I live in a suburban area in the UK (Wales) and we know almost all of our neighbours. We all chat outside regularily when coming home from work or shopping. We take it in turns to look after each others pets when going on holiday. When we go away I have a choice of asking 4 different people to look after my animals and that includes letting my chickens out each morning and locking them up at nght which is an inconvenience but they still do it.
I cook meals for the old folk occassionally. We socialise and attend birthdays, weddings and funerals of each other.
The age range is varied from older retired couples to families with young children.
I think having children helps as they tend to make friends easily and call for each other to play and therefore the parents make friends. However, we knew everyone very well in our road prior to having children.
OP - perhaps you are just unlucky and have ignorant neighbours with no manners
