District, locality (4)
I believe the answer is:
area
I believe this is a double definition.
'district' is the first definition.
(a district is a geographical area)
'locality' is the second definition.
(I've seen this before)
(Other definitions for area that I've seen before include "Region; extent of a surface" , "Locality" , "Extent of a two-dimensional surface" , "Territory" , "Space for a specific purpose, say picnic" .)
