Reading this. An institution's branches in a state are the physical locations it operates there — separate from where the institution is headquartered. JPMorgan Chase, for example, is HQ'd in Ohio for regulatory purposes but operates branches in nearly every state. Deposits reflect what's booked at each branch — not necessarily where the depositor lives.
