Kauffman Index for Entrepreneurial Activity - National Report 1996-2005
According to the Kauffman Foundations national assessment on entrepreneurial activity, immigrants far outpaced native-born Americans in entrepreneurial activity last year while African Americans were the only major ethnic or racial group to experience a year-to-year increase in the rate of entrepreneurship. A state-by-state breakdown of entrepreneurial activity shows Vermont, Colorado, Montana, Wyoming and Idaho as the states with the highest rates of entrepreneurial activity.
