Rally with shocking population base (11)
I believe the answer is:
demographic
'base' is the definition.
Although both the answer and definition are adjectives, I can't understand how they can define each other.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for demographic that I've seen before include "(Statistic) relating to the study of human populations" , "Relating to the structure of populations" , "Relating to the statistical study of populations" , "Relating to the make-up of human populations" , "one section of population" .)
