That sounds like the village in which I spent my teens. Population of ~500, and for <18s there was myself, my sibling, and there was a "new" housing estate had a handful of kids around 5.
We didn't have nice paths, there was a (former) main road going through the middle of the village. As far as local infrastructure, there was the pub, a car mechanic, and every few years a corner shop would open up and last about 2-3 years before shutting down again.
If you needed groceries you went to the larger village (population ~1000) which was about a 40 minute walk along the main road (which only got dedicated pavements after I had moved out), or a 5 minute drive. For amenities that larger village had 2 bars, 2 churches, a takeaway, a supermarket, a primary school and a garden centre.
If you needed anything more than groceries, you needed to go to one of the nearby towns which were ~20-30 minutes by car and (according to google maps) ~2 hours walk.
