Special Announcements
1. From July 2017, apart from sampling landline numbers to conduct opinion surveys, the Public Opinion Programme (POP) of The University of Hong Kong has also added mobile numbers to the sampling frame. After three months of testing, in October 2017, POP formalized the use of mixed samples as its standard for regular opinion surveys. The figures released today by POP have already incorporated landline and mobile samples, while “effective response rate” is continued to be used to describe the survey’s contact information. As for the weighting method, a two-step protocol is used. First, both the landline and mobile samples have been rim-weighted according to provisional figures obtained from the Census and Statistics Department regarding the gender-age distribution of the Hong Kong population in 2016 year-end, and the educational attainment (highest level attended) distribution as well as economic activity status distribution collected in the 2011 Census. After that, the mobile sample was rim-weighted according to the basic Public Sentiment Index (PSI) figures collected in the landline sample, and then mixed together to produce the final results. This weighting method has proved to be feasible after three months of testing, but POP will continue to review and enhance it, and keep the public informed.
2. To facilitate academic study and rational discussion, POP has already released for public examination some time ago via the “HKU POP SITE” (http://hkupop.pori.hk) the raw data of regular rating surveys of current CE Carrie Lam, former CEs CH Tung, Donald Tsang and CY Leung, along with related demographics of respondents. Please follow normal academic standards when using or citing such data.
Abstract
POP conducted a survey on people’s satisfaction with the disciplinary forces in mid-November 2017 by means of a random telephone survey conducted by real interviewers. The survey shows that the recognition rates of the Fire Services Department, the Police Force, the Independent Commission Against Corruption, the Immigration Department and the Customs and Excise Department are all higher than 95% and those of the Auxiliary Medical Service and the Government Flying Service are higher than 90%, while those of the Civil Aid Service and the Correctional Services Department are higher than 80%. This shows that Hong Kong people are quite familiar with all our disciplinary forces. In terms of relative rankings, the Fire Services Department continues to rank first with a rating of 84.1 marks. The Government Flying Service and the Auxiliary Medical Service rank second and third. The Civil Aid Service, the Customs and Excise Department and the Immigration Department rank fourth to sixth, while the Independent Commission Against Corruption, the Correctional Services Department and the Police Force rank seventh to ninth. Compared with the last survey, the overall rankings of all disciplinary forces have not changed much. In terms of absolute ratings, all nine disciplinary forces get more than 65 marks, seven of which are above 70, which is very good. A point to note is that, the ratings of the Government Flying Service and the Civil Aid Service have reached record high since 2012, while those of the Auxiliary Medical Service and the Independent Commission Against Corruption have reached record high since 2013. The rating of the Police Force is 66.9 marks and continues to be the lowest among the nine disciplinary forces. Its net satisfaction rate is positive 37 percentage points representing a slight increase of 2 percentage points. Meanwhile, the popularity rating of the PLA Hong Kong Garrison stands at 64.1 marks, while its net satisfaction rate stands at positive 44 percentage points, which has significantly increased by 11 percentage points when compared with half a year ago. The maximum sampling error of all percentage figures is +/-4 percentage points, while that of rating figures is below +/-2.5 marks at 95% confidence level, and the sampling error of net values need another calculation. The response rate of the survey is 63%.
As for the Public Sentiment Index (PSI), the latest PSI stands at 122.4, up 13.4 points since mid-November, again reaching a new record high since Carrie Lam took office and back to the level around mid-year 2008. This time both component scores of PSI increase. Specifically, the Government Appraisal (GA) Score that reflects people’s appraisal of society’s governance goes up by 9.0 points to 118.6, and the Society Appraisal (SA) Score that reflects people’s appraisal of the social environment increases by 15.1 points to 114.4.
Points to note:
[1] The address of the “HKU POP SITE” is http://hkupop.pori.hk, journalists can check out the details of the survey there.
[2] The sample size of the survey is 1,011 successful interviews, not 1,011 x 62.8% response rate.
[3] The maximum sampling error of percentages is +/-4 percentage points at 95% confidence level, while the sampling errors of rating figures and net values need another calculation. “95% confidence level” means that if we were to repeat a certain survey 100 times, using the same questions each time but with different random samples, we would expect 95 times getting a figure within the error margins specified. When quoting these figures, journalists can state “sampling error of rating not more than +/-2.5, that of percentages not more than +/-4%, and that of net values not more than +/-6% at 95% confidence level”.
