Using large sample data，this paper comprehensively analyzes the amount of reading of Chinese people，which demonstrates that the amount of reading is closely correlated with family leisure time and individual’s social status. People who have higher education level，higher social class，and better social economic situation usually have larger amount of reading. Furthermore，under the background of social development，most people prefer books relating to health-care，life and art. Therefore，the disparity of reading habits among different social classes determines the tendency of reading in the whole society.
