Kane, the author of a 2010 Kauffman paper on the subject, then combed through the data to make another crucial point. Some of the job loss in existing firms is due to ―Deaths,‖ ., firms closing down. This ―Death‖ toll is especially high for younger firms, as many startups close within a few years of founding. Therefore, it is important that a fair number of the ―Survivor‖ startups keep on growing to help offset the losses—and, as Kane notes, ―Among Survivors, so-called gazelle firms [the kind that grow quickly to large size] are certainly more important still.‖ .
