Midatlantic UFC - Pennsylvania-New Jersey migration flows
The top map shows the county to county flows that have a net migration FROM a Pennsylvania county TO a New Jersey county.The bottom map shows the same for flows FROM New Jersey TO Pennsylvania. So these maps isolate the inter-state migration flows between just the two states and are separated into two maps for the flows that are net into NJ or net into PA respectively. Note the flows are weighted in the width of the line symbols to the size of the net migration flow and the two maps are scaled the same for comparison. So at least for the moment Killer Keystone is stomping on Golden Garden.
