Yup. Cities often have lots of impressive public green spaces so I expect this a massive underestimate.

It may be worse for a rural kid. All that countryside that surrounds you is private farmland. Of course, now and again, you trespass and earn stories of being chased off by dogs and puce-faced-shotgun-wielding arses but it's not your daily hang-out.

Truly public land (not just a public pathway) will be concentrated in nature-reserves and odds are it will be out of reach except for special adventures.

The village-kid hang-out is typically "The Village Rec" (recreation ground) but if you live in something less than a village, i.e. random splats of houses between villages, you end up living half your life at a bus stop waiting for the mercurial 2-hourly bus service before you can even see another human face.
