The concept of disparity and its paradigm Etymologically, the word comes from the Latin word disparilitas for which the Romanian-Latin Dictionary (Guţu, Gh., 1983, p. 356) records the meaning of dissimilarity, difference. Consequently, various dictionaries note that the notion of disparity names an "inequality, difference, lack of similarity, heterogeneity" (Le Petit Robert, 1991, p. 552, cf. Ancuţa, 2010). Numerous studies which present one aspect or another of the management or functioning of territorial ensembles assume as self-evident that the term indicates an inequality. However, in the case of geographical studies, has to be done a supplementary specification, indicating that this term is not related to just any inequality, but to an inequality "felt, perceived and lived as an injustice" (Brunet, Ferras, Thery, 1992, cf. Ancuţa, idem). This inequality may correspond to a difference in different areas-social, economic, cultural, etc.but it is important to specify that we are dealing with disparities if the differences reach high values, having an impact on the functioning of the territorial system and on the development of the economy (George, 1980, cf. Ancuţa, ibid).
