Each row is a notice as published by the agency. For state lists, the number affected counts only that state's residents; HHS lists the total reported. SEC rows are Form 8-K Item 1.05 filings, which usually don't give a count. A notice does not mean a settlement exists, and a settlement may cover a different incident than a given notice.
