This paper analyzes passengers' traffic across the border crossings and demographic trends in Croatian-Hungarian border area. The aim of this work is to determine the intensity of transborder relations and processes in neighbouring areas in the period of "loosening" of the Croatian-Hungarian border and their reflection in space. This will be determined through the analysis of the population trends in the last intercensal period (1991-2001 in Croatia, 1990-2001 in Hungary). The assumption is that significant transborder cooperation has not been established yet and that a transborder region has not been formed despite the "loosening" of the border. This statement has been confirmed by comparing demographic trends in the settlements with border crossings, in the settlements along the border, but without border crossings, in the settlements that are within 10 km from the border, but do not have an exit to it and finally, in other settlements of the border area from the Croatian and Hungarian side of the border.
