Most of New York redevelopment is in less densely populated islands (6)
I believe the answer is:
orkney
'less densely populated islands' is the definition.
'orkney' can be an answer for 'islands' (I've seen this before). I am unsure of the 'less densely populated' bit.
'most of new york redevelopment' is the wordplay.
'most of' means to remove the last letter.
'redevelopment' indicates an anagram.
'new' with its last letter removed is 'ne'.
'ne'+'york'='neyork'
'neyork' anagrammed gives 'ORKNEY'.
'is in' acts as a link.
Can you help me to learn more?
(Other definitions for orkney that I've seen before include "-- Islands are off northern Scotland" , "Islands off north coast of Scotland" , "Scottish location" , "-- Islands (Scots)" , "Isles north of Pentland Firth" .)
