APPLE CHIP TIDBIT: How empty is Australia?

Yestereday, while sitting shivering on our very uneven couch on a chilly winter morning here in the southern hemisphere, I was reading a few pages of Bill Bryson's rather witty and clever travel book about Australia, " In a Sunburned Country" and was drawn to a statistic I found rather shocking.  In Australia the average population density is 6 people per square mile! In a country the size of the United States! In the U.S there are over one hundred people per square mile on average. However, Bryson mentions that 6 is skewed wildly due to the fact that over 85 percent of the populations lives in metropolitan areas along the Pacific and Indian Ocean coasts. The reality is that in most of Australia, the density of the population is less than one person per square mile. Taste that salty yet fortified apple chip goodness!
