Methodology

Data is sourced from CFPB's terms survey, historical web archives, and live extraction for the current quarter, merged via a documented source-priority hierarchy. Every field's source is tracked, and where no source has ever reported rewards data for a card, a disclosed, conservative category-typical estimate is used rather than leaving an unexplained gap — flagged explicitly, never blended silently with observed data.

The dataset is delivered as a processed, analysis-ready table (CSV or JSON) — no further cleaning required.
