City datasets are fetched live from OpenDataPhilly (phl.carto.com) and cached briefly. Dossiers re-pull automatically — on view once they're a few weeks old, plus a nightly rolling sweep — and citywide benchmarks recompute weekly; the masthead date is when this page's records were last pulled. AI-written passages are generated from these records only and rejected if they state a number the record doesn't hold.
