World Junior Records are those officially ratified by World Athletics (WA). Junior Records are restricted to athletes who do not turn 20 at any time during the calendar year in which the mark is made.
Symbols: + = event not officially recognized by WA; (A) = altitude-aided mark—over 1000m of altitude (in affected events only); i = made indoors; p = mark still pending ratification
