 2005, the district's head town was at Valladolid and it covered an area broadly similar to its 2005 configuration, but with more of the northern coast and less of the south-eastern border with the state of Quintana Roo.

### 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, Yucatán's district allocation rose from three to four. The first district had its head town at the state capital, Mérida, and it covered a portion of that city.
