Freelancers Now Make Up 35% of U.S. Workforce
First off, their sample size (6,000) is pretty small to be generalizing to all Americans.  Second, if 63% of these freelancers (which is pretty loosely defined in their survey) say they are freelancing voluntarily, that means 37% would rather have a normal full-time job.  So 13% of total people in the "workforce" are forced to freelance and are likely underemployed as a result.  That's not exactly indicative of the healthy job market the BLS likes to claim we have.
