Under the 2005 districting scheme, it covered five municipalities: Campeche, Calkiní, Hecelchakán, Hopelchén and Tenabo.^[13][14]

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. Campeche's seat allocation, however, remained unchanged at two.^[8] The 1st district had its head town at Ciudad del Carmen and it covered the municipalities of Carmen, Champotón and Palizada.^[16]
