Data quality

Promoting normalized data requires passing checks for structure, periods and dates, label and entity-name usefulness, the global duplicate rate, and editorial presentation.

This table evaluates sources registered for normalization in VerDat, including those without a quality report yet. Sources queried directly through official APIs do not pass through these promotion gates and are not listed here; their quality depends on the provider’s published data.

2 sources have a newer refresh that failed the checks; the last approved layer stays published.
