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.
