Proportional representation given in three figures? (5,10)
I believe the answer is:
vital statistics
'figures?' is the definition.
(I have seen 'Important figures' mean 'vital statistics' so perhaps 'figures' could also mean 'vital statistics')
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for vital statistics that I've seen before include "that are expanded by a corporation" , "Quantitative data" , "Important figures" , "Miss World will have supplied?" .)
