Deposit market share is measured at the county level from the FDIC Summary of Deposits, an annual branch-level filing as of each June 30. County data shows which institutions actually hold balances in a given market and how concentrated that market is — a question state-level totals cannot answer, because a bank can be small statewide and dominant in its home county.
