Interpretation
What these aggregates mean
They describe the public records included in this release. They are useful for seeing coverage, missingness, concentration, and reported patterns. They do not establish causation or individual quality.
Counts are computed during the same build that creates the map and record pages. A source update changes the analysis automatically.
