Methodology

"Collected" means the date OmniLegislation's pipeline processed each record, not the date it was originally filed or published. Counts are deduplicated processed records from OmniLegislation's own pipeline, and item descriptions come from the pipeline's own summaries of each record. Baselines are trailing 30 day daily averages for the same kind of day, weekdays against weekdays, excluding known bulk-load days; highest single-day counts are measured since tracking began on April 5, 2026, and include load days, which are labelled. Bill actions cover tracked bills only. This report covers October 14, 2026. Bill records originate from LegiScan; court opinions from CourtListener, a Free Law Project service; federal regulations from the Federal Register.
