The essence of the social and geographical system local classifications was revealed. They include indicators of system development (indexes sum of the social and geographical system statistical parameters; projection square of the social and geographical system state in the multidimensional space on plane (by the graph-analytical method), development uniformity; information entropy, given information entropy) and development dynamic – trajectory parameters (cosine of an angle between social and geographical system trajectory and optimal trajectory; distance traveled by a social and geographical system in the multidimensional feature space (L); distance between the current point and the minimal development point (coordinates beginning) (L0); distance from the current point to the maximum development point (end point) (L1); progress coefficient). Among cities of regional subordination the city ofKharkivis highlighted by system development indicators, since it is the biggest city in the region, characterized the highest level of socio-economic development.
