Every figure on PlainRegWatch is rendered from curated state legislative and Federal Register source data, no number is typed in by an editor. Figures on this page come from the curated five-category archive. See our editorial standards & corrections policy, the methodology behind these numbers, or report a data error. Primary sources: IAPP US State Privacy Legislation Tracker, National Conference of State Legislatures (NCSL), EWG food-additive tracker, Repair.org, and official state legislative records. Tracker scores and rule counts are curated records in five tracked categories - not enforcement strength, legal advice, a complete inventory of US law, or a live bill-status feed. Nothing on PlainRegWatch is legal advice; for any decision that matters, follow the primary source and consult a qualified professional (see our disclaimer).
