The Oxford Internet Institute recently highlighted a sharp rise in its Online Labour Index, which “measures the utilization of online labor across countries and occupations by tracking the number of projects and tasks in real time.”
The “normalized” index is based on the number of new projects posted daily to six of the largest English-language labor platforms, reportedly accounting for at least 60% of all traffic to English-language online labour platforms. According to the index methodology overview, these platforms represent a “range of different market mechanisms and contracting styles, from online piecework to hourly freelancing.” Details of the methodology can be found here.
