Although it stages a World Youth Championships in odd-numbered years, the IAAF does not maintain official World Youth Records. These are the best known statistically-acceptable performances by athletes who remain no older than 17 in the year in which the mark is set, as ratified by the T&FN Records Committee. Implements are Youth, unless noted otherwise.
Symbols: (A) = altitude-aided mark—over 1000m of altitude (in affected events only); i = made indoors; p = mark still pending ratification
