Among larger states (annual $20 billion plus), Colorado ranks third for growth in health expenditures; with 7.7% average annual growth from 1991 - 2004 (compare spending map below). Denver is also central in a group of states with above average growth in health spending (green & blue pins). 

Colorado is one of the most rewarding markets for health professionals (compare areas). Why? One reason appears to be (i) the high level of medical insurance (at 49.8%), combined with (ii) a greater willingness for Coloradans to pay for health services out of pocket (at 25.4%) according to a 2006 study by the Agency for Healthcare Research and Quality (view the data).
