I come from a small town, small enough to yell across and we're perfectly safe leaving our doors unlocked. Home invasions and break ins are unheard of entirely, in the last 30 years at least. Similar behavior in surrounding towns with slightly larger populations.

I lived in a small, ostensibly safe town in Sweden, but people would come in from outside to violate the trust the people had. You need to be good friends with your neighbor so they can confront or report any suspicious outsiders.
