Settlements and data processing method in the commuting network of USA. Disks of different radius \(d(i,j)\), starting from a given settlement and reaching the other j settlements, are constructed. The population \(w_{i}[j]\) inside these disks and the commuter number, starting from settlement i and traveling to settlement j, \(f_{i}(j)\), is recorded
