Limitations
- The reporting organization may differ from every affected entity.
- Coverage is bounded to the reviewed 2024 through 2026 annual reports rather than the full series beginning in 2007.
- Affected-resident totals may change as reporting organizations update counts.
- The source can publish placeholder and duplicate-marker rows without independent notification facts; those rows are counted and excluded.
- Consumer notification letters are excluded.
Correction process
Check the current official annual reports and report index; do not retrieve or reproduce consumer notification letters.
