Changes

Examine health of entrepreneurship ecosystem within an MSA or CMSA and how it is affected by the proximity of venture-backed companies to one another (measured by minimum circle area between firms within the MSA). The goal is to see whether MSA's with closer or further proximity between companies see greater growth in successive years. In order to be considered "living," the companies must have not undergone IPO's, liquidations, or acquisitions and must have received venture funding within the last 5 years. If these requirements are not met, they are dropped from the data.
