The National Association of Insurance Commissioners has issued its annual Market Share Data Reports for the Property & Casualty Insurance Marketplace as well as for the Life & Fraternal Insurance Marketplace. As in the past, the data offered by the NAIC reflects a compiled list of market share data based upon filings of countrywide premium submitted to the NAIC from Property & Casualty insurers as reported on the State Page of the NAIC’s annual statement for insurers for the year 2020 (the latest date for which complete data is available).
The data is then compiled and included in various reports on cumulative market share data for the seven major lines of insurance in the United States: All lines; Private Passenger Personal Auto; Commercial Auto; Workers’ Compensation; Medical Professional Liability; Homeowners’ Multi-Peril, and Other Liability (excluding auto liability). The following is a chart using data from the NAIC which shows the Market Share by Line of Business of the top seven lines of insurance in the U.S.:
