I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for ghost town that I've seen before include "where there's no-one around" , "deserted place" , "Deserted urban area" , "There's nobody in it" , "Old settlement, now deserted" .)

I've seen this clue in The Guardian.
