Social issues in China are wide-ranging, and are a combined result of Chinese economic reforms set in place in the late 1970s, the nation's political and cultural history, and an immense population. Due to the significant number of social problems that have existed throughout the country, China's government has faced difficulty in trying to remedy the issues. Many of these issues are exposed by the Chinese media, while subjects that may contain politically sensitive issues may be censored. Some academics hold that China's fragile social balance, combined with a bubble economy makes China a very unstable country, while others argue China's societal trends have created a balance to sustain itself.

He said land seizures and the widening wealth gap were the two top factors: Since the beginning of Deng Xiaoping's reforms in 1979, the disparity between the urban and rural populations has risen from 2.56:1 in 1978 to 3.33:1 in 2009. Urban income in 1978 was 343 yuan whilst rural income stood at 134 yuan; in 2009, the corresponding figures were 17,175 yuan and 5,153 yuan respectively. Despite the overall increase in urban income, unemployment, unpaid wages, and police misconduct are sources of grievance. Corruption is a very big issue in china. Regional imbalances Rural-urban disparity and the wealth gap Since the economic reforms in China began, income inequality has increased significantly. The Gini Coefficient, an income distribution gauge, has worsened from 0.3 back in 1986 to 0.42 in 2011. Poverty researchers recognize anything above 0.4 as potentially socially destabilizing.
