'citizens' is the definition.
The definition and answer can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?

'unsociable types bored by fellow' is the wordplay.
'unsociable types' becomes 'loners' (I've seen this before).
'bored by' means one lot of letters goes inside another (to bore something can mean to drill into it).
'fellow' becomes 'don' (both can mean an academic).
'loners' going around 'don' is 'LONDONERS'.
