[DiogenesKynikos]

Switzerland is small but mountainous.

And just for reference:

  * Delaware: 200 people / km^2
  * Switzerland: 230 people / km^2
  * Massachusetts: 350 people / km^2
  * New Jersey: 490 people / km^2

So you can think of Switzerland as Delaware, but landlocked and full of 4,000-meter peaks.
