When I was a child my parents used to sit in front of our house and drink tea. The neighbors would do the same and all children would play together. But thanks to longer working hours and the fear induced by the 24/7 news cycle no one dares sit outside anymore. My nieces don't know their neighbors.
When I was a teenager there was a specific square where one would go after school (or during if you skipped class that day). As far as I know my nieces don't have such a tradition.
Less clear example: in my country of origin those living in apartments used to have monthly meetings to discuss any issues they had about the building. People used to complain going to those, but at least you'd get an overview of who is who. I believe these meetings are gone, replaced by email. No one complains about them anymore but, at the same time, no one knows who their apartment neighbors are.
My children are still a bit too young, but there are lots of kids that play in my neighborhood in DFW. The city park at the end of my street has families playing, people out walking their dogs, fishing in the ponds. People play sports at the fields in the park. People hang out on their front patios when it's not 100F outside, have trunk or treats at the park, etc.
The apartments I've lived in the past several years had get together events from time to time. I also met a lot of neighbors going to the gym or hanging out around the pool or playing billiards in the clubhouse.
None of this seems radically rare from my experiences in Houston and DFW.
Average amount of time spent working has trended downwards for nearly every income group for every decade except at best the last decade where it's been stabilizing around ~33 to 36 hours a week or 1700 - 1800 hours a year. I'm not specifying a country because I don't have to, the only country that has actually trended upwards in working hours is China.
