There does seem to be a breakdown in community relationships compared to a few generations ago. More isolated households, more single person homes, fewer households with grandparents living close, more short term lettings, fewer community activities that bring people together, and maybe different reactions to technology, crime, drugs and newcomers.

Then again I think some of the accounts of open door communities in the past were a bit rose tinted.

I just saw this story from the BBC about a woman (maybe murdered) who lay in her flat for 2 years before anyone investigated. Not much neighbourly concern there when she disappeared:

Very sad.
