# 4th federal electoral district of Yucatán

The 4th federal electoral district of Yucatán (Distrito electoral federal 04 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.
Created as part of the 1977 electoral reforms, it was first contested in the 1979 mid-term election.

## 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 4th district comprises 137 electoral precincts (secciones electorales) in the north of the municipality of Mérida.
The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the state capital, the city of Mérida.
The district has a population of 390,688. With Indigenous and Afrodescendent inhabitants accounting for over 43% of that number, Yucatán's 4th – 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 4th district's head town was at Mérida and it covered 230 precincts in the north of the municipality.

### 2005–2017

Under the 2005 districting scheme, the district covered 211 precints in the south and north-eastern portions of the municipality of Mérida, with the city of Mérida as its head town.

### 1996–2005

Between 1996 and 2005, the district covered the eastern portion of the municipality of Mérida, with the city of Mérida as its head town.

### 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 newly created 4th district had its head town at Mérida and it covered part of the city, the rural portion of the municipality of Mérida, and a series of neighbouring municipalities.
