Primary-source datasets
Research begins with attributable government records, statutes, agency publications, and documented methodology.
Evidence desk
Research designed to show its work.
This desk will publish original analysis only when the source data, method, limitations, and update history can be shown clearly. We are not filling the page with unsupported statistics while that work is underway.
Reproducible review
Published findings will identify the period examined, definitions used, exclusions, and material limitations.
Independent interpretation
Commercial relationships do not determine findings, rankings, or the selection of evidence.
