Rural life and city life can often intertwine, so be sure to mention that unlike the US, it's not one or the other.
Many large resort villages have cow pastures, where the non-tourism based locals farm. In the mountains animals have very high quality of life, and graze in large free pastures with fresh grass and flowers. The farmers there work very hard, but enjoy a simple and healthy lifestyle in one of the most beautiful places in the world.
In the Valais (Wallis if speaking in German), where most wine grows, there are vineyards on almost every slope of the valley. Most vineyard farmers live in the cities or small towns (see below) and commute to work.
Generally, rural life is usually mixed in with all but the largest urban areas, and rural workers often either live a simple but healthy lifestyle with lots of hard work, or live an urban life, still with lots of hard work.
Almost all cities above 1000 inhabitants in Switzerland are connected by railways, which are almost always clean and on time. For this reason, commuting is very commonplace for almost everybody, but it's never a stressful experience. Many Swiss, myself included, are able to sleep easily on the train to work (an extra hour for me!), and finish up any tasks on the train back home.
Cities are small, Bern for example being only 150,000 persons or so, but there are many smaller cities surrounding them that merge together. However the Swiss don't call these areas suburbs, but simply different places.
Cities are very clean, and street traffic is low considering the ammount of action going on. Trams and electric busses stop at almost every street corner, and people often walk. Things are never too crowded, but the locals are always out enjoying the shops.
Switzerland as a whole is a very clean, safe, and simple society, built up of people who work hard to keep it that way. There are not the dividers between social classes like there are in the US. I've never had a person ask me what neighborhood I come from, or how much I make. I invite the janitor who works at the firm I'm with to my parties, and he's treated as welcome as my boss. Most people in Switzerland are out to work together, and there are very fine lines between what is rural and what is urban, what is upper and lower class.
Putting it into a single word, I like to think that all of Switzerland is "Rurban".
Or should that be "Urral"?
