Place never represented in measure of popularity? (10)
I believe the answer is:
prevalence
'measure of popularity?' is the definition.
'place never represented' is the wordplay.
'represented' is an anagram indicator.
'place'+'never'='placenever'
'placenever' anagrammed gives 'PREVALENCE'.
'in' acts as a link.
(Other definitions for prevalence that I've seen before include "Superiority" , "Widespread availability" .)
