Famine
My hometown is 5 minutes from the 3rd largest shopping centre in the North of England, and 10 minutes from the centre of the 4th largest city in Britain. It's also 5 minutes from the Peak District National Park.
I choose both.
Like Val Kilmer in the only Batman film that rocked my boat ...
There is very little country left in the first place so a very small percentage lives on it - the question is mostly city or village, but even in a village a city is always very nearby. Nevertheless, there's still some country left, in the North, East and South. But I couldn't live there, I need something like where I'm now, which is about halfway.
I live in the fastest growing city in the Netherlands, grown from 0 to 160.000 in 25 years and looking to reach 230.000 in 2010. It's a city that mostly intends to provide a decent place to live for those mostly young families that can no longer afford to live in Amsterdam, which has risen this year to the 24th most expensive city in the world (from something like 48th last year). The city is divided into four major sections, and the section I live in is not the real center, but a little more on the outside. I guess you could call it suburbia. The area I live in is very green and nice and I can put on my rollerblades or take my bike to enjoy a good bit of nature, but I can walk to the train station in 5 minutes and there's a fairly decent city center and a big section next to it that combines all sorts of shops that have to do with homes (e.g. furniture, carpets, paints, plants, electronics, and so on).
However, finding a place in the Netherlands where you can walk for more than 10 minutes without meeting anyone is pretty hard. This is something we greatly envy in other countries, which is why many Dutch tend to go on holiday a lot and often far away, and emigration is a big thing too - countries like Canada are popular spots for farmers for example, who don't really have a future over here.
