Citation standard
What makes a Data Lab page worth citing
The goal is not a pile of articles. Each Data Lab page needs a dataset, a clear definition, and enough source context for someone else to reuse the finding responsibly.
Downloadable data
CSVs are public and dated, so a journalist or partner can cite the exact export used for a ranking or local comparison.
Plain methodology
Definitions, sample floors, dates, and limits sit on the page beside the tables instead of being hidden in a footnote.
County-source context
Ranked county rows link back to AssessorSearch county pages, where readers can find official assessor, tax, recorder, and GIS sources.
