- Indicator id: `fdic_insured_institutions`
- Place id: `us-state-17`
- Unit: count
- Definition: Number of FDIC-insured commercial banks and savings institutions at year end, counted in the state where each institution has its headquarters.
- Note: FDIC historical summary of insured institutions, year end, for the 50 states and DC; the national value covers the same area and excludes US territories. Each value adds commercial banks and savings institutions, which the FDIC reports separately; both figures are stored with it. Credit unions are not FDIC-insured and are not included. An institution with branches in several states counts once, in its headquarters state, so the number of banks operating in a state can be higher. The series starts in 1984, when savings institutions enter the FDIC summary.