[4] Because of sampling errors in conducting the survey(s) and the rounding procedures in processing the data, the figures cannot be too precise, and the totals may not be completely accurate. Therefore, when quoting percentages of the survey(s), journalists should refrain from reporting decimal places, but when quoting the rating figures, one decimal place can be used.
[5] The data of this survey is collected by means of random telephone interviews conducted by real interviewers, not by any interactive voice system (IVS). If a research organization uses “computerized random telephone survey” to camouflage its IVS operation, it should be considered unprofessional.
I. Disciplinary Forces and the PLA Hong Kong Garrison
Background
Since its establishment in 1991, POP has been conducting different types of opinion studies on social and political issues. Shortly after the handover of Hong Kong in July 1997, POP began our regular surveys on people’s satisfaction with the Hong Kong Police Force and PLA Hong Kong Garrison. In 2012, POP revised the design of this survey series by splitting the survey into two stages. A naming survey of people’s most familiar disciplinary forces in Hong Kong was conducted first, followed by another survey on people’s satisfaction with top 6 most familiar disciplinary forces, as well as the PLA Hong Kong Garrison. In mid-2015, POP expanded the scope of the satisfaction survey to cover all nine disciplinary forces in Hong Kong, plus PLA Hong Kong Garrison, thus doing away with the naming survey while increasing the reference value of the entire survey. In late 2017, the focus of the survey was changed to satisfaction ratings. For the questions that used the 5-point scale, only the two on the satisfaction of the Hong Kong Police Force and the PLA Hong Kong Garrison were kept for the purpose of long term tracking. All findings of these surveys are published regularly at the HKU POP Site.
Latest Figures
POP today releases via the POP Site the latest popularity figures of Hong Kong disciplinary forces and the PLA Hong Kong Garrison. From July 2017, POP enhanced the previous weighting method that has been used for quite a few years. Apart from age, gender and education, economic activity status is now also taken into account when adjusting data. The latest figures released today have been rim-weighted according to provisional figures obtained from the Census and Statistics Department regarding the gender-age distribution of the Hong Kong population in 2016 year-end, the educational attainment (highest level attended) distribution and the economic activity status distribution collected in the 2011 Census. The mobile sample has also been rim-weighted according to the basic Public Sentiment Index (PSI) figures collected in the landline sample. Herewith the contact information for the latest survey:

[7] These questions only use sub-samples of the tracking surveys concerned, the sample size for each question also varies.
[8] All error figures in the table are calculated at 95% confidence level. “95% confidence level”, meaning that if we were to repeat a certain survey 100 times, using the same questions each time but with different random samples, we would expect 95 times getting a figure within the error margins specified. Media can state “sampling error of ratings not more than +/-2.5 marks at 95% confidence level” when quoting the above figures. Numbers in square brackets { } indicate the rankings.
[9] Such changes have gone beyond the sampling errors at the 95% confidence level, meaning that they are statistically significant prima facie. However, whether numerical differences are statistically significant is not the same as whether they are practically useful or meaningful, and different weighting methods could have been applied in different surveys.
[10] The date of survey for this item was 3-4/12/15 and the overall response rate was 65.2%.
The latest survey conducted in mid-November shows that the 1st to 3rd places regarding people’s satisfaction with disciplinary forces remain to be the Fire Services Department, the Government Flying Service and the Auxiliary Medical Service with satisfaction ratings of 84.1, 79.9 and 79.5 respectively. Next, the 4th to 6th ranks go to the Civil Aid Service, the Customs and Excise Department and the Immigration Department, with satisfaction ratings at 74.3, 74.0 and 73.5 marks respectively. Finally, the 7th to 9th places go to the Independent Commission Against Corruption, the Correctional Services Department and the Hong Kong Police Force. Their satisfaction ratings are 71.9, 68.7 and 66.9 respectively. Besides, people’s latest satisfaction rating toward the PLA Hong Kong Garrison is 64.1 marks.

Survey results show that the satisfaction rate of the Police Force is 59%, dissatisfaction rate 22%, giving a net satisfaction rate of positive 37 percentage points and a mean score of 3.5, meaning between “half-half” and “quite satisfied” in general. Regarding the PLA Hong Kong Garrison, the satisfaction rate is 52%, dissatisfaction rate 8%, giving a net satisfaction of positive 44 percentage points, and a mean score of 3.7, meaning between “half-half” and “quite satisfied” in general.
