Dan Levine, Research Analyst at TechCrunch, has just launched TechCrunch Trends. The idea is to provide analysis of the CrunchBase database of startup activity, and R is the tool used to conduct the analysis.
The first installment investigates hotspots of activity in the United States where startup activity is concentrated. It turns out that the greatest concentration of startups over all time is located in a zip code just around the corner from me: Potrero Hill in San Francisco, where a total of 153 start-ups have been founded. In fact, of the top 15 zip-codes for start-up foundation, 12 are in Silicon Valley, which shows up clearly in the map below.
The top 15 is rounded out by Seattle and New York (with two zip-codes).
