Jobsearch.ing started from the benchmark figures repeated in existing coverage rather than from a literature search, then worked backward toward the documents they came from.
Each figure was read from its original publication. Where a source was a PDF, the text was extracted and the relevant table read directly rather than relying on a summary, a search snippet, or another page’s description. The specific table or section behind every figure is recorded against its source below.
For every source the numerator, denominator, population, geography, time period and stated limits were recorded, along with what the source does not establish. Figures from different measurement types were never averaged, and where sources appeared to disagree we checked whether the disagreement was definitional before treating it as empirical. In every case examined here, it was.
Interval calculations use the Wilson score method at 95% confidence and are labelled as Jobsearch.ing calculations wherever they appear.
This is not a systematic review. No fixed set of databases was searched against pre-registered criteria, and no claim is made to have found every relevant study. It is a source-tracing exercise on the figures that circulate. The publication’s general standards are on the methodology page, and how corrections are handled is set out in the editorial policy.
