Derventa

Derventa is a town and municipality of Bosnia and Herzegovina. It is sitauated in the northern part of Republika Srpska just northwest of the town of Doboj, in the Posavina region.

There are 57 villages that municipality comprises. From 1929 to 1939, Derventa was part of the Vrbas Banovina and from 1939 to 1941 of the Banovina of Croatia within the Kingdom of Yugoslavia.

Derventa's population is divided into two different categories. The first category is a demographic of the town's population solely, but on the other side, there is also another side that takes into account the town's population, but it includes all of the other settlements as well.

The previous censuses were taken during the period of SFR Yugoslavia, prior to the 1992-95 War, which would engulf the region. Like many other areas in the country the war drastically changed the composition of Derventa's population.
