My grandparents as children lived in farming/ranching communities where all the rest of their family lived. But then along came WWII and after the war many went to college on GI Bills and subsequently ended up living far apart from each other. Their children ended up living in a number of different states. I have eight brothers and sisters and we all live in different states scattered all across the USA from east to west and north to south. It has been decades since we were last all together in the same location. I already assume that my children will settle down somewhere far removed from where they were raised. Heck, I plan on moving away from where I raised them when I retire. I just can't see how it could ever go back to families living in the same town. It seems so unrealistic and infeasible.
