Method and source

Source: the Iowa insurance regulator company list, read 2026-10-18 and the surplus lines list. Admitted = Iowa Data Hub dataset 667 'Insurance Companies Licensed in Iowa' (Iowa Insurance Division, refreshed weekly, CC BY 4.0). Mixes P&C, Life, Health, State/County Mutual, Fraternal, MEWA and Benevolent entities; 'type' carries the company_type column so the merge can filter (counts: {"State Mutual": 32, "Property Casualty": 1010, "County Mutual": 22, "Health": 96, "Life": 390, "Fraternal": 28, "Benevolent": 2, "MEWA": 6}). No lines-of-authority column and no license-date column, so lines=[] and since=''. The source also has business_license_type (e.g. 'Non Iowa Stock Fire And Casualty Company', 'Non Iowa Mortgage Guaranty Insurer', 'Non Iowa HMO') and ownership_type, not carried here. Rows without an NAIC number are benevolent societies, MEWAs and captive reinsurers. Surplus lines = dataset 559 'American Surplus Lines Companies' (US-domiciled insurers not licensed in Iowa that qualified to write surplus lines); all rows have NAIC codes; alien insurers are not in this list (Iowa follows the NAIC Quarterly Listing of Alien Insurers). The surplus list has no domicile or eligibility-date column: 'domicile' here is the mailing-address state (may differ from statutory domicile) and eligible=''. Downloads are ZIPs from /api/dataset-download?path=datasets/<id>/rows.csv; data.iowa.gov robots.txt allows '*' but blocks AI crawler UAs, so a browser UA is used. Attribute: Iowa Insurance Division via data.iowa.gov (CC BY 4.0). "Premium" is direct premium written in the state for the year shown; "share" is that company's part of the state total for the line. A company can be licensed for a line and write none of it, and a surplus lines insurer can write a line without a state license for it.
