HKU POP enhances its survey standards and announces its policy address survey plan Back


Press Release on October 9, 2017

Concurring with the 20th Anniversary of the HKSAR, starting from July this year, the Public Opinion Programme (POP) at The University of Hong Kong has been reviewing and revising its many survey designs. After three months of testing, and enchoing the beginning of a new policy year, POP formally implements the following changes starting October this year:

(1) Other than using landline samples, POP introduces mobile numbers in all its regular surveys in the ratio of 4:1 to become mixed mode samples.

(2) For instant surveys, on top of the mixed mode random samples described, an equal number of “panel samples” would be added, these are pre-selected random samples who have agreed to be re-interviewed on the survey day.

(3) “Effective response rate” will be used to describe all samples. As for the weighting method, a two-step protocol will be used. First, all sub-samples will be rim-weighted according to figures obtained from the Census and Statistics Department regarding the gender, age, educational attainment and economic activity status distribution of Hong Kong population. After that, all sub-samples will be rim-weighted according to the basic Public Sentiment Index (PSI) figures collected in the landline sample. This weighting method has proven to be feasible after three months of testing, but POP will continue to review and enhance it, and keep the public informed.

Since 1992, POP has been conducting Policy Address instant surveys every year. In 2008, we split it into two. In our first survey, we measure people’s overall appraisal of the Policy Address, their rating of the Policy Address, their change in confidence towards Hong Kong’s future, and CE’s popularity. In our second survey, we focus on people’s reactions towards different government proposals, their satisfaction with CE’s policy direction, and other relevant issues. Tomorrow (October 10), we will release our survey on people “expectations on the policy address” as scheduled. On October 11, we will engage more than 100 telephone interviewers to survey people’s instant reaction to the address. The preliminary results will be released via our “POP Site” ( for the public consumption, at around 10 pm, including: “How satisfied are you with Chief Executive Carrie Lam’s Policy Address delivered today?” and “Please use a scale of 0-100 to rate your degree of satisfaction of the policy address delivered by Chief Executive Carrie Lam today, with 0 indicating very dissatisfied, 100 indicating very satisfied and 50 indicating half-half.” Detailed results including those of other questions will be released at noon the following day (October 12).
