According to VoxEU, the "gig economy" is bigger than we thought,
Our research concludes that 20-30% of the working age population have spent time as independent workers. Extrapolating this to the US and 15 core EU countries, that’s as many as 162 million people, with up to 94 million in the 15 core EU countries alone. Government statistics show roughly half that headcount, putting the independent workforce at a mere 11% of the working age population in the US and 14% in the EU-15. The difference primarily comes from the fact that more than half of this non-traditional workforce is engaged in independent work part of the time, and also that, in recent years, the gig economy has indeed grown, but still represents only 15%, or about 24 million, of the independent workers in our study. About 9 million out of that 24 are exclusively using digital platforms for their independent work – a little less than 40% – while more than 60% are combining both digital and non-digital means to perform their work.
