New figures show average personal income in the state grew 5.1%last year, Colorado's fastest rate in five years.
The US Bureau of Economic Analysis also says Colorado's growth rate was one percentage point better than the national average.
The latest statistics indicate Colorado's per capita income stood at $37,946 in 2005, with pay increasing in the professional and technical fields, construction and health care.
A collapse in the technology industry had kept Colorado near the bottom of the national income growth rankings since 2000.
Nationwide, per capita income growth was strongest last year in the Rocky Mountains and the Southwest, and weakest in the Great Lakes and states hit by Hurricane Katrina.
