11th federal electoral district of Oaxaca
The 11th federal electoral district of Oaxaca (Spanish: Distrito electoral federal 11 de Oaxaca) was a Mexican federal electoral district from 1997 to 2018. During its existence, it returned one deputy to the Chamber of Deputies for each three-year legislative period by means of the first-past-the-post system. Votes cast in the district also counted towards the calculation of proportional representation ("plurinominal") deputies elected from the third region.
Oaxaca's 11th district was created as part of the Federal Electoral Institute's 1996 redistricting process, which assigned the state an additional district to the ten it already had. In the 2017 redistricting process, Oaxaca's seat allocation was again reduced to ten. The 11th district was thus first contested in the 1997 mid-term election and it elected its final deputy in the 2015 mid-terms.
