Is that actually true, beyond this anecdote? FWIW, my own suburban neighborhood (a cluster of about 60 townhomes) has enough kids that there's usually a small basketball game going on in the parking lot. And often bikes left scattered around (until dinner time, when the kids pick them up and go home).

In my experience as a parent (my son moved out last year), there were always kids around, but they were scheduled down to the minute in sports, STEM enrichment activities, scouts, or church. And those kids from families that didn't have that kind of budget were glued to TV screens or computer monitors.

We tried to give our son free time to play, but there was nobody around to play with. The kids were there, just not available.

Now that we've moved to a smaller house, with THs instead of SFHs, it appears to be slightly better. More play in the parking lot. But, the kids still seem pretty tightly scheduled (almost all are in sports leagues year-round).

I don't think this is the issue. It's much more a cultural thing, statistically richer countries have lower birthrates. But getting married and having kids is no longer accepted as "just what you do". Less people are getting married, that also may play a role.

I'd also imagine it's different in different areas. Might even map to incomes, or political leanings of different zip codes.

But of all its problems, what's the problem with kids having to ride 1+ miles to their friends?

When I was about 10-11, I was riding 2kms by myself (and then with my younger sister) in the Australian summer holidays down to a tennis camp. Sometimes it ran late and the sun went down, so my parents would come and pick us up in their car...just kidding, they bought me a generator to put on my bike and a reflector and I rode home in the dark.

When we moved again, I had a regular neighbourhood friend and we'd go and play networked computer games and nintendo during school holidays and after school during my teenage years (having two pc's you could network was quite advanced for the 1990's). But putting this into google, his place was 1.4 kms away from my house.

There was a video store 5 to 6 kms by car that had some rental games and videos, but of course we couldn't drive. But it must of been 4-5 kms by taking a shortcut through a nature reserve with our mountain bikes. And that's what we did. After a year or two, another store opened up a few kms in the other direction and we went there as well.

Even back then, video games were a huge part of my life...we were nerds in the absolute sense, but so were the mountain bikes and the exploring. Maybe we were lucky backing on to some nature reserves, but even in the staid morass of suburbia, are there too many places with nothing in a 10km radius? And even if the answer is yes, even that I'm a bit skeptical of. The nature reserve attracted us because it was a place without adults and it was a little bit dangerous, not because it was set up with activities or playgrounds.

In my mind, the distance wasn't a barrier to playtime. The fact that our parents would let us out to explore, and we subsequently went within about a 10km radius of our homes unsupervised on our bikes and without cell phones WAS the playtime.

The changing variable isn't the distances: its the supervisory culture and the fact that everything is now streamed conveniently into our homes on demand, and the fact that many of these products are now specifically engineered to try to turn people into screen viewing zombies.

That doesn't necessarily mean much. Moving from urban areas to suburban ones already greatly reduces density and access to services and the sort of institutions we are talking about.

To give some sense of proportion, the average American suburb has[1] a density of about 2.7k people per square mile. That's about 2 1/2 times less dense than a Western European suburb (6.2k), and about eight times less dense than a Western European core urban area (18.8k).

American suburbia is extremely sparsely populated and fundamentally unfit to provide the cultural institutions that modern, small families and communities require. Calls for larger families is simply unrealistic, because the opportunities that each kid in a large family on a single income in a developed knowledge economy gets are abysmal. In our modern world, quality trumps quantity so to speak.

I often wonder how much of my solitary/introverted personality is the result of my environment.
