Median incomes in Colorado have fallen 8.4% from 1999 to 2005, after adjusting for inflation. This is more than the national average drop of 6%.
A different data set, free of issues some have criticized in the Detroit Free Press data set, is even worse for Colorado. It shows a 10.6% decline in median income in the state in real dollars since 1999.States in the Northeast, California, Hawaii, and the Rocky Mountain States and Great Plains North of Colorado have done better.
The Northwest, the South, the Southwest, and much of the Midwest has done worse.
