Sourcebook

Data sources for our California injury rankings

Know what proves what. We use the most direct available authority and record the limits of every source.

Source hierarchy

Statutes, courts, State Bar, DMV, CHP, OTS, NHTSA, and official local data

Tier 2

Court records, verdict reporters, dockets, judgments, and official award-provider profiles

Tier 3

Independent review platforms and established professional directories

Tier 4

Firm websites, press releases, and retained-vendor verification reports

Tier 5–6

News for context; forums and anonymous Q&A only for questions and language

California primary sources

Traffic and local data

State and local pages use OTS, CHP SWITRS, TIMS, NHTSA FARS, and official municipal collision or Vision Zero sources. Every statistic must record the geography, period, data vintage, filter, definition, source, and whether the data is provisional.

Entity matching and attribution

Firm names, trade names, lawyers, former firms, and office locations can change. We match each claim to the entity and time period that earned it. A result follows the credited lawyer or firm; a lawyer’s recognition is not automatically treated as firmwide recognition; and an advertised service area is not recorded as a staffed office.

Dates and source snapshots

Every ranking-critical record should include a retrieval date. Review totals, office rosters, lawyer status, provider editions, and result pages can change after publication, so the visible edition date identifies the evidence window used for the ranking. Later changes are considered in corrections or the next full edition.

Known source conflicts

Government guides can themselves retain stale figures. For example, the California Department of Insurance accident guide contains older DMV damage-threshold and liability-limit figures. We use the guide for claims-process concepts but source current reporting thresholds directly from DMV and current limits from CDI.

How to inspect a firm profile

Open the linked provider profile for professional recognition, then open the firm’s result source and note whether the figure is firm-reported or supported by a public record. Use the official contact page for current office and phone information, and verify the responsible lawyer directly through the State Bar.
