Collier County carrier presence
Residential carriers writing in Collier County, ranked by policies in force, from the OIR QUASR county cut (as of 2026-03-01).
Florida's largest domestic insurers file county-level data as trade secret under §624.4212, Fla. Stat. (e.g. State Farm Florida, Universal, Slide, Tower Hill, American Integrity, Florida Peninsula, Kin). They are absent from this county view, so treat it as the residual-and-specialty slice of the market, not the whole.

Methodology & sources
This explorer compiles filed and public-record insurance market data. It is a reference surface, not insurance advice — figures reflect what carriers and regulators have filed, with the vintage shown per source.
- Carrier market shareNAIC 50-state baseline + state DOI reports (latest filed year)
- Carrier market-share is computed within a single state and line from filed market data (NAIC 50-state baseline, state DOI market-share reports, and FL OIR QUASR). Share compares carriers inside one state/line only — it never sums premium across states, so earned-basis and written-basis filings are never mixed.
- Florida county presenceFL OIR QUASR county cut, latest report period
- Florida county carrier presence is the OIR QUASR county cut. Large Florida domestic carriers file their county data as trade secret under §624.4212, Fla. Stat., so they are absent here — the county view is not a complete market.
- Residual marketIII / PIPSO residual-plan stats (FY2024) + state factbooks
- Residual-market exposure aggregates FAIR plans, beach/windstorm pools, and state-run insurers of last resort from Insurance Information Institute (III · PIPSO) stat tables and state factbooks. Exposure and premium are stored in full dollars.
- Carrier-health watchNAIC GRID + state insolvency lists
- Receivership status is from NAIC GRID and state insolvency lists. We show the proceeding type and date as filed — this is a public record, not a judgment about a carrier's financial strength.
- ZIP cost & nonrenewalFIO federal homeowners filings, 2018–2022
- ZIP-level premium, loss, and nonrenewal figures are from the Federal Insurance Office (FIO) homeowners data filings, 2018–2022. Treasury withdrew the dataset; this is a recovered public mirror.
- Utah basis note
- Utah filings report direct premiums earned (not written); its share figures are earned-basis and not directly comparable to written-basis states.
