Economic observatory / bounded measures
Antitrust indicator atlas
Find a measure, inspect its coverage, and follow its source records. Units, periods, and missing observations remain visible when comparing indicators.

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.
