Counting sounds trivial until you try. The same role appears on several boards; one requisition may advertise four seats; an agency and an employer may both advertise the same job. Each choice changes every downstream number.
Our rule
One posting is one role at one employer in one location, regardless of how many places it appears.
What follows from it
| Situation | How we count | Consequence |
|---|---|---|
| One role on five boards | 1 | Counts reflect roles, not listings |
| One requisition, four seats | 1 | We undercount multi-seat hiring |
| Same title, two cities | 2 | Geographic cuts stay meaningful |
| Employer and agency both advertise | 1, marked as agency-sourced | Agency involvement stays visible |
| Role reposted six months later | 2 | A new requisition is a new posting |
The one we get wrong on purpose
Multi-seat requisitions are undercounted. A company opening one requisition for six warehouse staff counts once here, and as six openings in official vacancy statistics. We chose predictable undercounting over invisible overcounting, because a duplicate-inflated count cannot be corrected after the fact by anyone reading it.
If you are comparing our counts to an official series, this is the main reason they will differ, and the gap will be largest in high-volume hiring.
How to check us
Pick an employer whose careers page you can read. Count their open roles by hand. Compare with what we report. If the numbers diverge by more than a few percent, we want to know — that is exactly the sort of correction the feedback form exists for.
