I`m doing this piano survey at school and i`m wondering if i could graph a percentage of people who have perfect pitch in AUSTRALIA. . . because i have perfect pitch but i don`t know anyone else who does. Can any of you guys help me? any information would be appreciated.

perfect pitch, by the way, is when you can tell if something`s off key/out of tune, and if you can play things by ear. i would love to hear from you if you have this gift.
