On a global scale, we calculate that the adaptation of currently demonstrated automation technologies could affect 49 percent of working hours in the global economy. This potential corresponds to the equivalent of 1.1 billion workers and $11.9 trillion in wages. Among countries, the potential ranges between 40 and 55 percent, with just four countries—China, India, Japan, and the United States—accounting for just over half the total wages and workers. The potential could also be large in Europe: according to our analysis, the equivalent of 54 million full-time workers and more than $1.9 trillion in wages are associated with technically automatable activities in the continent’s five largest economies alone—France, Germany, Italy, Spain, and the United Kingdom.
