The concentration-per-population index is the Gini index. High values of the indicator show a high spatial concentration of flows, and low values show a low spatial concentration of flows in a given region.
The synthetic relationship matrix for 11 flows shows the mosaic spatial pattern for the concentration-per-population indicator. A clearly higher concentration is characteristic of northern Europe, Great Brit-ain, Ireland, Switzerland, Hungary, Slovakia, and Greece, as well as rural and peripheral centers, while metropolises, including capitals, are usually characterized by a large spatial diversification of flows and networks of flows. Especially low values of the indicator, which mean a high dispersion of flows, are characteristic of Andalusia, Valencia, and Catalonia in Spain, of southern France, and of northern Italy. The box-plot analysis confirms the above conclusions. Rural regions (low total FUA populations), less-developed regions, and regions remaining outside the EU (the result, in this case, of a high concentra-tion of flows in Norway, Great Britain, and Switzerland) are characterized by a particularly high spatial concentration.
