Like about 60% of the world population (5)
I believe the answer is:
asian
'like about 60% of the world population' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for asian that I've seen before include "One from the East" , "Indian or Thai?" , "Of the largest continent" , "florid writing" , "eg Pakistani" .)
