The topic of the present methodological dissertation is the examination of Hungarian territorial differences in the context of modernization and development. In the background of my choice of topic lies the scientific importance of the issue, the growing domestic quantitative research and the illumination of the Trianon trauma from a new perspective (Demeter 2018, Szilágyi 2018). I also consider this to be a novel approach, because it is a fact that June 4, 1920 significantly affected our country in all areas, but approaches have come to light (Tomka 2018) that already paint a more nuanced picture of Trianon and the subsequent economic downturn. So I consider it justified to carry out an empirical research on a quantitative basis with the involvement of the settlement network. Thus, we can approach the relationship between development and Trianon from new perspectives. Writing of which, the 100th anniversary itself is another motivation.
