Path of Democracy has commissioned the Public Opinion Programme (POP) at the University of Hong Kong to conduct the Survey on the Centrists in Hong Kong and Political Orientation of Hong Kong People. The target population of this survey was Hong Kong residents aged 18 or above who spoke Cantonese. Telephone interviews were conducted during the period of 12 to 17 October 2015. A total of 1,010 eligible Hong Kong residents were successfully interviewed. The overall response rate of this survey was 65.3%, and the standard sampling error for percentages based on this sample was less than 1.6 percentage points. In other words, the sampling error for all percentages using the total sample was less than plus/minus 3.1 percentage points at 95% confidence level.
