The Business Dynamics Statistics provide annual statistics on establishments, firms, and job creation and job destruction from 1976 to 2012 by firm age and size. These statistics are crucial to understanding current and historical U.S. entrepreneurial activity. The statistics come from a collaboration between the Census Bureau's Center for Economic Studies, the Small Business Administration, and the Ewing Marion Kauffman Foundation, an American nonprofit organization that focuses on entrepreneurship.
