Rows share the June 30, 2025 FDIC Summary of Deposits vintage, positive branch-balance filter, county grouping, and holder-or-certificate ownership rule.
Bounded interpretation
A branch-booked county balance can differ from customer residence and competitive reach. County screens are navigation and triage evidence, not legal market definitions.

County and county-equivalent branch-deposit screens
National and within-state ranks retain the complete 2025 FDIC screen universe. County boundaries remain screening units, not asserted banking markets.
Evidence route
State context remains separately inspectable
The county layer reuses the FDIC branch records and ownership rule, while the statewide banking screen preserves its own denominator. Neither is combined with the KFF individual-insurance system.
