Daniel Pink, author of Free Agent Nation says a conservative estimate is about 33 million. The government’s statistical apparatus can’t tell us exactly how many Americans have declared free agency. (No surprise really. A century after the United States ceased being a predominantly agricultural economy, federal bean counters still divide work into two categories: “farm” and “non-farm.”) Today’s workforce includes about 16 million Soloists, about 3.5 million Temps, and about 13.5 million Microbusinesses. Some studies have estimated that free agents account for one-third of the workforce – or roughly 42 million people. In all, 30 million represents a rather safe guess.