II. Public Sentiment Index
Background
The Public Sentiment Index (PSI) compiled by POP aims at quantifying Hong Kong people’s sentiments, in order to explain and predict the likelihood of collective behaviour. PSI comprises 2 components: one being Government Appraisal (GA) Score and the other being Society Appraisal (SA) Score. GA refers to people’s appraisal of society’s governance while SA refers to people’s appraisal of the social environment. Both GA and SA scores are compiled from a respective of 4 and 6 opinion survey figures. All PSI, GA and SA scores range between 0 to 200, with 100 meaning normal, the grading reference of the scores are shown below. For methodological detailed please refer to the HKU POP Site at http://hkupop.pori.hk.
POP started to pilot study the “Public Sentiment Index” in year 2010 in collaboration with NowTV. The first survey was conducted in June 2010, followed by a series of monthly tracking surveys in 2011. There were altogether 13 surveys, covered by 11 releases from March 2011 to January 2012. All results have been uploaded to the POP Site.
At the end of June 2012, before the 15th anniversary of the handover of Hong Kong, POP officially released a “PSI analysis” with figures dating back to 1992, spanning over 20 years. Moreover, the frequency of the study was set at twice a month. In October 2012, echoing the start of a new Legislative Council, POP decided to set the cut-off date of all PSI analyses at the Sunday proceeding every 15th and last day of month, whereas the release date was set at the first Thursday following the cut-off date. In July 2017, after the 20th anniversary of the handover, POP further streamlined the release date and mode of PSI analyses to become POP Site release only for the first analysis of each month, and POP Site plus press release for the second analysis of each month. At the same time, the second release was shifted to the first Tuesday of the following month, except under special circumstances.
Cut-off date of the PSI figures released by POP today is November 26, 2017, while that of the next round of release will be December 10, 2017. The tentative release date for the next release will be December 14, 2017 (Thursday).
Latest Figures of PSI
The PSI released by POP today shows that as of November 26, 2017, the latest Public Sentiment Index (PSI) is 122.4, up 13.4 from early November. As for the Government Appraisal (GA) and Society Appraisal (SA), the scores are 118.6 and 114.4, up 9.0 and 15.1 respectively. The chart of PSI, GA and SA are shown below:

Commentary
Note: The following commentary was written by Research Manager of POP, Frank Lee.
Our latest survey shows that the recognition rates of the Fire Services Department, the Police Force, the Independent Commission Against Corruption, the Immigration Department and the Customs and Excise Department are all higher than 95% and those of the Auxiliary Medical Service and the Government Flying Service are higher than 90%, while those of the Civil Aid Service and the Correctional Services Department are higher than 80%. This shows that Hong Kong people are quite familiar with all our disciplinary forces. In terms of relative rankings, the Fire Services Department continues to rank first with a rating of 84.1 marks. The Government Flying Service and the Auxiliary Medical Service rank second and third. The Civil Aid Service, the Customs and Excise Department and the Immigration Department rank fourth to sixth, while the Independent Commission Against Corruption, the Correctional Services Department and the Police Force rank seventh to ninth. Compared with the last survey, the overall rankings of all disciplinary forces have not changed much. In terms of absolute ratings, all nine disciplinary forces get more than 65 marks, seven of which are above 70, which is very good. A point to note is that, the ratings of the Government Flying Service and the Civil Aid Service have reached record high since 2012, while those of the Auxiliary Medical Service and the Independent Commission Against Corruption have reached record high since 2013. The rating of the Police Force is 66.9 marks and continues to be the lowest among the nine disciplinary forces. Its net satisfaction rate is positive 37 percentage points representing a slight increase of 2 percentage points. Meanwhile, the popularity rating of the PLA Hong Kong Garrison stands at 64.1 marks, while its net satisfaction rate stands at positive 44 percentage points, which has significantly increased by 11 percentage points when compared with half a year ago.
As for the Public Sentiment Index (PSI), the latest PSI stands at 122.4, up 13.4 points since mid-November, again reaching a new record high since Carrie Lam took office and back to the level around mid-year 2008. This time both component scores of PSI increase. Specifically, the Government Appraisal (GA) Score that reflects people’s appraisal of society’s governance goes up by 9.0 points to 118.6, and the Society Appraisal (SA) Score that reflects people’s appraisal of the social environment increases by 15.1 points to 114.4. As for the reasons affecting the ups and downs of these figures, we leave it to our readers to form their own judgment using detailed records displayed in our “Opinion Daily”.
