The Independent Insurance Agents of Wisconsin are offering a complimentary copy of our 2024 Q2 Property-Casualty WI Marketplace Report to all IIAW agency members and Silver, Gold, Diamond and Exclusive Supporting Members. This report offers a Wisconsin-specific P&C Marketplace summary that highlights top lines of business, agent penetrations, loss ratios, percentage of surplus lines and the biggest writing insurers. The data is a deep-dive into the insurer industry data for the state of WI from an independent agent's point-of-view. The goal is to provide a baseline of our state's marketplace that can be very useful in your agency for planning purposes. Agents can see the large writers overall, those insurers using agents and writing as surplus lines, and premium & loss ratio trends.
