Negative natural change, large emigration and population aging are key indicators that determine the demogeographic characteristics of Brod-Posavina County. The most important factors which shaped these characteristics were the Homeland War and the poor economic situation that stimulated emigration movements. The peak of the population was in 2001 when it was 176765, while in the next census in 2011 the number decreased by 10.3 %. Annual estimates from the Central Bureau of Statistics say that the population will also be reduced in the 2021 census. An important feature of the population is certainly the homogeneity, ie the fact that there is no greater mixing of ethnic or religious groups in the county. The major ethnic grup are Croatians and the major religious group are Catholics. In addition, population is not evenly spaced at the area, so that a slightly larger number of inhabitants live in the east of the county, mostly due to the nearness of Slavonski Brod as the most important center of work. Apart from Slavonski Brod, the only urban center in the county is Nova Gradiška, which, because of its smaller size, does not have as much possibilty to attract population
