(KANSAS CITY, Mo.), July 7, 2010 – When it comes to U.S. job growth, startup companies aren’t everything. They’re the only thing. It’s well understood that existing companies of all sizes constantly create – and destroy – jobs. Conventional wisdom, then, might suppose that annual net job gain is positive at these companies. A study released today by the Ewing Marion Kauffman Foundation, however, shows that this rarely is the case. In fact, net job growth occurs in the U.S. economy only through startup firms.
The new study, The Importance of Startups in Job Creation and Job Destruction, bases its findings on the Business Dynamics Statistics, a U.S. government dataset compiled by the U.S. Census Bureau. The BDS series tracks the annual number of new businesses (startups and new locations) from 1977 to 2005, and defines startups as firms younger than one year old.
The study reveals that, both on average and for all but seven years between 1977 and 2005, existing firms are net job destroyers, losing 1 million jobs net combined per year. By contrast, in their first year, new firms add an average of 3 million jobs.
Further, the study shows, job growth patterns at both startups and existing firms are pro-cyclical, although existing firms have much more cyclical variance. Most notably, during recessionary years, job creation at startups remains stable, while net job losses at existing firms are highly sensitive to the business cycle.
