The U.S. death rate is 8.34/1000 (2004)

http://edition.cnn.com/2004/US/12/22/dying.homeless.ap/index.html
"The homeless coalition estimates there are more than 3.5 million 
homeless Americans nationwide. An estimated 3,000 died last year, and 
the homeless coalition expects that figure to rise this year."

3,000/3.5 million = 0.86/1000

The average American is 9.7 times more likely to die than a bum.
