Kauffman Foundation: Baltimore city has 4.2 Inc. 500 companies per 100K people

If you aspire to one day own a company that appears on the Inc. magazine 500 list, you need not relocate to Silicon Valley to do so.
In fact, according to a map produced by the nonprofit Kauffman Foundation that “analyzed 30 years’ worth of Inc. 500 lists,” it might be better to head to the Washington, D.C., area, Yahoo reports.

The report:

The nation’s capital has been home to more Inc. 500 companies than any other major metropolitan area. … Innovation is coming from some surprising places. When adjusted for population, Indianapolis ranks 6th in the number of Inc 500 firms, and Buffalo ranks 11th. Other cities you might not suspect: Baltimore (15th), Philadelphia (19th) and Louisville, Kentucky (20th). [more]

The map created by the Kansas City-based Kauffman Foundation that “displays [by county] the location of the fastest-growing privately held companies appearing on the annual Inc. 500 list from 1982 to 2010″ shows just as much.
Baltimore city can claim 4.2 Inc. 500 companies per 100,000 people (of a total population around 620,000), while D.C. is home to 11.3 companies per 100,000 people.
By comparison, Arlington County in Virginia, home to around 216,000, boasts an impressive 50.4 companies per 100,000 people.
