China’s Gini coefficient, a measure of income inequality, is higher than that of the US and among the highest in the world, Bloomberg reported, citing a University of Michigan study that will be published online this week in the Proceedings of the National Academy of Sciences. Using data from surveys conducted by universities in China from 2010 through 2012, researchers found that the Gini coefficient for family income in China was around 0.55 compared with 0.45 in the US. A coefficient of 0.5 or higher indicates a severe gap between rich and poor.
