Rural is subjective. My version of rural is miles and miles of open countryside surrounding your house and at least a 30 min drive from the nearest town and at least an hour’s drive from the nearest city, unless it’s a very small one.
I don’t count a place with multiple shops, takeaways and a supermarket a ‘village’ even if it is surrounded by countryside.
I’d count no more than about 700 houses, and nothing more than a church/ pub/ primary school as a village. For me, anything much over that and I’d consider it a small town.
However, the above, I’d still count as ‘rural’ I’d consider it a ‘rural village’ which is what I live in. There’s not many of us here, the village itself is only a mile long and consists of a primary school and a little pub. That’s it. The nearest shop is in the next village which is a 10 min car drive away. So yes, we’re certainly not isolated but we are rural IMO.
I know people from London who consider themselves rural and ‘in the countryside’ and live in a ‘village’ they’re just not and don’t. A village has to have less than 2,500 inhabitants and no London zone/ borough has that.
But I do think people get ‘rural’ and ‘isolated’ mixed up. You can be slap bang in the middle of countryside and have 50 neighbouring houses and be ‘rural,’ you just wouldn’t be isolated
