The district was in the north of the state and covered the municipalities of Acaponeta, El Nayar, Huajicori, Rosamorada, Ruiz, Santiago Ixcuintla, Tecuala and Tuxpan; i.e., the 2023 configuration without San Blas (assigned to the 3rd district). The head town was at Santiago Ixcuintla.^[12][13]

1996–2005

Between 1996 and 2005, the district covered seven municipalities: the same territory as in the 2005 plan, with the exception of the municipality of El Nayar, which belonged to the 2nd district.^[14][13]

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, Nayarit's seat allocation rose from two to three.^[15] The 1st district had its head town at Tepic and it covered the municipalities of El Nayar, Rosamorada, Tepic and Tuxpan.^[16]
