16th federal electoral district of the State of Mexico

The 16th federal electoral district of the State of Mexico (Spanish: Distrito electoral federal 16 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.^[1]

Federal electoral districts of the State of Mexico since 2022

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.^[2][3]

Suspended in 1930,^[a] the 16th district was re-created by the 1977 electoral reforms, which increased the number of single-member seats in the Chamber of Deputies from 196 to 300. Under that plan, the State of Mexico's seat allocation rose from 15 to 34.^[7] The new districts were first contended in the 1979 mid-term election.

District territory

Under the National Electoral Institute's 2022 districting plan, which is to be used for the 2024, 2027 and 2030 federal elections,^[8] the 16th district is located in the Greater Mexico City urban area, covering portions of two of the state's 125 municipalities:

• Ecatepec de Morelos (south-western portion) and Tlalnepantla de Baz (eastern exclave).^[9][10][b]

The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Ecatepec. In the 2020 Census, the district reported a total population of 401,345.^[1][11]

Notes

1. An amendment to Article 52 of the Constitution in 1928 changed the original provision of "one deputy per 60,000 inhabitants" to "one deputy per 100,000";^[4][5] as a result, the size of the Chamber of Deputies fell from 281 in the 1928 election to 171 in 1934.^[6]
2. The remainder of Ecatepec is covered by the 10th, 11th, 13th and 17th districts; the remainder of Tlalnepantla is covered by the 19th district.
