Insurance Information Institute (Triple-I) Research & Data

The Insurance Information Institute (Triple-I) Research & Data corpus is everything the industry association behind “The Trusted Voice of Risk and Insurance” publishes: plain-language explainers for every major line — auto, homeowners and renters, life, business, cyber, workers compensation — article pages that embed their own charts (the social-inflation piece carries a personal-auto-liability loss series), Issues Briefs, and the flagship Triple-I Insurance Facts compendium: thousands of facts, figures, statistical tables and charts documenting the US property/casualty industry and worldwide markets, organized into chapters on Premiums, World Insurance Markets, Surplus Lines, Motor Vehicles, Crime, and Man-made Catastrophes by Peril.

Around the compendium sit two more streams worth having in the same table: the State of the State series of state-level P&C market assessments, and The Triple-I Daily briefing of industry insights, trends, data and statistics. Hundreds of public articles and guides, plus the deepest statistical layer in US insurance commentary — mapped by Datadory into one queryable shape.

Three records, one per product family, exactly as the table returns them:

| ARTICLE_TITLE                                  | INSURANCE_LINE    | STATISTICAL_TABLE                                                              | CHART_ASSET                            | STATE_MARKET_REPORT |

Same five columns whether the row came out of an article chart, a compendium chapter or a state report — which is the point. Multiply that shape across hundreds of articles and guides, the full Insurance Facts chapter set, and the State of the State titles, and you have a single join-ready surface for US multi-line insurance commentary instead of a bookmark folder.

Five fields define each record. Two locate the subject matter — the headline and the line of business it belongs to. Two carry the quantitative payload — the tabulated figures themselves (direct premiums written, loss ratios, combined ratios, catastrophe losses) and the chart graphic when the figure ships as an image. One pins the state-level view. The statistical_table field is the heavy lifter: it holds the numbers behind every compendium chapter, keyed back to its line of business.

• Geography: United States, national and state breakdowns, plus world insurance market summaries for global context.
• Temporal: articles and briefings accumulate continuously; the Insurance Facts tables build through the year as the underlying official releases land, so recent-year figures arrive alongside the narrative around them.
• Granularity: narrative articles with embedded charts at the top, statistical tables split by line of business and by state underneath.

Your call, not ours: API, files, or your warehouse. Daily, weekly, or hourly.

Every delivery ships the complete field dictionary above, the sample rows, and the coverage profile — mapped and ready, with no integration archaeology on your side.

1. Market researchers sizing US property/casualty lines and tracking loss trends — combined ratios and catastrophe losses by peril, straight from the industry's own statistical layer.
2. Journalists and academics citing insurance statistics with confidence — the corpus is the default quotation source for US P&C figures, and the mapped table makes every citation retrievable.
3. Product and strategy teams at carriers and insurtechs scanning line-level commentary and state market assessments to decide where a new product or territory case is worth building.
4. Data scientists joining premium, loss-ratio and catastrophe series onto claims, portfolio or pricing tables keyed on line of business and state.

This corpus is industry-association research: what the market wrote about itself and the statistics behind the writing. It is not the whole picture. Regulatory filings and department-level publications live in the NAIC's resource center, economy-wide insurance and financial indicators sit in World Bank WDI, and the European equivalent of this commentary layer lives in the EU Open Data Portal. Pair them and association narrative meets regulatory record meets macro frame.

Notes and adjacent reading:

• NAIC Resource Center — Regulatory Data & Publications — the regulatory counterpart: state department filings and publications to set against association research.
• World Bank WDI — Insurance & Financial Indicators — cross-country insurance penetration and financial-series context for the world-markets chapters.
• EU Open Data Portal Search — Insurance Datasets — the European institutional layer, useful when the world insurance market summary needs a primary source.
