Eagle County's economy has transformed over time from a combination of mining and agriculture in its early history to a combination of destination tourism, construction and second homes today. While tourism will continue to be a primary economic driver, some speculate that the next shift in the economy will be towards the knowledge and creative economy with many jobs and activities related to technology, research, design, and entrepreneurship.
