Reports
A numbered series. Each report states its own version and date, keeps its address permanently, publishes the data behind it, and says what it cannot answer as carefully as what it can.
Nothing has been published in this series yet. The first report is listed below with its scope and its limits so that what it will and will not claim is on the record before it is written, rather than after.
This page is not indexed until there is something on it to read.

Establishing the Record
What a job posting archive can and cannot say in its first weeks.
The archive these reports are drawn from
These figures are 16 days old, and so is the count itself: we last totalled the record on September 20, 2026. The crawl may have run since. We are showing the last complete count rather than a partial one.
| Employers on the entity spine | 240,505 |
|---|---|
| Employers with observed job postings | 1,089 |
| Job postings in the record | 295,482 |
| Individual observations recorded | 429,838 |
| Distinct days observed | 31 |
| Postings we cannot date | 166,211 · 56.3% |
| Member-contributed sightings held across 229 listings | 282 |
| Sightings promoted into the posting record | 107,702 |
166,211 of 295,482 postings were already live when we first saw them, so we know our first sighting date and not the employer’s posting date. These are recorded as left-censored and excluded from every duration figure.

The record is not evenly spread across the platforms we watch. It is also why so much of it is undated: the Workday adapter never parses the posted date the board displays, because that field is relative text rather than a date, so every posting from it is recorded as left-censored by design.
What we hold a posted date for
| Date reported by the employer's system | 122,218 |
|---|---|
| No posted date available | 166,211 |
| System serves a date that is not a posting date | 2,200 |
| Collected by a halted backfill — excluded from findings | 4,853 |
Dates taken from Workday's detail endpoint by the one-time backfill of schema/080, which was halted on 403 responses and is unresolved with the vendor. Counted among postings because the postings are real; excluded from every duration figure and from every published finding.
How to cite us
Cite the report by its number and the version printed on it, and the methodology version it names. A report’s URL never changes, and previous methodology versions stay reachable, so a figure quoted from one of these can always be checked against the rules that produced it.
