Then, on 1 January 1871, the northeastern part of the municipality (population: 1,384) was separated from Ibestad to form the new Salangen Municipality. This left Ibestad with 4,301 inhabitants. On 1 January 1907, the easternmost area of Ibestad (population: 1,536) became the separate Lavangen Municipality. Ibestad had 5,709 residents remaining after the split. In 1926, the municipality of Ibestad was divided into four separate municipalities: Andørja (population: 1,420) in the northeast, Gratangen (population: 1,967) in the southeast, Astafjord (population: 1,018) in the southwest, and (a much smaller) Ibestad (population: 1,768) in the northwest.
