Research updates

Meaningful changes, without the noise.

A record of substantive updates to published state profiles, source coverage, and the public dataset.

Latest research releases

Updates appear here when evidence, policy status, implementation timing, or downloadable data changes in a meaningful way.

  1. Independent verification

    Five state profiles independently verified

    Approved New York, Texas, Illinois, Pennsylvania, and Ohio after a fresh review of current statutes, regulations, standards, and state-agency guidance. The release corrects Illinois’s classification, clarifies covered cohorts and delivery alternatives, updates source records, and raises the verified total to seven jurisdictions.

  2. Dataset release

    Initial research release

    Published the production data model and primary-source-verified records for California and Florida. Added transparent coverage status for every remaining jurisdiction.

Built for a trustworthy change history
