Like about 60% of the world's population (5)
I believe the answer is:
asian
'like about 60% of the world's 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 "from some eastern locale?" , "Relating to one continent" , "Eastern national" , "From Bangladesh, say" , "From large continent" .)
