Dataset Inventory

Claim-status glossary for the dataset inventory
  • Headline claim: Core confirmatory rows with the strongest survey-design handling and no fallback flags. Only these rows feed the main headline claim.
  • Supporting evidence: Inferential rows kept for added age or domain coverage, but still kept separate from the main headline claim.
  • Provisional: Rows that depend on fallback weights or other temporary inference paths. They stay visible, but they do not count as headline evidence.
  • Method-limited: Rows with usable point estimates but weaker uncertainty estimates, usually because only simple effective-sample-size approximations were available.
  • QA only: Rows retained for transparency and diagnostics only, not for inferential claims.
