Figures to be accurate in one area (8)
I believe the answer is:
district
'area' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for district that I've seen before include "Area of a town or city" , "Area (of a town/city)" , "Territorial division" , "Area, region" , "Locality" .)
