¹ A means altitude over 1000m, a means altitude between 500-999m. The altitude of a venue in metres is listed in brackets after the city name when (a) it's over 200m and (b) the data is available.

² In the wind-assisted list, where there is a time (like 10.17-80) rather than a DOB, the time refers to the athlete's best legal time as a junior (which will be in the main list).

³ the number of performances an athlete has to that point - 2 is their second time in the list, 5 is their fifth, etc.

A junior under IAAF rules celebrates their 20th birthday in the year of competition, ie to be a junior in 1984 an athlete must have been born in 1965 or later; to be a junior in 2003 an athlete must have been born in 1984 or later. 19 yr olds are not always juniors – if born in December 1983, for example, an athlete is not a junior in 2003 despite being aged 19 for almost the entire year.
