About this derivation
These lists are derived from the marks in our database — including the complete legal all-time lists imported from alltime-athletics.com — grouped by the nation the athlete was representing at each mark. They are not official national records: federations ratify national records under their own eligibility rules, and some marks here may not qualify.
