A Peking University report says China's Gini coefficient has increased from 0.3 in the early 1980s to 0.45 last year, but it is down from 0.49 in 2012. The Report also said one-third of China’s wealth is owned by the top 1% of households, while the bottom 25% account for only 1% of the wealth. The China Family Panel Studies, launched in 2010, covers 14,960 households in 160 regions of 25 provinces nationwide, and focuses on the “well-being of the Chinese population.”
