Pick a state to see how concentrated its banking and individual health-insurance markets are, how that has changed, and how it compares with its neighbors. Each series has its own history and source; state lines are not market boundaries.
Place the latest Census business-application field beside separately bounded FDIC branch-deposit and KFF individual-insurance screens across every state jurisdiction, with no composite score.
Compare individual-insurance concentration with a reproducible statewide FDIC branch-deposit screen, then inspect the exact state record behind either layer.

Fixed Broadband Concentration
Follow 36 FCC HHI observations from Dec 2020 through Dec 2024. National concentration rose while the median state, county, and census-tract summaries fell over the same endpoint comparison.
3,104 county and county-equivalent rows preserve the 2025 FDIC branch-deposit denominator, holder-or-certificate grouping, fixed ranks, and exact FIPS profile handoffs.
This geography layer describes the ACA-regulated individual health insurance market using KFF's 2024 state-level measures. It does not measure a state's overall economy, employer-sponsored insurance, or a legal market definition. The FDIC banking layer above is a separate statewide deposit screen with its own source, period, ownership aggregation, and local-market caveat.
