Why these 12 sources
Government primary sources are the citation tier where the data is the publication. Census filings, regulatory disclosures, central-bank statistics, climate assessments — these are not summaries of evidence but the evidence itself. The 12 below combine that primary-source authority with strong open-data APIs and high tier-1 citation velocity.
