U.S. entrepreneurship rates climbed to the highest level in more than a decade according to the 2012 Global Entrepreneurship Monitor (GEM) U.S. Report issued today by Babson College and Baruch College. In 2012, the average Total Early-Stage Entrepreneurial Activity rate (TEA) increased to nearly 13 percent, an all-time high since GEM first began tracking entrepreneurship rates in 1999.

“Despite a sluggish economy, 2012 was marked by U.S. entrepreneurs reporting greater optimism and confidence in their abilities to start new businesses,” commented the GEM Report’s lead author, Donna J. Kelley, Associate Professor of Entrepreneurship at Babson College. “In fact, nearly 13 percent of the U.S. adult population was engaged in entrepreneurship with the vast majority starting businesses to pursue an opportunity rather than out of necessity. On the downside, Americans closing businesses were twice as likely as those in other innovation-driven economies to cite difficulties financing their ventures.”
