Abstract: The Kauffman Index of Entrepreneurial Activity is a leading indicator of new business creation in the United States. Capturing new business owners in their first month of significant business activity, this measure provides the earliest documentation of new business development across the country. The percentage of the adult, non-business-owner population that starts a business each month is measured using data from the Current Population Survey (CPS). In addition to this overall rate of entrepreneurial activity, separate estimates for specific demographic groups, states, and select metropolitan statistical areas (MSAs) are presented. The Index provides the only national measure of business creation by specific demographic groups. This index measures flows into business ownership rather than the number of existing business owners at a specific point in time as collected by the American Community Survey (ACS). The 2007 Survey of Business Owners (SBO), the Business Employer Dynamics (BED) or the Statistics of U.S. Businesses (SUSB) all have firm level information while Kauffman Index meaures individual business owners.
