How do we maintain an evidence-based hiring tracker?

Record employer, role, requisition ID, source, observed date, posted date if explicit, location, pay basis, duties, live-status evidence and interpretation. Keep “not stated” distinct from zero. Deduplicate syndicated listings by requisition; compare observation dates before calling a role newly advertised.

For future research, sample multiple employers and buyer businesses across the three target sectors. Measure counts only after defining the search universe and period. This pass intentionally does not report invented vacancy growth, average salaries or buyer budgets.
