Popis:	In plotting the cases of juvenile delinquency, public relief, and mobility for an urban area, contour lines were obtained for each factor by first locating a center at the intersection of the vertical and horizontal lines which divided the spots into two equal parts. Twelve equally spaced axes were used to locate twelve points, which when connected constituted the contour line. Mobility and delinquency were closely correlated, relief distribution being differently located. The ratio to total population when plotted gave contour lines of rates. Two centers of delinquency appeared located in zones of transition or deterioration. This method present a graphic picture of the phenomena and breaks down the artificially chosen boundaries of the statistical areas.
