Hi Heidi,
In addition to Brett's suggestion, you might look at two working papers I wrote for SBA and a third paper of mine in ORM. In these papers I make extensive use of the Census Bureau's Business Information Tracking Series (BITS) file (a cousin of the Business County Patterns database).
1. The two working papers may address your immediate question.
The more recent paper, New Business Clustering in U.S. Counties, 1990-2006, is available at:
http://www.sba.gov/advocacy/849/7629. Among other things, this paper maps entrepreneurial activity in the continental US across several industrial sectors. The second working paper, Rural and Urban Establishment Births and Deaths Using the U.S. Census Bureau's Business Information Tracking Series, is available at
http://archive.sba.gov/advo/research/rs316tot.pdf. This paper includes county rankings by various industry sectors.
2. The third paper addresses, in part, one method to identify entrepreneurial hotspots.
Underlying your question is the issue of how best to compare communities based on their entrepreneurial activity. In my ORM paper, "Spatial Dependence in Entrepreneurship Research: Challenges and Methods," I summarize a spatial data analysis / GIS method for mapping entrepreneurial hotspots. As part of this discussion, I touch on some techniques for adjusting various rate calculations to mitigate the problem of exaggerated estimates in sparsely populated locations (i.e., the small denominator problem). If you have raw ENT data to analyze, you may find this paper useful.
Finally, if you are looking for a specific analysis, let me know.
Best,
Larry

Subject: Entrepreneurial Ecosystems in the United States
I'm looking for valid sources that rank entrepreneurial ecosystems in the United States (cities, states, regions of the country). I have reviewed the U.S. GEM report and the Kauffman Index of Entrepreneurial Activity but am looking for different sources.
Any help would be appreciated.
