It’s a new day in the neighbourhood all across the Western world. More than 30 per cent of Canadians now say they feel disconnected from their neighbours, while half of Americans admit they don’t know the names of theirs. An Australian sociologist investigating community responses in the wake of the 2011 floods in Queensland found relations in “a precarious balance”; neighbours were hesitant to intrude even in emergencies—leading the scholar to conclude that “we are less likely than ever to know” our neighbours. Quite right, too: A recent poll of 2,000 Britons found a third declaring they couldn’t pick their near neighbours out of a police lineup.
