Pairing boundaryCounty rows are screens of positive FDIC Summary of Deposits branch balances grouped to the reported top bank holding company when available and otherwise to the insured institution. Branch-reported deposits may not represent where every customer lives or competes, county boundaries may not match a banking market, deposits are not every banking product, and these screens are not legal market definitions. Association between the two measures is mechanical context, not a finding about competition, access, prices, or consumer outcomes.
