Coverage Rate
Coverage rate is the share of a defined target universe that a database can represent at a usable level of detail.
Definition
Definition Coverage rate measures how much of a defined market a dataset captures. It’s not a vanity number—it’s meaningful only when the “universe” is defined and the depth threshold is clear (e.g., entity-only coverage vs entity + verified contacts + roles). Context In family office data, coverage can look high on paper if the dataset lists many names, but it may be low in practice if records are incomplete, stale, or duplicate. Coverage rate should therefore be interpreted alongside verification status, record completeness, and entity resolution quality. A credible coverage rate is one that can be explained and repeated. Why It Matters Coverage rate impacts whether a database can be trusted for systematic market mapping. Fundraising teams need predictable coverage to build target lists, assign ownership, and avoid blind spots. Key Takeaways Coverage rate depends on a clearly defined universe Record depth matters as much as record count Coverage must be paired with accuracy and completeness Strong coverage supports systematic fundraising execution
