Compare states

Records come from this directory's state data, the same records used by the state pages and the Compare page. This map does not re-verify them; each record's last-verified month is shown with it. Dotted categories come from quoted note text in each record; if that text changes, the state falls back to its recorded value. Map: Blank US Map (states only), Wikimedia Commons, public domain.
