Housing prices, social security and employment are the top three concerns of Chinese living in big and medium-sized cities, according to an online survey on urban life quality.

The survey, to which 773,325 people in 287 county-level cities responded, covered income and consumption of urban residents.

The survey found housing prices were the biggest worry. Thirty-five percent of respondents said they could not afford housed prices in the cities where they lived, including Beijing, Shanghai, Hangzhou, Suzhou, Ningbo, Dalian, Guangzhou, Zhengzhou, and Wenzhou.

Social security and employment were another two major concerns, according to the survey.

The two-year on-line survey was organized by Beijing International City Development Institute in cooperation with dozens of research institutions and more than 100 experts.
