Kids are allowed a fair amount of freedom in Canada and Europe, where I still see a lot of kids around malls, or parks, playing basketball in courts (which still happens in NYC), or wooded areas. Sure, more are on their phones etc. But it’s really not that different from the 90s IMO, in many locations.
The biggest change is there aren’t so many clusters of “neighbourhood kids” as there used to be, as people are having fewer children later in life... unless you deliberately seek out a unicorn neighbourhood with similar aged kids. Playgroups and play dates need to be actively organized by parents due to distances between houses.
(I raise two children, and the 10 year old is free to ride his bike and wander, so long as he keeps a phone on for location - he’s taken plenty of bike camps to learn to be responsible).
