Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-5a35c52c227e53e3 quantitative

taxi refusal of passengers fell 8.9% and the female population participating in night activities rose 11%

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Seoul's own evaluation page lists both as additional effects of the night bus, alongside the 80.15-versus-74.3 satisfaction scores from a 500-passenger survey.
Caveat: The city government's own figures. No method or control group is stated for either secondary effect, and no independent evaluation of the service has been published.

Known limits of this passport

Publisher names and source languages have not yet been classified; domains are recorded without guessing.
Existing source notes are descriptive locators, not page- or paragraph-exact citations.
A missing archive, publication date or content hash is shown as null rather than inferred.
The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
