摘要：We used two indicators in order to quantify population’s concentration level in a certain area: Lorentz curve and Gini ratio. For our research we took into account two years - 1985 and 2002, in order to compare the period previous to 1990 and the one after it. We noticed that a demographical deconcentration process caused by population decrease and disappearance of certain settlements was characteristic of the Danube Valley, in the Giurgiu and Brăila sector. We could identify eight evolution models specific to the rural settlements of this area, with four increase and four decrease models
