Reading this. Each branch is counted in the county where it physically sits. Deposits are what each branch reports to the FDIC — for retail-heavy banks this tracks roughly with local economic activity, but a money-center branch can hold deposits from out-of-state corporate accounts. The institution count reflects distinct FDIC certificates, not brand-level rollups (e.g., several regional brand-names may roll up to one FDIC cert).
