U.S. Legal & Insurance Datasets

Original, source-cited data compiled from official state statutes, agencies, and regulators. Every figure links to a primary source — nothing is published here without one.

  • Every figure cites a primary source
  • Datasets are additive — not keyword pages

What lives here

This section will hold original datasets that combine and compare official U.S. legal and insurance rules — the same material our calculators, state pages, and guides are built from. The goal is a single, trustworthy reference: each table or dataset is compiled directly from federal or state primary sources, carries its own review date and source list, and is published only when every figure can be traced to an authoritative document.

Data standards

  • Primary sources only. State legislatures, insurance departments, courts, regulatory agencies, and official federal publications. We do not build datasets from other websites' summaries.
  • No invented figures. If a number cannot be sourced and verified, it is not published. Estimated ranges are labeled as estimates with their basis stated.
  • Review dates. Every dataset records when it was last checked against current sources. Statutory or regulatory changes trigger a re-review.
  • Corrections. Errors are corrected promptly through the contact page.

Datasets in preparation

These datasets are being compiled directly from official sources and will be published as they are verified. We would rather publish fewer complete, source-cited datasets than thin approximations.

  • Minimum auto-insurance liability limits by state (official state statutes)
  • Workers' compensation maximum weekly benefit rates by state (state agencies)
  • Comparative-negligence rule map: pure, modified, and contributory states (state statutes)
  • Personal-injury statute-of-limitations deadlines by state (state codes)
  • DUI cost components by state: fines, fees, education, and insurance impact (statutes and agencies)

Until a dataset is published, the same verified information already appears wherever it is relevant — on our state rule pages and in the methodology of each calculator.

Suggest a dataset

If you work with authoritative state or federal data and would like to see a specific comparison published here, we welcome the suggestion via the contact page. Data suggestions are evaluated on source quality, reader value, and accuracy — never on keyword volume.
